Oxygen Cylinder Duration - TAV® Mode
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.
Please note that TAV® flow setting 4 does not support a breath rate higher than 25 bpm and TAV®
flow setting 5 does not support a breath rate higher than 20 bpm.

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 = 1.0 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 = 5.7 hours
•
The approximate tank duration for this example = 6.3 hour
