What is a PRO of an Oxymizer?

• A. Inexpensive
• B. Compact
• C. Delivers a wider FiO2 range
• D. Efficient because it uses 25-75% less O2 from source

Answer: (D)

The Oxymizer works by incorporating a reservoir that stores oxygen during exhalation and releases it during inhalation. This means each inhalation can draw from both the stored oxygen and what’s coming from the source, giving a larger effective dose of oxygen without needing to crank up the flow. Because of this reservoir effect, you can often maintain the same delivered FiO2 while using a lower flow from the oxygen source, or achieve a higher FiO2 at the same flow, which translates into less oxygen used from the source overall. That efficiency—saving oxygen by delivering more oxygen with each breath—is the main advantage, and it’s why the pro is stated as using 25-75% less oxygen from the source. The other points (being inexpensive, more compact, or simply widening the FiO2 range) aren’t the defining benefit of the device.
