FDA-Cleared, Hypertension Treatment Device
Clinically proven therapeutic breathing device Sustained blood pressure reductions within 8 weeks No side effects, no drug interactions Seven clinical trials published in peer-reviewed journals Relaxing, pleasant and easy to use
“We found that RESPeRATE was very helpful to many of our patients who experience shallow breathing. And patients, some of whom don’t have high blood pressure, say it simply helps them relax. We use it for patients to take home as a means of reinforcing our biofeedback work with them.”
Leonard Schwartzburd, PhD Clinical Psychologist & Director of the Clinical Institute of
Behavioral Medicine Berkeley, California

RESPeRATE: FDA Indication for Use
Specifically indicated for adjunctive treatment of hypertension & reduction of stress
Can be safely used with pharmacological and/or non-pharmacological interventions
Does not require a prescription Any changes in medication should be discussed with the doctor who
prescribed them
RESPeRATE Indications for use (FDA k# 020399 OTC)The RESPeRATE is intended for use as a relaxation treatment for the reduction of stress by leading the user through interactively guided and monitored breathing exercises. The device is indicated for use only as
an adjunctive treatment for high blood pressure, together with other pharmacological and/or non-pharmacological interventions.

Therapeutic Breathing Pattern Beneficial for Hypertension
Slow & deep breathing (<10 breaths/min)
Long exhalation
Without effort
• Sympathetic Outflow • Vagal Outflow • Baroreflex sensitivity • Chemoreflex sensitivity

Computerized unit – detects inspiration & expiration times and generates guiding tones with slightly longer duration
Headphones – hear tones with which user SYNCHRONIZES breathing

Clinical Trials Highlights
7 separate published clinical trials1-6 (over 280 patients), of which 4 were randomized, controlled 1,2,5
Significant & sustained 14/8 mmHg average reduction for high blood pressure, independent of both gender and medication status
Greater reductions for older patients (18/8 mmHg for age>65)
Found effective for Refractory Hypertension6 and Isolated Systolic Hypertension5
Significant and consistent results measured at the clinic1-6, at home2-6 and with a 24-hour ambulatory blood pressure monitor3
No observed side effects

What RR Can Tell About Its Use?
To user
Displays compliance upon
turning ON
Displays compliance & performance -Press STAT
Goal: at least 45 min.
Feedback on breathing rate and compliance
# slow breathing minutes done in
last 7 days

Client’s Role in “Treatment with RESPeRATE”?
15-min daily session
Quiet room, no other activities
Record displayed “compliance” in a diary * (optional)
Monitor morning BP and record in a diary (optional)
Follow-up visits with healthcare professional as requested
* The displayed compliance is very important for motivatingthe patient and to give a feeling of control/ self-empowerment.
31
RESPeRATE User Survey (2006)Performed in partnership with Ipsos- Vantis
Good compliance: 90% use on regular basis, 73% >2x/week
(8-12 weeks from purchase)
Improved BP: 85% reported RESPeRATE improved their BP
Improved Sense of Well-being: 85% reported RESPeRATE
had a positive impact on their general well being
Easy to Use: 95% reported RESPeRATE was easy to use or
took just a few sessions to learn
