PreventiveMaintenance: maintenance performed at regular intervals
Within the text of this manual, controls, alarms, buttons, etc. aredesignated by the labeling name as they appear on the ventilator, e.g.:Plimit (pressure limit), Ptrig (pressure trigger), SPONT (spontaneousmode).
Please review all warnings and cautions outlined in this manualbefore operating the ventilator.
WARNINGS AND CAUTIONS
Strictly follow this Manual. Any use of the product requires fullunderstanding and strict observation of all sections of these instructions.The equipment is only to be used for the purpose specified underIntended Use (See Section 2) and in conjunction with appropriateairway monitoring. Observe all WARNINGS and Cautions as renderedthroughout this manual and on labels on the equipment.
To maintain grounding integrity, connect only to a hospital gradereceptacle. Always disconnect power supply before servicing.
DANGER, there is a risk of explosion if used in the presence offlammable anesthetics.
All settings and adjustments in the different modes of ventilation have tobe made according to the therapy prescribed by a physician.
Newport Medical Instruments, Inc. cannot warrant or endorse the safeperformance of third party humidifiers for use with the E100M Ventilator.
We recommend contacting the manufacturers/distributors of third partyhumidifiers about compliance of their products with the requestedperformance characteristics.
General Warnings
Typing Conventions
DEFINITIONS
OPERATORS RESPONSIBILITY
1-4 SER1500 D0105
Do not use antistatic or electrically conductive patient circuits. Alwaysuse a clean, sterile breathing circuit.
The ventilator is ready for operation only when:a) it is completely assembled andb) a Quick Check procedure has been performed successfully.
Whenever a patient is connected to the ventilator, constant attention byqualified medical staff is recommended.
If a fault is detected in the ventilator and its life support functions are indoubt, discontinue use and use an alternative method of ventilation.
If the built-in monitoring malfunctions, provide a substitute in order tomaintain an adequate level of monitoring.
Failure to identify and correct alarm situations may result in patientinjury.
Use an external monitor to verify the accuracy of the oxygenconcentration delivered to the patient at all times.
When the Low Battery ( Battery ) audible alarm soundscontinuously, only 10% of the internal battery charge remains and analternate power source should be found immediately. Charge the batteryfor a minimum of 5 hours before again powering the ventilator from theinternal battery. This will provide approximately 80% of the batterycharge. If the battery is completely depleted, it will take approximately14 to 16 hours to fully recharge.
The internal battery should be fully charged at least once every 6months to ensure that it remains functional.
Water traps should be used in appropriate locations of the breathingcircuit in order to prevent water that has accumulated in the circuit frombeing drained towards the patients airway.
Newport Medical Instruments, Inc. cannot endorse or warrant the safeperformance of nebulizers currently available when used with the E100MVentilator. Specifically, some disposable nebulizer assemblies operatewith flow rates different from the 10 L/min delivered by the ventilator at28 psig. We recommend contacting the manufacturers/distributorsselling nebulizing devices about compatibility of their products with therequested performance characteristics.
The flow resistance of filters is liable to increase through use, due toboth aerosol usage and humidification level. Make certain that filters arechanged regularly (especially those in the expiratory limb of thebreathing circuit).
The Plimit control should be set 4 to10 cmH2O/mbar above the _
Pawalarm limit as a safety pop-off when volume ventilating. In volumecontrol ventilation, an incorrect setting of the Plimit control could causesome volume to be vented. When pressure ventilating, the Plimitcontrol should be set to the plateau pressure level that is desired.
SECTION 1
SER1500 D0105 1-5
The E100M Ventilator is guaranteed to perform within specification whenthe Newport Medical permanent breathing circuit and the permanentexhalation valve are utilized. The Newport Medical permanent breathingcircuit with proximal sensing line is available in infant or adult sizes. If analternate circuit is used, the proximal pressure line must be a 1/8 in (3.2mm) I.D. for proper ventilator performance.
Only a Newport Medical permanent exhalation valve should be usedwith the E100M Ventilator.
Use only dry, clean, compressed air and medical grade oxygen. Water inthe air or oxygen supply can cause equipment malfunction and damage.
