O Compensation - Mathematical correction applied to the CO
2
measurement to account for
the effects of Nitrous Oxide on the CO
2
concentration.
O
2
- Oxygen.
O
2
Compensation - Mathematical correction applied to the CO
2
measurement to account for the
effects of oxygen on the CO
2
concentration.
Pressure Broadening Compensation - Mathematical correction applied during CO
2
calculation
to account for the effect that barometric pressure has on CO
2
molecule distribution.
Pump - The device used by the Module to aspirate the CO
2
sample from the patient.
RE101 - Magnetic Field Emisions Test Standard (MIL-STD-462D).
Reset - A Module event caused when the receive data line is held in a break condition for
between 10 and 500 msec. After the reset, the Module returns to its EEPROM default
settings and starts up in the standby mode. The Module can respond to host
communication 2 seconds after a reset.
Reverse Flow - A condition that causes a positive pressure on the Module’s exhaust pneumatics
or CO
2
outlet port, where the flow direction is opposite of expected.
RR - Respiration rate, typically given in breaths per minute.
RS101 - Magnetic Fields Susceptibility Test Standard (MIL-STD-462D).
RS232 - Physical interface standard for use between data communications equipment and data
terminal equipment.
Sample Chamber - The area within a measurement device where the (CO
2
) analysis takes
place.
Sample Line - A tube, or tubing, used to transport a patient’s expired gas to the monitor or CO
2
inlet port.
Secondary Shutoff Pellet - A small device used in the internal pneumatics designed to inhibit
flow when exposed to water.
Self Reset - The Module returns to its original state due to a condition other than a watchdog
timeout.
Sensor Fault - An error associated specifically with the CO
2
sensor.
Sensor Signal - The output of the CO
2
bench or CCap.
