Function Description Oxylog 1000
3.6 Pressure Sensor
During ventilation, the pressure sensor controls and switches the stenosis
and disconnection of the patient.
The pressure sensor comprises two diaphragms. The ventilation pressure
acts on the undersides of the diaphragms. The supply pressure (Insp.) is cen-
tered on the craters on the pressure sensor during the inspiration phase. The
built-in mechanical springs in the pressure sensor exert different forces on
the diaphragms:
– Non-adjustable spring force (10 mbar)
– Spring force adjustable (30 mbar to 60 mbar) with the alarm control valve
One or other of the diaphragms is raised according to the respective compen-
sation pressures on the mechanical springs.
