OXYGEN TANK DURATION & FILL TIMES

Knowing how long your portable oxygen cylinders will last is very important before you leave your home.  Planning is essential to make sure you do not run out of oxygen while away! 

For patients using conserver devices:

Below are links to duration charts that are based upon the use of a conserver device by the average users breathing frequency; actual duration times may change based upon your breathing frequency.  Most people breathe more frequently when they walk or get other types of exercise, so be aware that exercise usually reduces the time your tanks will last.  If you breathe more than 20 times per minute your tanks will not last as long as the charts say.  Alternately, if you breathe less than 20 times per minute they may last longer.
