11 Specifications and theory of operation
Pressure control supplies a constant set pressure during inspiration.
The ventilator calculates the inspiratory time from the frequency and
I:E ratio settings. A high initial flow pressurizes the circuit to the set
inspiratory pressure. The flow then decreases to maintain the set
pressure (Pinspired).
Pressure sensors in the ventilator measure patient airway pressure.
The ventilator automatically adjusts the flow to maintain the set
inspiratory pressure.
