Calculating Cylinder Use

Question 1

Find Remaining Volume

Answer 1

V1/P1= V2/P2
V2 = (P2/P1) x V1
Example:
(750 psi/2200 psi) x 660 L = 225 L

Question 2

Find Current Use

Answer 2

Total O2 Consumption=FGF+Minute Ventilation
FGF = 2 L/min
VE = VT x RR = 0.7 L x 10 bpm = 7 L/min
Total O2 Consumption = 2 L/min + 7 L/min
