Oxygen Tank Duration Calculator

Calculate how long an O2 tank will last based on tank size, PSI, and flow rate.

Tank Size

Current PSI

Flow Rate (L/min)

TIP

Safe transport rule: Always have at least 1.5x the estimated transport time worth of O2. A full E-cylinder at 2 L/min lasts about 280 minutes. Check the gauge before any patient transport.