Mains voltage must correspond to the voltage range selected on thepower module of the ventilator. Always replace a blown fuse with one ofproper rating for corresponding voltage range.
Do not place containers of liquids in the immediate vicinity or on top ofthe E100M Ventilator. Liquids that get into the ventilator can causeequipment malfunction and damage.
Periodically inspect the Air Inlet Water Trap. Drain water from the bowlwhen necessary by depressing the pin at the bottom of the bowl.

FRONT PANEL CONTROLS
Front panel controls that have corresponding indicators (i.e. Paw Alarmcontrol with Paw/Paw indicators) are included with the description ofthe control. The E100M front panel is shown in Figure 1.
MODE Control
A/CMV(Assist/Control Mandatory Ventilation)
The minimum number of time triggered mandatory breaths is determinedby the control. The total number of mandatory breaths is a result ofthe setting and patient triggers. Set the Ptrig as close to baselinepressure as possible so that all patient efforts are recognized as patienttriggers. The indicator for A/CMV is lit green while operating in thismode.
NOTE: If the Ptrig setting is not adjusted to a level that allows thepatients inspiratory effort to be detected, the A/CMV mode resemblesControl mode.
SIMV(Synchronized Intermittent Mandatory Ventilation)
The number of time triggered mandatory breaths is determined by the control. The patient can take spontaneous breaths between the deliveryof the mandatory breaths. Set the Ptrig as close to baseline as possibleso that all patient efforts are recognized as patient triggers. This allowsthe E100M to synchronize the mandatory breaths and spontaneousTime-Limited Demand Flow breaths with patient effort. Time-LimitedDemand Flow may be used to support spontaneous efforts with a higherinitial flow which then drops to the lower Spont Flow. The indicator forSIMV is lit green while operating in this mode.
SPONT + APNEA A/CMV(Spontaneous Ventilation + Apnea A/CMV)
All breaths are spontaneous. Set the Ptrig as close to baseline aspossible so that all patient efforts are recognized as patient triggers.Time-Limited Demand Flow may be used to support spontaneous effortswith a higher initial flow which then drops to the lower Spont Flow. If thepatient stops breathing and it results in an Apnea alarm violation, A/CMVbreaths are delivered at the face panel control settings until the patienteffort results in four consecutive patient triggered breaths. The indicatorfor SPONT + APNEA A/CMV is lit green while operating in this mode.

P trig Control and SPONT Indicator (sensitivity)
The Ptrig control knob adjusts the patient trigger sensitivity setting onthe E100M. The trigger sensitivity setting determines the amount ofnegative pressure (inspiratory effort) the patient must generate in thebreathing circuit in order for the E100M to detect the effort (trigger). On"power up" of the ventilator, the trigger is set at 5 cmH2O/mbar.
When you rotate the knob, you will feel it click slightly. Each clickrepresents a trigger sensitivity level change of ~0.14 cmH2O/mbar.Rotating it through seven clicks changes the trigger sensitivity by onecmH2O/mbar, i.e., one pressure gauge segment. (The selected segmentblinks on the electronic pressure gauge.) Rotate the Ptrig controlcounter-clockwise to increase the patient effort required to trigger andclockwise to decrease the effort required.
The Spont indicator blinks when the E100M detects a trigger. TheApnea alarm time delay interval (Apnea ) is reset at the same time.
See Theory of Operation, Section 4, for more details on adjusting Ptrig.
Spont indicator blinks yellow: Indicates a spontaneous effort is detectedby the Ptrig.
Spont indicator doesnt blink: Indicates no spontaneous effort is detectedby the Ptrig.
NOTE: Each time the Spont indicator blinks or a mandatory breath isdelivered, the Apnea alarm delay is reset.
Range: 10 to +25 cmH2O/mbar

Reservoir Bag Connection
The two liter Reservoir Bag provides a reservoir of gas which is availableto meet the peak flow needs of a spontaneously breathing patient.Mixed gas from the SPONT V1 switch and/or SPONT V2 flowmeterenters the Reservoir Bag prior to entering the patient circuit. The patientcan draw gas from the Reservoir Bag during peak need. Adjust thespontaneous flow (SPONT V1 and SPONT V2) to meet averagespontaneous flow needs of the patient rather than peak spontaneousflow needs. This helps to conserve gas supplies.
