Available today is a new firmware update for the Z1™ CPAP with a brand new Z-Breathe™ setting that may provide relief to certain Z1™ users that have experienced large swings in pressure while using the Z1™. The new setting, called ‘CPAP 3’, is the most aggressive setting available for reducing large pressure swings while using the Z1.
Please note: this upgrade is for CPAPs only. DO NOT use it on your Z1 Auto or you will disable the Auto functions and turn your machine into a CPAP only.
We encourage you to experiment with the settings to achieve maximum comfort.
Step 1: If you have not done so you must first download and install the HDM Data Viewer on your PC. Your Z1 has stored all of the sleep data since your first night’s use in its flash memory. Syncing your Z1 with the Data Viewer application will ensure that you do not lose existing sleep data.
Download and install the Z1 Data Viewer.
Step 2: Once the Data Viewer is installed follow the instructions to Sync your Z1. Once your Z1™ has synced, follow the instructions to save your data to file. This will save existing data to your PC to prevent its loss during the firmware upgrade.
Step 3: Download and install the Z1™ Firmware Installer.
Step 4: Once the software is installed, reconnect your Z1™ to the PC and follow the prompts to select your preferred upgrade options. Once you have selected your options complete the firmware upgrade.
About Z-Breathe™ settings…
Typically users experience pressure swings while breathing on a fixed pressure CPAP device. Pressure swings occur as a spike in pressure during exhalation and a drop in pressure during inhalation. Z Breathe is designed to eliminate the spikes and drops while keeping the pressure constant, thereby delivering more comfortable therapy.
Pressure swings can vary between users and this is due to the lung capacity of the person breathing on the machine. Larger individuals will typically have greater lung capacity that will require a more aggressive setting.
- CPAP 1 offers mild pressure swing relief
- CPAP 2 is the Default Setting and offers moderate pressure swing relief
- CPAP 3 is the most aggressive setting for pressure swing relief
