Starting And Stopping Treatment; Choosing Between Z-Breathe Settings; Programming Ramp Mode - Human Design Medical Z1 CPAP System User Manual

General Status Display
In Standby Mode, this display field alternates between a display of the current date, the current
function mode and the Z-Breathe setting . During treatment and while setting treatment
parameters, this display field shows the currently selected function mode (CPAP) and Z-Breathe
setting (1, 2 or 3) . The General Status Display field may also give notification of certain events
which will NOT prevent prevent the Z1 from operating normally but may need to be addressed
by the user .
FAULT
"FAULT" is displayed if one of several conditions has occurred that require your attention . See Fault
Conditions (page 19) for explanations of the FAULT codes .
REMINDER
"REMINDER" is displayed if there is excessive air leakage . See Reminder Alert (page 18) for an
explanations of REMINDER conditions .

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)
CAUTION (When using the PowerShell Only): Make sure your Battery is fully
charged before commencing CPAP therapy using the PowerShell . The battery life
of a fully charged Extended Life Battery in the PowerShell is typically 8 . 9 hours or
longer and treatment will terminate when the charge is expended . To recharge
the Battery, see "Charging Battery" .
2 . Press the Start/Stop Button a second time to stop treatment .

Choosing Between Z-Breathe
The Z-Breathe setting of 1-3 is indicated by the number following
the CPAP designation on the LCD screen . For example CPAP-3
means the CPAP mode with a Z-Breathe setting of 3 (Figure 11) To
set the Z-Breathe setting, press and hold down the Up Arrow Button
and Down Arrow Button simultaneously while in the Standby
mode (pressure of "0 . 0 " indicated on the display) . Once you see the
Function Mode indicator flashing on the LCD screen, you can select
the desired Z-Breathe setting using the Up Arrow Button and Down
Arrow Button . After you have made your selection, press and hold the Start/Stop Button to save it .
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 .
