O2 Duration

O2 Duration is an oxygen consumption calculator for various oxygen cylinder sizes. This is the easiest way to quickly determine the approximate number of minutes until an oxygen tank will be depleted of oxygen. This tool is a must have for Nurse's and EMT’s who work with portable oxygen cylinders.

The application allows you to select cylinder tank sizes A, B, D E, G, H, K and M. With the current tank pressure and desired flow rate, the app will display the oxygen duration in minutes. Additionally, a timer can be started which will display a running tank pressure and time in minutes remaining until the tank is empty. When tank pressure reaches 500lbs or when the tank pressure is zero the application will alert you.

This is not a substitute for looking at the oxygen cylinder gauge to determine actual pressure and should not be relied on as a means to determine oxygen remaining.
