The newest types of mechanical ventilators use which of the following devices to measure airway pressures?
A) Barometers
B) Aneroid manometers
C) Electromechanical transducers
D) Variable orifice pneumotachometers

Question

Quizplus · Accepted Answer

Barometers are used to measure atmospheric (barometric)pressure.Older ventilators incorporated an aneroid manometer into the ventilator circuit.Variable orifice pneumotachometers are used to measure flow.The devices that are used in the current ventilators today are the electromechanical transducers,which include piezoelectric transducers,variable capacitance transducers,and strain gauge transducers.
