Anesthesia Machine Basics Exam with Complete Answers
1. O2 Tank Sizes E and H sizes for oxygen tanks
2. O2 Tank Color Green for both tank and line
3. Full Tank Pressure 2,200 psi; Change at 100-200 psi
4. O2 Tank Pressure Loses about 100 psi/hr
Loss
5. Scavenge Systems Active: vacuum waste gas removal; Passive: gravity waste gas collection
6. Charcoal Canister Removes CO2; Weigh daily, change at 50g gain
7. Flowmeter Reading O2 read in the middle of the floating ball
