Absolute Pressure Transducer - A device that converts a nonelectrical parameter, pressure,
into an electrical signal. The ambient pressure transducer on the Module is used to
measure either ambient barometric pressure or the internal bench pressure during
pump operation.
Advisory - Least serious type of fault message. Usually indicates casual user intervention
required.
ASCII - American Standard Code for Information Interchange
ATPD - Ambient Temperature and Pressure, Dry Gas. Describes the gas conditions when the
measurement was taken.

with minimal user or host intervention. In autorun mode, the Module does not revert
to standby mode during a watertrap removal.
Background CO
2
- Level of carbon dioxide present in the environment in which a CO
2
measurement is taken.
Balance Air - The remainder in a specific concentration of mixed gases.
Barometric Pressure - The pressure caused by atmospheric conditions.
Baseline Compensation - A mathematical correction used to account for the effect of low level
gas mixing during inspiration.
Bench - See Capnography Bench.
bpm - breaths per minute
Breath Data - The breath rate results, derived from the breath algorithm, supplied by the Module
