Question

Quizplus · Accepted Answer

An "E" cylinder holds about 625 liters of oxygen. For a 1.5-hour transport at 15 L/min, you'll need 1350 liters (1.5 hours x 60 minutes/hour x 15 L/min). Dividing 1350 liters by the 625 liters an "E" cylinder holds gives you 2.16, meaning you'll need three full cylinders to ensure you have enough oxygen for the transport.