Caution If the patients effort empties the Reservoir Bag, it is possiblefor the patient to pull ambient gas in through the Emergency IntakeValve. Make sure that SPONT V1 and SPONT V2 are adjusted so thatthe patient does not empty the Reservoir Bag during spontaneousbreathing.
NOTE: Time-Limited Demand Flow may be set to meet the patientspeak flow needs. In this case the patient breathes from SPONT V1 andSPONT V2 and the reservoir bag at end exhalation only.

GENERAL SYSTEMS OVERVIEW
The Newport Ventilator Model E100M is a pneumatically powered,microprocessor controlled, pressure, time or manually triggered, timecycled, flow or pressure limited ventilator, with Time-Limited DemandFlow and continuous flow for spontaneous breathing. It is capable ofventilating neonate through adult patients. An internal lead acid batterypowers the ventilator for approximately 6 to 8 hours when fully charged.
The electronic control system incorporates two microprocessors on themain board. The control microprocessor is responsible for all electricallyactivated mechanical components. The monitor processor is responsiblefor the electronic pressure gauge and all displays. The main componentof the pneumatic system is a pneumatic interface valve activated by anelectrically controlled pilot valve. These two valves are responsible forinitiating gas delivery during mandatory breath and Time-LimitedDemand Flow inspiration. A separate valve controls gas delivery the restof the time.
An emergency intake valve allows the patient to pull ambient air into thebreathing circuit in the event of a complete loss of supply gas pressure.Opening pressure is approximately 2 cmH2O/mbar in this condition.
A/CMV(Assist/Control Mandatory Ventilation)
In A/CMV, mandatory breaths are time triggered at the setting. Apatient can trigger mandatory breaths in addition to, or in place of, thetime triggered breaths if the effort they generate causes airway pressureto meet the Ptrig setting. Every patient effort that causes airwaypressure to meet the Ptrig setting results in a mandatory breath. Tidalvolume is determined by the V and tI settings in volume control, anddetermined by V, tI and Plimit settings in pressure limited ventilation.
WARNING A leak in the breathing circuit can cause the ventilator toauto-trigger. Monitoring, including high and low minute volumealarms, should be used to detect this condition, and the clinicianshould frequently check the ventilator to verify baseline stability.
SIMV(Synchronized Intermittent Mandatory Ventilation)
In SIMV, the patient receives a fixed number of time/patient triggeredmandatory breaths and may breathe spontaneously from the ventilatorsTime-Limited Demand Flow and/or spontaneous flow. See Figure 4-1.
THEORY OF OPERATION
4-2 SER1500 D0105
The first breath the patient triggers in any mandatory breath interval isthe patient triggered mandatory breath. The patient has the rest of theinterval to breathe spontaneously. If the patient stops triggering breathsand one complete mandatory breath interval has elapsed without atrigger, a time triggered mandatory breath is delivered.
A mandatory breath lockout interval is activated whenever the patienttriggers a mandaory breath. This limits the number of mandatory breathsthe patient receives in 60 seconds to the (b/min) setting.
WARNING The SPONT V1 switch and/or SPONT V2 flowmetermust be turned on in SIMV and SPONT modes to provide gas forpatient spontaneous breathing even if Time-Limited Demand Flow isenabled.
SPONT + APNEA A/CMV(SPONTANEOUS + APNEA A/CMV VENTILATION)
If the Apnea alarm is not violated in SPONT + APNEA A/CMV, this modeperforms the same as SPONT mode. Please review SPONT in thissection.
If no patient triggers occur during the apnea alarm delay intervalselected, back-up breaths are delivered according to the A/CMVsettings (V, , tI, Plimit). The Apnea alarm indicator blinks and the audiblealarm activates. If four consecutive patient triggered breaths aredetected, the Apnea alarm indicator latches, the audible alarm issilenced, and back-up breaths cease. Press Reset to cancel thelatched indicator.

