8/1. Connects flowmeter correctly to wall outlet; detects and corrects any leaks
9/2. Adjusts liter flow

Question 4

Volume-Pressure (V-P) Conversion Factors

Answer 4

1. E Cylinder: 622.0 L / 2200 psi = 0.28
2. H Cylinder: 6900.0 L / 2200 psi = 3.14

Question 5

Equation to Determine: How much time there is of O2 in a Cylinder. Using Tank Pressure * V-P Factor / Liter Flow. Example: 2000 psi, E cylinder, 3 L Flow

Answer 5

2000 psi * .28 Factor= 560
560 / 3 L Flow = 186.66
186.66 / 60 min = 3.11
.11 min * 60 sec = 6.6
Answer is 3 hours and 6 minutes

Question 15

Oxygen Analyzer
How to Calibrate

Answer 15

Calibrate Gas to Room Air

Question 16

Oxygen Analyzer
How to Calibrate

Answer 16

Calibrate Gas of Known Oxygen Concentration

Question 17

Oxygen Analyzer
“Rules of Thumb”

Answer 17

1. If patient is set at 50% FiO2 or greater than calibrate to 21% first then 100% second
2. If patient is set at 49.9% FiO2 or lower than calibrate to 100% first then 21% second

• When Calibrating the 100%. Use a 5 L/Flow
  *Once you have calibrated the Oxygen Analyzer you want to ensure your accurate within 2%

Question 18

Room Air Oxygen %
Cylinder Air Oxygen % per Liter for Nasal Canula (NC)

Answer 18

1. Room Air has 21% Oxygen
2. Cylinder Air for 1L has 24% Oxygen For NC
   *For every liter of air in Cylinder the Oxygen % Increases by 4%
3. Cylinder Air for 2L has 28% Oxygen NC
4. Cylinder Air for 3L has 32% Oxygen NC
5. Cylinder Air for 4L has 36% Oxygen NC
