The Devilbiss Oxymizer Oxygen Conserver is a clinically proven oxygen-conserving cannula designed for patients requiring supplemental oxygen therapy. Its unique reservoir pendant stores oxygen during exhalation and delivers a concentrated bolus at the start of each breath — significantly reducing oxygen consumption compared to traditional continuous-flow cannulas.

How it Works
Both the pendant- and mustache-style models feature an oxygen-storage reservoir. The reservoir functions similarly in both models.
Pendant Model (P-224)
The reservoir is contained in a hard plastic circle-shaped chamber that rests on a patient’s chest, under their clothing — discreet and comfortable for everyday wear
Mustache Model (O-224)
The reservoir is contained in a chamber in the facepiece that sits directly under a patient’s nose — an alternative for different patient preferences.
Oxygen Conservation
The Oxymizer® can achieve a savings ratio of up to 4:1. It allows you to decrease your patient’s liter flow while providing adequate oxygen saturation.
For example, if a patient requires a 2 lpm setting, the Oxymizer® allows you to lower the flow to 0.5 lpm without compromising oxygenation. This represents an oxygen savings of 75%.
By storing oxygen during exhalation and delivering an enriched bolus on inhalation, the Oxymizer® requires less oxygen than a standard cannula.
