• Your Z1 is intended to be used with CPAP masks (or connectors) which have vent
holes to allow continuous flow of air out of the mask. When your Z1 is turned on
and functioning properly, new air from the Z1 flushes the exhaled air out through
the mask vent holes. However, when the Z1 is not operating properly (e.g., at low
pressure) or the Z1 is off, insufficient fresh air may be provided through the mask and
the exhaled air may be rebreathed. Rebreathing exhaled air for longer than several
minutes can, in some circumstances, lead to suffocation. This applies to most CPAP
devices. Your health care provider will recommend a mask and air tubing to suit
your needs. The Z1 supports several CPAP mask types including nasal masks, full face
masks, and nasal prongs that meet the ISO 17510-2 standard.
• Do not use your Z1 with a mask unless the Z1 is turned on. Once the mask is fitted,
confirm that air is flowing from your Z1.
• Do not block the vent hole or holes in the mask. Follow the mask manufacturer’s
instructions for proper use of the mask.
• In the event of a power failure or machine malfunction, remove the mask
immediately.
• At low pressures some exhaled gases may remain in the mask.
• Electrocution Hazard – Your Z1 is an electrical device, and as such, you should not
immerse your Z1, Power Supply, PowerShell or Battery in water. Always unplug your
Z1 and its accessories before cleaning (and clean only as instructed in this User Guide)
and make sure your Z1 and its accessories are dry before plugging back in.

Your selected setting for the Z-Breathe Algorithm will be retained in the memory of your Z1 unit
after it is turned off. The currently selected Z-Breathe Algorithm setting will be displayed when the
Z1 is delivering treatment pressure.
Z-Breathe is a proprietary algorithm engineered in the Z1 to smooth out the breathing cycle
while enjoying the benefits of CPAP treatment. Typically users experience pressure swings while
breathing on a CPAP device. Pressure swings occur as a spike in pressure during exhalation and
a drop in pressure during inhalation. Z-Breathe is designed to minimize the impact of spikes and
drops while keeping the pressure constant, thereby delivering more comfortable therapy.
Pressure swings can vary between users due to lung capacity and other factors. For this reason we
have created 3 levels of Z-Breathe to accommodate individual users’preferences:
— 1 offers mild pressure swing relief
— 2 is the Default Setting and offers moderate pressure swing relief
— 3 is the most aggressive setting for pressure swing relief
Programming Ramp Mode
Some users find it comforting to acclimate to CPAP therapy each session. This can be
accomplished by programming the Ramp Mode which allows you to start with a low initial
pressure and gradually increase to the prescribed treatment pressure.
Setting Ramp Time
When the Z1 is in standby mode, press and hold the
Up Arrow Button for approximately 3 seconds until
the “00 MINUTES”value flashes. While it is flashing,
repeatedly press either the Up or Down Arrow
Buttons to increase or decrease the ramp time in 5
minute increments. (Figure 12) Set the ramp time to
“00 MINUTES”to disable the Ramp Mode.
When the desired ramp time value is reached, press
and hold the Start/Stop Button for approximately 3
seconds to save your ramp time setting (this setting
will be saved even when the Z1 is not powered). The
Z1 will return to standby mode. To return to standby
mode without saving the new setting, press and
release the Start/Stop Button momentarily instead of
holding it down.
Starting and Stopping Treatment
1. Press the Start/Stop Button on the Z1 to initiate
treatment using the pre-programmed prescription
setting. The Treatment Pressure Display will show
the actual pressure being delivered at all times. If the
Ramp Mode has been programmed, the ramp start
pressure will be displayed upon pressing the Start/
Stop Button and the indicated pressure will rise as
the Z1 ramps up to prescribed treatment pressure.
If the incorrect pressure is displayed, contact your
health care provider before commencing CPAP
therapy. (Figure 10)

16 17
NOTE: Ramp Time must be set to a minimum of 5 minutes prior to
attempting to program Ramp Start Pressure or the change to Ramp Start
