EPR
In CPAP and AutoSet modes, EPR is designed to maintain optimal treatment for the patient during inhalation and reduce the delivered mask pressure during exhalation. The desired result of EPR is to decrease the pressure the patient must breathe out against, making the overall therapy more comfortable.
The features of EPR are:
You can select the following options for EPR Level: Off, and 1, 2 or 3 cmH2O.
Pressure drop is limited to avoid sub-optimal treatment (maximum drop is 3 cmH2O).
When you enable EPR, the delivered pressure will not drop below a minimum pressure of 4 cmH2O, regardless of the settings.
You can set EPR to Ramp or Full Time.
