Oxygen Concentrator
14
OCSI Sensor
The OCSI sensor detects the oxygen concentration of the air
being delivered to the patient. The sensor consists of an intake
and outlet port on each end of a flow path that is encased in an
air-tight cover. The microprocessor determines concentration
from the OCSI sensor output, and activates alarms when
appropriate. The limits for alarm conditions are programmed
into the software of the microprocessor and are described in
the Warning Alarms section of this manual. The concentrator
takes several minutes to build internal pressure and
concentration. This is known as the warm-up period, and the
signal from the sensor is ignored by the PCB for ten (10)
minutes. This means that the alarms associated with the OCSI
will not activate until this predetermined amount of time has
passed.
Serial Number Identification
The serial number of the CAIRE Companion 5 is located on the
back label of the outer case. The serial number is in the middle
of the label, just below the bar code. A sample label is shown
below.
