Functions of
TREND 300
Date, Time
Date and time of the internal clock can be adjusted. The
internal clock has a built-in battery with reserve power
for 8 years without mains connection. You can adjust
the weekdays (Mo thru Su), day (1 till 31), month (1 till
12), year (00 till 99), hour (00 till 24) and minute (00 till
59). The clock serves for indicating the right date, for
the right function of the alarm-clock and for the exact
recording of current events.
Ramp
After each turbine start the computer of
TREND 300
checks whether a softstart-ramp has been program-
med. During the time which you have preset the soft-
start function slowly raises the pressure from 3 hPa
(mbar) up to the pressure prescribed by your physician.
This should ease your falling asleep. Before starting soft-
start
TREND 300
checks the proper fitting of the mask
using the full pressure for the selected time.
Especially if you feel you have not yet got used to the
respiration-therapy the softstart can give you relief.
The delay time of
TREND 300
can be adjusted
between zero (in this case the therapeutic pressure
prescribed is instantly given) and 60 minutes (the
therapeutic pressure prescribed is built-up within 60
min).
To ensure that there is no mask leakage even during the
high therapy pressure a mask test time up to 90 s can
be programmed. This mask test runs under full therapy
pressure before starting ramp and checks whether there
is a leakage.
