Monitoring lines are lines intended to channel samples of gases to determine EtCO2 during critical and surgical situations. The line makes the connection between a sampling port and a capnograph.

Designed for manual ventilation of the patient. They can be connected directly, or via an extra limb, to the manual ventilation port of the anaesthesia ventilator.

Hydrophobic Disc Filters protect a capnometer from moisture carried in the patient’s exhaled breath.
