Calculation

Question 1

Tank Calculation

Answer 1

Duration of Flow =

Oxygen Tank Conversion Factor * Remaining Tank Pressure (psi) / Continuous Flow Rate (L/min)

Question 2

Oxygen Cylinder Conversion Factors

M Tank

Answer 2

M tank = 1.56

Question 3

Oxygen Cylinder Conversion Factors

H/K Tank

Answer 3

H/K Tank = 3.14

Question 4

Oxygen Cylinder Conversion Factors

G Tank

Answer 4

G Tank = 2.41

Question 5

Oxygen Cylinder Conversion Factors

E Tank

Answer 5

E Tank = 0.28

Question 6

Oxygen Cylinder Conversion Factors

D Tank

Answer 6

D Tank = 0.16

Question 7

Total Arterial O2 Content

Answer 7

CaO2= (1.34 x Hb x SpO2) + (PaO2 x 0.003)

Question 8

How to Determine Pt Inspiratory Flow

Answer 8

Flow= Volume (L)/time (min)

Question 9

Determining the total flow in a high flow delivery device

Answer 9

If air/O2 is for example 30 then it is 8:1 so for every 1 litre of oxygen 8 L is being entrained into the device

for total flow add the two toegther (=9) and then multiple by the set flow

Question 10

Calculating Flow in Liquid Oxygen System

Answer 10

Gas Remaining= (Liquid Weight [lb]) x 860/ 2.5 L/Ib

Duration of Contents (min)= Gas Remaining (L)/ Flow (L/min)

Remeber 1 L of Liquid O2 = 2.5 lb