WARNING Before switching to the SPONT + APNEA A/CMV mode,always make sure the Plimit, , tI, and Vcontrols are setappropriately for the patient.
WARNING The SPONT V1 switch and/or SPONT V2 flowmeter mustbe turned on in SIMV and SPONT modes to provide gas for patientspontaneous breathing even if Time-Limited Demand Flow isenabled.
SPONT (SPONTANEOUS VENTILATION)
In SPONT, the patient may trigger Time-Limited Demand Flow and/ormay breathe exclusively from the spontaneous flow through thebreathing circuit and reservoir bag at the selected FIO2. The patient hascontrol over each breath. CPAP may be added using the PEEP/CPAPcontrol. Adjust the Ptrig control or enable ATC so that the E100M candetect the patients spontaneous efforts. If detected, the Spont indicatorblinks yellow, and the apnea alarm delay interval is reset.
WARNING The SPONT V1 switch and/or SPONT V2 flowmetermust be turned on in SIMV and SPONT modes to provide gas forpatient spontaneous breathing even if Time-Limited Demand Flowis enabled.
DuoFlow
The DuoFlow system allows the user to control mandatory andspontaneous flow separately. The V control determines the flow formandatory breaths, manual inflations, and Time-Limited Demand Flow.The SPONT V1 (toggle switch) and V2 (flowmeter) determine the flowavailable for spontaneous breathing either exclusively or after the Time-Limited Demand Flow duration elapses. The reservoir bag providesadditional gas in the event that patient spontaneous flow exceeds theSPONT V1 and V2 setting.
The patient breathes from mandatory flow during mandatory and Time-Limited Demand Flow breaths, and from SPONT V1 and V2 flow duringspontaneous breathing. When mandatory flow is delivered to the patient,SPONT V1 and V2 are switched off (electronically), and vice-versa. SeeFigure 4-2.
THEORY OF OPERATION
4-4 SER1500 D0105
Figure 4-2DuoFlow SYSTEM
Time-Limited Demand Flow provides flow support for a patient's peakspontaneous breathing flow needs. The Time-Limited Demand Flowcontrol determines the duration of time that the mandatory flow rate willbe delivered at the onset of a patient triggered spontaneous breath.When the Time-Limited Demand Flow time elapses, the spontaneousflow (determined by the SPONT V1 and V2 settings) is delivered for theremainder of the exhalation period.
Time-Limited Demand Flow can provide a higher level (V setting) of flowto the patient at the onset of a patient triggered spontaneous breath,after which the patient completes inspiration from the SPONT V1 and V2flow. Providing the patient with a higher level of flow during the time theyhave the highest demand can decrease imposed work of breathing.
Use of Time-Limited Demand Flow can allow the caregiver to set a lowerlevel of SPONT V1 and V2 since the spontaneous flow no longer needsto meet the patients spontaneous peak flow needs. Setting a lower levelof SPONT V1 and V2 helps to decrease expiratory resistance for patientexhalation and decrease gas consumption. The V, Time-LimitedDemand Flow, and SPONT V1 and V2 controls should be adjusted tomaximize the patient's comfort during spontaneous breathing.
The Time-Limited Demand Flow control is adjustable from -1.0 secondand functions in SIMV, SPONT + APNEA A/CMV, and SPONT modes. TheTime-Limited Demand Flow indicator lights any time the Time-LimitedDemand Flow control is set above , except when the mode is set toA/CMV. The exhalation valve remains at the PEEP/CPAP setting levelduring the Time-Limited Demand Flow portion of a spontaneous breath.

Figure 4-3 provides an example of what occurs in SIMV when Time-Limited Demand Flow is activated. The V control determines the flowdelivered during mandatory breaths and Time-Limited Demand Flowportion of spontaneous breaths.
The tI control determines the inspiratory time that mandatory flow isdelivered for mandatory breaths. Time-Limited Demand Flow controldetermines the time that mandatory flow will be delivered prior toswitching back to the spont flow at the onset of each spontaneousbreath. In between the mandatory breaths and Time-Limited DemandFlow, spontaneous flow is delivered according to the SPONT V1 and V2setting.

