MIL-STD-461D - Environmental Test Methods Standards
mmHg - partial pressure in millimeters of mercury
mode- Method of operation.
mode command- A command sent by the Host to put the module into an operating mode.
MS - Mainstream
N
2
O - Nitrous Oxide
N
2
O compensation- Mathematical correction applied to the CO
2
measurement to account for
the effects of Nitrous Oxide on the CO
2
concentration.
non-intubation- The process of removing the tube from a patient’s trachea.
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.
reset- A reset is a module event caused when the receive data line is held in a break condition
for a period of time between 10msec and 500msec.
RE101 - Magnetic Field Emissions Test Standard (MIL-STD-462D)
RR- Respiration rate, typically given in breaths per minute.
RS101 - Magnetic Fields Susceptibility Test Standard (MIL-STD-462D)
RS232 - A type of physical interface standard for use between data communications
equipment and data terminal equipment.
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.
SS - Sidestream
SS components- Parts that comprise an entire sidestream system such as the pump, tubing,
fittings and watertrap.
SS System- An end to end method to measure the patients expired gas by aspirating a gas
sample from the airway and drawing it through a sample line to a measurement device.
sample chamber- The area within a measurement device where the (CO
2
) analysis takes
place.
sample line- A tube, or tubing, used to transport 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
occlude when exposed to water.
