Tidal Volume ExperimentsTidal Volume Experiments
Determine Determine relationship between relationship between chest circumference chest circumference and lung volumeand lung volume
Determine the output Determine the output voltage of the device voltage of the device during a normal and during a normal and a deep breatha deep breath
Measurements used Measurements used to adjust resistor to adjust resistor ratings and gainratings and gain
Expected ResultsExpected Results
Output voltage correlates to lung volumeOutput voltage correlates to lung volume Deep breath threshold will correspond to Deep breath threshold will correspond to
a given output voltagea given output voltage If threshold not reach in a predetermined If threshold not reach in a predetermined
