Pressure control mode (PCV)
Pressure control ventilation 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 (Pinsp).
Pressure sensors in the ventilator measure patient airway pressure.
The ventilator automatically adjusts the flow to maintain the set
inspiratory pressure.
PCV mode settings:
• Pinsp
• RR
• I:E
• PEEP
• Pmax
• Rise Rate
