ventilatory circuit by the sidestream CO
2
option.

patient data, can damage the equipment, and can void your product warranty.
WARNING Always use accessories according to the standards of your facility
and according to the manufacturer's directions for use.
Note Breath rates greater than 50 breaths/minute may reduce the reported ETCO

values. Select the 175 ml/min flow rate to minimize errors at higher breath rates.
The 175 ml/min flow rate is recommended for intubated adult patients. When
