If you find the initial sensation of pressure uncomfortable
while trying to fall asleep you may use the RAMP therapy
delay timer. The Polaris EX CPAP system has an adjustable
RAMP therapy delay timer feature that allows the air
pressure in your mask to gradually increase (ramp) until the
set therapy pressure is delivered. If your physician prescribes
RAMP therapy, your home healthcare provider will initially
set the adjustable RAMP timer either for 0, 5, 10, 20 or 30
minutes.
If you feel that you are no longer getting relief from your
initial symptoms of Obstructive Sleep Apnea (OSA), consult
your physician.
How SoftX Works
NOTE: For this procedure, refer to FIGURE 4.1.
SoftX is an innovative technology that makes breathing easier
and more comfortable for the user by decreasing the pressure
that the patient MUST exhale against, while maintaining a
substantially constant positive airway pressure (CPAP). By
tracking the user’s breathing, SoftX is able to determine the
end of inhalation. As the user stops breathing in, the flow of
air from the Polaris EX CPAP is redirected away from the
breathing circuit and mask. The duration of expiratory
pressure rise is minimized with SoftX, allowing the user to
exhale in a more natural, comfortable fashion. Pressure
returns to set therapy and stabilizes prior to the beginning of
the next breath.
The Polaris EX CPAP has three (3) SoftX comfort settings.
These three (3) settings allow the user to adjust the extent of
the pressure drops, with the highest setting resulting in the
greatest drop in pressure. This allows the user to choose the
amount of pressure relief that offers them the greatest level of
comfort.
