The device is equipped with a patient-gas measure-
ment module (PGM) for O
agent, or with an O
This is a sidestream gas measurement, in which the
sample gas is fed back into the breathing system.
End-tidal measured values are calculated for each
breath from the local maxima and minima of the real-
time measurements during expiration.
All data are standardized to ATPS conditions.
Due to the T
measurement accuracies for O
thetic agent may deviate at respiratory rates of 60 /min
or higher and an I:E ratio of 1:1. The influence of respi-
ratory rate and the I:E ratio on the accuracy has been
verified in a simulated breathing system using a rectan-
gular waveform for the gas concentration.
