Answer to Question 1

ANS: A
The Bird Mark series ventilators use magnetism versus gas pressure as their basic principle of op-eration.

Answer to Question 2

ANS: A
When set on air-mix, a Bird Mark 7 or 8 will direct the incoming source gas to the jet of the air-mix Venturi. The gas going to the patient is from the Venturi jet, the air entrained by the Venturi system, and the nebulizer jet.
