An oxygen conserving device is also available for use with ambulatory oxygen systems. The conserving device works by only releasing oxygen upon inspiration. This avoids any oxygen being wasted during the expiration phase of breathing. This can increase the lifetime of the oxygen system by between three to five times depending on the flow rate.

Conservers therefore allow patients to user smaller, more lightweight oxygen systems and become more mobile whilst on oxygen therapy. They can also reduce the drying irritation which continuous flow oxygen can have on patient's airways.

It is recommended that the device is used in automatic mode. In this mode, the conserver can recognise an increase in respiration rate and deliver a larger 'bolus' of oxygen with each breath. Therefore, when the patient is exercising, oxygen saturation levels are maintained at 90%.
