(Class B).
CO
2
– Carbon dioxide, a byproduct of cellular metabolism; the majority is eliminated by the
lungs.
CO
2
main processor board- The printed circuit board with electronic components, not
including peripheral devices such as the pump, manifold or pneumatic reservoir.
CO
2
sensor- The device used to detect and measure the level of carbon dioxide concentration
in a gas sample.
CO
2
waveform – The graphical representation of carbon dioxide concentration over time.
CCITT/CRC code- The program code used to derive a cyclical redundancy checksum table
used to verify error free data transmission.
cannula- a device, or tubing, used to deliver oxygen to a patient orally or nasally. Some types
are divided to deliver oxygen through one tube, and aspirate CO
2
through another tube.
capnogram- a graphical display of carbon dioxide concentration over time
capnography-The measurement with numerical display of carbon dioxide concentration, or
partial pressure, appearing at the patient’s airway.
configuration command- Communication protocol command used by the Host system to
temporarily modify specific module settings for measurement criteria. The commands usually
include specific data within the command structure.
configuration response- The module’s reply to a configuration command from the Host
system. It also represents the module’s receipt of the command.
CRC- Cyclic Redundancy Check- An error-detecting code generated from a polynomial that
can be added to a data record or message.
DCOM- Welch Allyn OEM Technologies’ DOS based communication software for the Duet
module.
desflurane compensation- Mathematical correction applied to the CO
2
measurement to
account for the effects of Desflurane on the CO
2
concentration.
differential pressure transducer- An electronic device that converts a non-electrical
parameter into an electrical signal. A differential transducer has two inputs and produces an
output signal that is a function of the difference between the inputs. It is used together with a
fixed resistance across the inputs to measure gas flow.
EEPROM- Electrically Erasable Programmable Read Only Memory
EN864 - Medical electrical equipment- Capnometers for use with Humans- Particular
requirements
ETCO
2
-The measured carbon dioxide value at the end of an exhaled breath.
ETCO
2
Monitor- A device that provides a numeric and or graphical display of the end tidal
CO
2
value.
