- Take the patient off and bag ventilate
How many more times greater is misuse of the anesthesia gas delivery
equipment than equipment failure - ✔✔ANS✔✔3x, lack of

volume
How is O2 manufactured by -✔✔ANS✔✔Fractional distillation
of liquified air. This is the most common method
How are O2 and N20 stored -✔✔ANS✔✔O2 is stored as a gas
and N2O is stored as a liquid
