If the condensation in the patient circuit is excessive, the use of a heated humidifier may
require the installation of a water trap in the circuit. The water trap prevents any con-
densed water in the patient circuit from running into the patient airways and causing per-
sonal injury.
Any external humidifier connected to the ventilator must comply with ISO 8185 or
80601-2-74.
Any HME connected to the ventilator must comply with ISO 9360.
Do not add any attachments or accessories to the humidifier that are not listed in the
instruction for use of the humidifier or the humidifier might not function correctly
affecting the quality of the therapy or injuring the patient.
The use of an HME or an external humidifier may require readjustment of the ventilator
low-pressure alarm.
Certain HMEs and HCHs are sufficient to provide humidification when the ventilator is
used invasively. Check specific suppliers’ recommended use.
