4.8 Alarm seCngs menu
The alarm seCngs menu allows the user to specify when paent alarms will acvate.
Using the pointers and +/- bu@ons the user can set the alarms to the desired seCng for:
•
CPAP pressure
•
Apnoea delay
•
Maximum respiratory rate
CPAP mode is used as an example.
CPAP pressure
The top scale is used to select the high pressure alarm seCng and the lower scale adjusts the low
pressure alarm seCng. Pressure can be altered in increments of 1cmH20. High and low pressure alarms
can be turned-off by posioning the pointer at the “off” posion.
Apnoea
Monitoring apnoea events proceeds in three phases: Se@ling period, Delay period and Normal breathing.
The apnoea alarm will not acvate during the first 60 seconds of therapy (Se@ling period). If there is an
apnoea event within the last 12 seconds of the se@ling period then the alarm will be reported and
acvated at the 60 second mark (in such cases, there is no subsequent delay period). Acvaon of the
apnoea alarm can be delayed, aGer the 60 second se@ling period, by a further 20 to 60 seconds in
increments of 1 second by adjusng the +/- bu@ons (Delay period). If an apnoea event occurs in the last
12 seconds of the delay period it will be reported at the end of the delay period and the apnoea alarm will
be acvated. The delay period is followed by the normal breathing phase (Normal breathing). During the
normal breathing phase, the apnoea alarm nofies that a breath has not been detected for a period of 12
seconds or greater during acve therapy.
F Max
The respiratory rate is adjusted with the +/- bu@ons in increments of 5 seconds from “Off” to 60 breaths
per minute. When the appropriate alarms seCngs have been set, proceed by pressing the OK bu@on.