SIMV with Time-Limited Demand Flow
At the onset of each spontaneous breath, flow enters the patientbreathing circuit at the mandatory flow setting. When the Time-LimitedDemand Flow setting time elapses, the flow entering the circuit switchesto the SPONT V1 and V2 level.
P limit(Pressure Limited Ventilation)
Range: 0 to 120 cmH2O / 0 to 118 mbar
Pressure Limited Ventilation has been used for neonatal / pediatricventilation for many years. In recent years it has gained popularity foradult patients. The proposed benefit of Pressure Limited Ventilation inadults with obstructive disease is that gas distribution may be enhancedwhile ventilating at lower airway pressures.
The Plimit control determines the maximum pressure in the patientcircuit during a spontaneous, mandatory, or manual breath. Clockwiserotation of the knob increases the maximum pressure (pop-off) setting,and counter-clockwise rotation decreases the maximum pressure. ThePlimit control works in all modes and can be adjusted from 0 to 120cmH2O / 0 to118 mbar.

Pressure Limited Ventilation differs from Volume Control Ventilation inthat each breath is pressure limited, and volume variable. A mandatorybreath becomes pressure limited when airway pressure is equal to thePlimit control setting. When this occurs, the Plimit control vents flow asneeded to prevent pressure from rising above the pressure limit selectedby the caregiver. With adequate flow, airway pressure rises to the Plimitthen flattens or plateaus for the remainder of the set inspiratory time (tI).
The volume delivered during a pressure limited breath varies, dependingon the V setting, the duration of the inspiratory time and the patientstime constant. As demonstrated in Figure 4-4, physiologic changes suchas a change in the patient's resistance or compliance, or changes withinthe gas delivery system such as leaks or obstructed filters, can all affectthe duration of the pressure plateau and consequently the tidal volumedelivered to the patient.
NOTE: Exhaled volume monitoring can be very useful and isrecommended when using pressure limited ventilation.
Figure 4-4Pressure Limited Ventilation Open Circuit
Changing the V (mandatory flow) or tI (inspiratory time) setting affectsthe duration of the airway opening pressure plateau for mandatorybreaths. The V determines the inspiratory pressure slope/rise formandatory breaths.
Flow resistance and compliance affecthow fast airway pressure rises.
Flow delivered from the ventilator does not necessarily enterthe patient airway. This Flow escapes from the P limit valve after the P limit level is achieved at the airway. VENTED FLOW DOES NOT contribute to the delivered tidal volume.
Delivered volume will vary as patient effort, compliance and resistance varies.

Figure 4-5 shows an example of how the V setting affects the inspiratorypressure slope/rise and pressure plateau. The V setting for breath #1 is45 L/min and for breath #2 is 30 L/min. The tI and Plimit settings are thesame for both breaths.
Breath #1 has a much faster pressure rise due to the higher flow (50L/min). As a result, the pressure plateau level (Plimit setting) for breath#1 is reached rapidly, causing flow entering the airway to begin todecrease quickly. With breath #2, flow entering the airway does notbegin to decrease until approximately 75% of the elapsed inspiratorytime.

NOTE: Always verify the Plimit setting after a change is made to the V ortI controls.
NOTE: The Plimit control is factory preset at its minimum setting (fullycounter-clockwise).
NOTE: The purpose of setting the _
Paw alarm when pressureventilating a patient is to have a secondary safety back-up in the eventof a Plimit valve failure.
WARNING When volume ventilating a patient, make certain thePlimit control is set higher than the pressure required to deliver theset VT, since volume will be vented to the atmosphere when thePlimit is reached.
WARNING Make certain that appropriate monitoring is in placewhen ventilating a patient with pressure targeted ventilation. Anocclusion of the patient circuit or ET tube may not result in a Paw(high pressure) alarm violation.

