Does the Z1 have a pressure-relief function? How do I adjust it?
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, called CPAP 1/2/3 for the Z1 and APAP 1/2/3 for the Z1 Auto:
- CPAP / 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.
- CPAP/APAP–2 Enables the Z-Breathe™ Algorithm at a medium response rate which adjusts the airflow moderateley during the inhalation-exhalation cycle.
- CPAP/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:
- The unit must be in Standby Mode (pressure of “0.0” indicated on the display).
- 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.
- 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.)
- To lock- in the setting, hold down the Start/Stop button until the “CPAP – X” indicator no longer flashes on the display.
You can also use the Nitelog app to easily change the settings of the Z1 Auto.
