Accuracy drift Meet the requirement for measurement accuracy within 6 hours
* Accuracy applies for respiration rate up to 80 rpm. For respiration rate above 80 rpm, the
accuracy is 4 mmHg or ±12% of the reading, whichever is greater. for EtCO2 exceeding 18
mmHg. 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%.
