3.1 definitions
e following terms appear throughout this manual:
Apnea A condition marked by the cessation of spontaneous breathing.
BPM Breaths Per Minute
CPAP Continuous Positive Airway Pressure
EPAP Expiratory Positive Airway Pressure
Exhaled Tidal Volume (V
TE
) e exhaled volume of each breath
High Priority Alarm An alarm signal indicating a condition that requires immediate attention.
IPAP Inspiratory Positive Airway Pressure
LED Light Emitting Diode
LEAK e amount of airflow leak detected by the device.
Low Minute Ventilation A condition in which you are not receiving a specified volume of air on
a per minute basis.
Low Priority Alarm An alarm signal indicating an informational message.
Medium Priority Alarm An alarm signal indicating a condition that requires operator
awareness.
Minute Ventilation (MinVent) e volume of air received by the patient on a per minute basis.
Operate State e state of the device when the device and the airflow are both on.
OSA Obstructive Sleep Apnea
Ramp A feature that may increase patient comfort when therapy is started. e
ramp feature reduces the pressure and then gradually increases (ramps) the
pressure to the prescription setting, so you can fall asleep more comfortably.
Respiratory Rate (RR) e patient’s rate of respiration.
Rise Time e time it takes for the device to change from EPAP to IPAP. You can
adjust this time for your comfort.
Standby State e state of the device when the device is on, but the airflow is off.
3.2 What is Bi-level ventilation?
Bi-level ventilation with the BiPAP autoSV device helps you to breathe by supplying two levels of air
pressure. e device provides a higher pressure—known as IPAP (Inspiratory Positive Airway Pressure)—
when you inhale, and a lower pressure—known as EPAP (Expiratory Positive Airway Pressure)—when you
exhale. e higher pressure makes it easier for you to inhale, and the lower pressure makes it easier for you
to exhale.
