Answer to Question 1

ANS: C
In a spring-loaded bellows model, an adjustable spring atop a bellows applies a force per unit ar-ea, or pressure (P = Force/area). Tightening of the spring creates greater force and therefore greater pressure. The bellows contains pre-blended gas (air and oxygen), which is administered to the patient.

Answer to Question 2

ANS: A
The rotary drive piston creates a flow pattern that is slow at the beginning of inspiration, achieves highest speed at mid-inspiration, and tapers off at end-inspiration, creating a sinusoidal wave-form (sine waveform).
