Measurement accuracy may be affected by the breath rate and I/E ratio as follow:
• etCO
2
is within specification for breath rate ≤ 60 bpm and I/E ratio ≤ 1:1;
• etCO
2
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.
