Yes. The Z1™ uses an advanced algorithm called Z-Breathe™.  Z-Breathe™ has 3 settings: ranging from moderate relief to maximum relief for the expiratory phase of your breathing cycle.  Z-Breathe™ will also learn your breathing pattern and adjust the baseline accordingly. 


There are three Z-Breathe Algorithm settings:

  1. CPAP or APAP–1 Enables the Z-Breathe™ Algorithm at a gentle response rate which adjusts the airflow gradually during the inhalation-exhalation cycle. In this setting, the algorithm will initially adjust rapidly to breathing, but the adjustments will become gentle and gradual after a few inhalation-exhalation cycles.
  2. CPAP or APAP–2 Enables the Z-Breathe™ Algorithm at a medium response rate which adjusts the airflow moderately during the inhalation-exhalation cycle. 
  3. CPAP or APAP–3 Enables the Z-Breathe™ Algorithm at the most aggressive response rate which adjusts the airflow rapidly during the inhalation-exhalation cycle.

To change the Z-Breathe™ Algorithm setting:


For the Z1™ Base CPAP, (the white and gray unit) you will see CPAP-1, CPAP-2 or CPAP-3.

  1. The unit must be in Standby Mode (pressure of “0.0” indicated on the display).
  2. Hold down both the up and down arrow buttons at the same time until you see “CPAP-1” or “CPAP-2” or "CPAP-3" flashing on the display.
  3. Press the up or down arrow buttons until you observe your desired setting on the display (If CPAP-3 is not an option, make sure you have the latest Z1 Firmware.)
  4. To lock- in the setting, hold down the Start/Stop button until the display reads "Accept".
  5. For the Z1™ APAP (the black and gray unit) you will be looking for APAP-1, APAP-2 or APAP-3 flashing on the display.  When you see that follow the steps #3 and steps #4 above to set the Z-Breathe™ setting.
