2.6 Humidification
• Humidification must only be used if this has been prescribed by a
physician.
• When using an external heated humidifier, it should be located below
the Vivo 50 and the patient to prevent injury from accidental spillage.
• During transportation of the Vivo 50, the humidifier must be discon-
nected.
• 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 condensated water in the patient
circuit from running into the patient airways and causing personal
injury.
• When adding or removing a HME (Heat and Moisture Exchanger,
artificial nose) or HCH ((Hygroscopic Condenser Humidifier),
always perform a pre-use test.
• Any humidifier connected to the Vivo 50 must comply with
ISO 8185.
• Any HME connected to the Vivo 50 must comply with ISO 9360.
• The use of an HME or an external humidifier may require readjust-
ment of the Vivo 50 low-pressure alarm.
• Certain HME’s and HCH’s are sufficient to provide humidification
when the Vivo 50 is used invasively. Check specific suppliers’ recom-
mended use.
The Vivo 50 has been tested and validated with the Fisher & Paykel
MR850 heated humidifier.
