As the exhalation port serves to eliminate CO2from the breathing circuit, its position should be placed as near the patient as possible to more effectively capture the CO2 exhaled by the patient and to decrease the chance of CO2 being washed up into the breathing circuit.
Exhalation ports ensure a quiet ventilation environment enhancing your sleep apnea therapy and oxygen supply. The side port is for oxygen inflow and can be sealed if no oxygen is used.
