Therapy Modes

The device provides Pressure Control Ventilation (PCV) and Volume
Control Ventilation (VCV) for non-invasive and invasive patients.
Pressure Control ventilation delivers a prescribed pressure to
the patient according to set breath rate and set inspiration time
parameters. This means that each breath is controlled so that a
prescribed amount of pressure is delivered to the patient. The device
oers six dierent Pressure Control modes of operation:
•CPAP – Continuous Positive Airway Pressure
•S – Spontaneous Ventilation
•S/T – Spontaneous/Timed Ventilation
•T – Timed Ventilation
•PC – Pressure Control Ventilation
•PC-SIMV – Pressure Controlled Synchronized Intermittent
Mandatory Ventilation
Volume Control ventilation delivers a prescribed inspired tidal
volume to the patient according to set breath rate and set inspiratory
time parameters. This means that each breath is controlled so that a
prescribed tidal volume is delivered to the patient. The device oers
three dierent Volume Control modes of operation:
•AC – Assist Control Ventilation
•CV – Control Ventilation
•SIMV – Synchronized Intermittent Mandatory Ventilation
