Portable Volume Ventilators

This equipment is designed to assist breathing in intubated patients (patients whose breathing tube is internal, usually inserted down the throat.) Unlike many of the other kinds of medical equipment, ventilators are life-sustaining devices and are classed by the FDA as Level 3 devices. They can run on AC power, on the internal rechargeable battery, or on an external battery. Ventilators should receive full preventive maintenance at least once a year or after 6000 hours of use, whichever comes first. An internal counter tracks the hours of usage, and usage can be read from the patient pressure meter on the front panel. Vents can only be serviced by manufacturer-trained technicians.

Disposable circuits are interchangeable between all devices: use RP312142, Airway Circuit Kit with tubing & assorted masks, for non-intubated patients only (and normally only for BiPAP and CPAP). There is also a wide variety of alternative airway circuits, masks, and adaptors for use with all ventilators.


Humidifers can be added to the circuit lines of all ventilators by inserting a small piece of circuit tubing (usually comes in 18" lengths) between the ventilator and the humidifier chamber, and then attaching the patient circuit to the other outlet of the chamber (see illustration).   

Available Fisher & Paykel Humidifiers:


designed specifically for homecare hookups with ventilators dual mode-both heated and non-heated wire system capability


neonatal and intensive care applications, special-order only; more sophisticated than HC500, has gas temperature digital display, dual servo control.  Requires an airway temperature probe (i.e. #TR900MR571) to maintain proper air temperature.


constant flow applications such as oxygen therapy and CPAP, special-order only

All Fisher Paykel humidifiers can use the single-use HC335 Adult Humidification Chamber (FSHC335);  there are also reusable humidification chambers available which can be autoclaved and reused.

Optional accessories: Airway temperature probes, reusable heater wire assemblies
