Research Facts
This is a pressure cycle respirator which depended on the compliance and resistance of the patient's lungs to determine the volume of gas; the disadvantage of this respirator is that it had limited applications; since it was pressure-dependent, the operator was never sure of volumes; this respirator could not be used on neurological patients who did not breathe normally
