Technical Specifications - ResMed Mirage FX User Manual

• At a fixed rate of supplemental oxygen flow, the inhaled oxygen
concentration varies, depending on the pressure settings, patient
breathing pattern, mask, point of application and leak rate. This
warning applies to most types of CPAP devices.
