The following tables provide approximate duration times for B (M-6) and E (M-24) oxygen tanks.
Please note that these figures are only meant to serve as a guide.
Note: Actual tank durations will depend on your actual breathing rate, the initial fullness of the
tank, and other factors such as leaks and gauge accuracy.

Example 1: M6 tank, breaths/minute = 16, flow setting = 3
•
Using table 1, find the breath rate of 16 at the top of the table
•
Move down from 16 until you reach the row for flow setting = 3
•
The approximate tank duration for this example = 5.2 hours
Example 2:E tank, breaths/minute = 18, flow setting = 2
•
Using table 2, find the breath rate of 18 at the top of the table
•
Move down from 18 until you reach the row for flow setting = 2
•
The approximate tank duration for this example = 28.5 hours
