absolute accuracy* Full accuracy mode:
0 to 40 mmHg: ± 2 mmHg
41 to 76 mmHg: ±5% of reading
77 to 150 mmHg: ±10% of reading
ISO accuracy mode: add ±2mmHg to the full accuracy mode
Inaccuracy specifications are affected by the breath rate and I:E. The EtCO

accuracy is within specification for breath rate ≤
60 rpm and I/E ratio ≤ 1:1, or breath rate ≤ 30 rpm and I/E ratio ≤ 2:1.
