Anaes SAQs · Anaesthetic ventilators
Volume-controlled versus pressure-controlled ventilation
Final SAQ — VCV guarantees the tidal volume with a constant flow and a varying pressure; PCV holds a set pressure with a decelerating flow and a varying tidal volume. PCV suits the stiff lung; VCV guarantees the minute volume.
