– The InfantStar interrupts the inspiratory gas flow with a valve bank.
Some authors regard this device as a jet ventilator because of its
principle of operation [83, 41].
– The Babylog 8000 delivers a high inspiratory continuous flow (max
30 l/min) and generates oscillations by rapidly switching the expira -
tory valve. Active expiration is provided with a jet Venturi system.