Ptrig CONTROLRange: 10 to 25 cmH20
The Ptrig control knob adjusts the patient trigger sensitivity setting onthe E100M. The trigger sensitivity setting determines the amount ofnegative pressure (inspiratory effort) the patient must generate in thebreathing circuit in order for the E100M to detect the effort (trigger). Onpower up of the ventilator, the trigger is set at 5 cmH2O/mbar.
When you rotate the knob, you will feel it click slightly. Each clickrepresents a trigger sensitivity level change of ~0.14 cmH2O/mbar.Rotating it through seven clicks changes the trigger sensitivity by onecmH2O/mbar, i.e., one pressure gauge segment. (The selected segmentblinks on the electronic pressure gauge.) Rotate the Ptrig controlcounter-clockwise to increase the patient effort required to trigger andclockwise to decrease the effort required.
The Spont indicator blinks when the E100M detects a trigger. The Apneatime delay interval is reset at the same time.
Adjusting the Ptrig control: Adjust the Ptrig control until you reach asetting at which it is easy for the patient to trigger the ventilator but notlikely that the ventilator will trigger from non-patient generated circuitpressure fluctuations. From this point, non-patient generated triggerswill be refered to as "artifact triggers".
When you adjust the PEEP/CPAP control the trigger level automaticallymoves in conjunction with the change in baseline pressure. If baselinepressure changes as a result of adjusting you need to re-adjust thetrigger sensitivity manually.
If Time-Limited Demand Flow is enabled for spontaneous breathing, aspontaneous breath trigger is followed by a trigger lock-out period untilbaseline pressure stabilizes or until 1.5 seconds elapse, whichever isshorter. This lock-out helps to prevent multiple augmented flowtriggering during a single spontaneous patient effort.
If it appears that the E100M is not detecting patient efforts (Spontindicator not "blinking") with the trigger level set to within one or twocmH2O/mbar of baseline, you may want to reassess the SPONT V1 andV2 settings.
SECTION 4
SER1500 D0105 4-9
ADVANCED TRIGGER CONTROL (ATC )The Advanced Trigger Control (ATC ) button activates a function thatautomatically manages the Ptrig setting in any mode. The ATC functionmanages the trigger sensitivity setting within an allowable range (betweenthe target trigger as defined in the ATC Target Trigger Look Up Table and2 cmH2O/mbar below baseline pressure) with the goal of making it easyfor the patient to trigger the ventilator while keeping the ventilator fromartifact triggering. (See description of artifact triggering in the Ptrig Controlsection and definitions/conditions in the table on Page 4-13.)
There are two fundamental aspects of automatic trigger management,(1) optimization, which includes baseline assessment and attempting toset trigger at an optimized value, and (2) basic trigger adjustment up ordown.
(1) Optimization of the trigger level and reassessment of baselinepressure occurs:
when the ATC function is activated by pushing the button;
when 30 minutes of operation has elapsed since the last assessment;
each time the PEEP/CPAP control is adjusted.
How the ATC trigger setting is determined during assessment andoptimization:
The microprocessor assesses baseline pressure and then selects atarget setting for the trigger level according to the ATC Target TriggerLook Up Table.
If the E100M does not artifact trigger at the target trigger setting, asdetermined by the definitions listed in the Artifact Trigger Conditions onpage 4-13, the trigger setting remains at the target value.
If an artifact trigger condition is identified, ATC backs off on the triggersetting (becomes less sensitive) by 0.14 cmH2O/mbar until the artifacttrigger condition is eliminated or until the trigger is 2 cmH2O/mbarbelow the assessed baseline.
(2) In between optimization events, ATC provides basic adjustmentof the trigger setting, either up or down.
Trigger is never adjusted closer to baseline than the target trigger leveldefined in the ATC Target Trigger Look Up Table and it is never adjustedto a position further than 2 cmH2O/mbar below the most recentlyassessed baseline.
