Breath detection
Adaptive threshold, minimum 1 vol% change in CO
2
concentration.
Respiration rate
0 to 150
± 1 bpm. The respiration rate I displayed after
three breaths and the average value is updated every
breath. (Measured at I/E ratio 1:1 using breath simulator
according to EN ISO 80601-2-55 fig. 201.101.)
Fi and ET
FiCO
2
and EtCO
2
are displayed after one breath and have a
continuously updated breath average.
The following method is used to calculate end-tidal (ET)
values:
- The highest concentration of CO
2
during one breathing
cycle with a weight function applied to favor values closer
to the end of the cycle.
EtCO
2
will be within specification for all respiration rates
up to 150 bpm. (Measured at I/E ratio 1:1 using breath
simulator according to EN ISO 80601-2-55 fig. 201.101.)
Probe 2-9 channel NDIR type gas analyzer measuring at 4-10 μm.
Data acquisition rate 10 kHz (sample rate 20 Hz / channel).
Pressure, temperature and full spectral interference
correction.
Calibration No span calibration required for the IR bench.
Warm-up Time < 10 seconds (full accuracy)
Rise time (@ 10 l/min)
≤ 90 ms (measured @10 l/min with gas concentration steps
corresponding to 30% of total measuring range for each
gas)
Total system response time < 1 second (Measured according to EN ISO 80601-2-55)
