±5% of the reading (0.08% increased in
error for every 1 mmHg if the reading is
more than 38 mmHg)
Accuracy drift Meets the requirements for measurement accuracy within 6 hours
* Accuracy applies for respiration rate up to 80 rpm. For respiration rate above 80 rpm and EtCO

exceeding 18 mmHg, the
accuracy is 4 mmHg or ±12% of the reading, whichever is greater. For respiration rate above 60 rpm, the above accuracy
can be achieved by using the CapnoLine H Set for Infant/Neonatal. In the presence of interfering gases, the above accuracy
is maintained to within 4%.