THEORY OF OPERATION
4-10 SER1500 D0105
If no patient efforts have been detected in the last 15 seconds in A/CMVor SIMV mode (SPONT indicator not blinking), the trigger level willmove 0.28 cmH2O/mbar closer to the baseline. If the patient effort stillgoes undetected for another 15 seconds, the trigger will again move0.28 cmH2O/mbar closer to the baseline. This will continue until apatient breath is detected or until the trigger reaches the target triggerdefined in the ATC look-up table. For both SPONT modes, the timecriteria is 32 seconds rather than 15 seconds.
Each time an artifact trigger condition is identified in any mode, ATC willmove the trigger level down (more negative) by 0.14 cmH2O/mbar but itwill never move the trigger more than 2 cmH2O/mbar below baseline.
NOTE: For information on manually adjusting the trigger level, seeprevious section, Ptrig Control.
NOTE: When ATC is first activated, self-triggering of the ventilator mayoccur until the ideal trigger setting is determined.
NOTE: When SPONT V1 or V2 is changed, a shift of the Pbase mayoccur. Press the ATC button to deactivate and press it again toreactivate the ATC function so that trigger is immediately adjusted to thenew Pbase.
AUTO-SET ALARM (AS )
Range: _
Paw Alarm 15 to 120 cmH2O /15 to 118 mbarPaw Alarm 5 to 115 cmH2O / 5 to 113 mbar
The Auto-Set (AS ) alarm button activates a function that automaticallyselects
_Paw (high pressure) and Paw (low pressure) alarm settings.
The settings are selected according to the current peak airway pressurefor mandatory breaths at the time the button is pressed. The ASbutton must be pressed again in order to select new
_Paw and Paw
alarm settings after any change is made to a primary ventilator control.Primary controls include Mode, Inspiratory Time (tI), Flow (V
), Frequency() and PEEP/CPAP.
The _
Paw alarm setting will increase a maximum of 10 cmH2O from itsprior setting with each activation of the AS button. With the exceptionof an increase to the
_Paw alarm setting, the AS function can move the
Paw and _
Paw alarm settings anywhere within their specified ranges.If the Paw alarm continues to be violated after the 10 cmH2O increase,the AS function turns off. This helps alert the user to the fact that thechanges made to the ventilator or changes in the patient condition haveresulted in a significant increase in peak pressure. Press the AS buttonagain to reactivate the AS function after verifying that all primarycontrols are set at a safe level. Primary controls include Mode,Inspiratory Time (tI), Flow (V
), Frequency () and PEEP/CPAP.
SECTION 4
SER1500 D0105 4-11
NOTE: The peak airway pressure for the AS function is determined byaveraging the peak pressure for two consecutive mandatory breathswithout a Paw alarm violation.
NOTE: The minimum alarm setting for Paw is 5 cmH2O abovebaseline. Paw must be 2 cmH2O above Paw. If the minimum criteriais not met, the alarm bars remain at the current settings and the ASfunction and indicator turns off.
AS alarm indicator lit green: _

Press the AS button once to cause the high and low pressure alarmsettings to be evaluated and adjusted for the current peak airwaypressure.
Activating the AS alarm function after power up:
After the MODE, , V, tI, PEEP/CPAP and Plimit controls are adjusted tothe appropriate settings and the patient is connected to the ventilator,press theAS alarm button to set the alarms. The indicator on the ASbutton will light indicating AS is on, and the Paw and Paw alarmbars on the pressure gauge will blink until the selection of
_Paw and
Paw settings are establised.
WARNING Make certain the patient is being ventilated at anappropriate peak airway pressure before pressing the AS alarmbutton.
If a Paw violation occurs during the AS alarm selection process:
After the AS function is selected, the _
Paw alarm setting can increaseup to 10 cmH2O above the existing setting. If peak pressure reaches 10cmH2O above the alarm's previous setting (i.e. 40 cmH2O/mbar), thebreath is pressure cycled to exhalation, the Paw alarm indicator blinks,the audible alarm activates, and the AS indicator turns off.
Each time the AS button is pressed (re-activating the AS function), the_
Paw alarm bar can increase an additional 10 cmH2O/mbar. If a Pawalarm violation occurs during the AS alarm setting, the AS indicatorturns off. You may continue this sequence until the breaths are no longerpressure cycling (max. 120 cmH2O/mbar).
