Question

ent following a full arrest at 15 liters per minute, you get stuck for Your E tank was full as you left the ER with 2200 psi in it. If ar vou to get out of the elevator, how much oxygen will you have left2 As you are bagging a patient following a full in the elevator. Your E tank was full minutes for you to get out of the elevator R with 2200 psi in it. If it takes 45 You need to take a patient on a 5 hour transport. How many E cylinders will it require if the patient is on 5 Ipm nasal cannula? A patient on home oxygen is taking a trip to the doctor. She has only D cylinders available. She is currently on 2 Ipm of oxygen continuously. How long will the D cylinder last?

Answer 1

$Duration of Flow = Oxygen Tank Conversion Factor *Remaining Tank Pressure (psi)/Continuous Flow Rate (L/min)$1) Oxygen tank(E tank)pressure =2200 psi

Oxygen tank conversion factor(E TANk) =0.28

Continous flow rate =15 l/min

Duration of flow =0.28 x 2200 /15 = 41.066 =41.07 min

Oxygen balance after 45 min = 45 - 41.07 = 3.93 min left

2) as per the calculations

0.28 x 1900 /5 = 106.4 min = 1 hrs 8 min

for 5 hours journey =106.4 x5 =188.7 around 10 E cylinders need for 5 hour transporations

3) D cylinder PSI = 1900 psi

as per formula = 0.16 x 1900 / 2 = 152 min = 2 hrs 53 min
