Apap - Hoffrichter CPAP User Manual

APAP

(only point 2 AutoCPAP)
In APAP mode (Automatic Positive Airway Pressure), the point 2 automatically
controls the therapy pressure in relation to the respiratory events occurring. The
device is equipped with a special sensor system that can reliably distinguish
between obstructive apnea (airways are closed) and central sleep apnea (respi-
ratory arrest with open airways). Obstructive apnea can be corrected with an
automatic increase in pressure. Central sleep apnea automatically results in a
drop in pressure.
Hypopnea (fl ow reduction, snoring) results in a rise in pressure with a lower
speed. Normal respiration results in a slow drop in pressure.
The maximum values to which the pressure level may rise or fall are specifi ed
by the selection of settings. The device commences therapy once switched on
with the starting pressure, which is likewise adjustable.
