Leakage or internal leakage of the sample gas
Mechanical shock
Cyclic pressure which is greater than 10 kPa (100 cmH2O)
Other interference source (if available)
Measurement accuracy may be affected by the breath rate and I/E ratio as follow:
etCO2 is within specification for breath rate 60 bpm and I/E ratio 1:1;
etCO2 is within specification for breath rate 30 bpm and I/E ratio 2:1.
Measurement accuracy is unspecified for breath rate larger than 60 bpm.
