Understanding Oxygen Delivery

Lightweight Only Matters If It Meets Your Oxygen Needs

The OxyGo FIT Plus delivers a measured pulse of oxygen in response to inhalation. It offers settings 1 through 4 and does not supply continuous-flow oxygen.

Pulse settings are not equivalent to liters per minute of continuous flow. Your healthcare provider must determine whether the FIT Plus meets your oxygen requirements, including during sleep.

If your prescription requires continuous flow, ask about models such as the Oxlife Liberty 2.
