Philips REMstar Auto A-Flex - Session and Breathing Data; Session and Leak Data; AHI and Breathing Patterns; 90% Pressure Measurement

11User Manual
• Days > 4 - This screen displays the cumulative number of device therapy sessions that exceeded 4 hours over a 7
day and 30 day time frame.
• Large leak - During any given night, the device recognizes the percentage of time the patient was experiencing
what it deemed to be a large leak. Large leak is dened as the level of leak that is so large, it is no longer possible
to determine respiratory events with statistical accuracy. This screen displays the average of these individual nightly
values of percentage of time in large leak over a 7 day and 30 day time frame (provided the device has at least 7 or
30 days of data respectively). If the device has only 5 days of data to use for the calculation, the 5 day average value
will be seen under the 7 day display. If you see a large increase in the percent of time in large leak indicated here,
contact your home care provider for assistance. This screen only displays if your home care provider has enabled it.
• AHI - The device accumulates individual Apnea/Hypopnea indices (AHI) for each session the patient used the
device. This screen displays the average of these individual nightly AHI values over a 7 day and 30 day time frame
(provided the device has at least 7 or 30 days of data respectively). If the device has only 5 days of data to use for
the calculation, the 5 day average value will be seen under the 7 day display. This screen only displays if your home
care provider has enabled it.
• Periodic Breathing - During any given night, the device recognizes the percentage of time the patient was
experiencing periodic breathing. This screen displays the average of these individual nightly values of periodic
breathing over a 7 day and 30 day time frame (provided the device has at least 7 or 30 days of data respectively). If
the device has only 5 days of data to use for the calculation, the 5 day average value will be seen under the 7 day
display. If you see a large increase in the percent of time in periodic breathing indicated here, contact your home
care provider for assistance. This screen only displays if your home care provider has enabled it.
• 90% Pressure - During any given night, the device recognizes the 90% Pressure achieved by the Auto Algorithm.
90% Pressure is dened as the pressure at which the device spent 90% of the session time at or below. For example,
if the device recognized airow for 10 hours, and 9 hours were spent at or below 11 cm H
2
O, and 1 hour was spent
above 11 cm H
2
O, then the 90% Pressure would be 11 cm H
2
O. This screen displays the average of these individual
nightly values of 90% Pressure over a 7 day and 30 day time frame (provided the device has at least 7 or 30 days
of data respectively). If the device has only 5 days of data to use for the calculation, the 5 day average value will be
seen under the 7 day display. This screen only displays if the device was set to Auto-CPAP therapy.
