Device Use

Hamilton ventilators are used to support adults, children, infants and newborns with breathing. Health care professionals use them during patient transport in or outside hospital settings.

Reason for Recall

Hamilton Medical, Inc. is recalling the HAMILTON-C1, T1, MR-1 ventilators because the capacitators may leak electrolyte fluid onto the ventilator’s control board. If the control board contacts the electrolyte fluid, the control board or installed spare parts could short circuit. As a result of the short circuit, the ventilator may switch to “Ambient State.” 

During the ‘Ambient State’ the ventilator will alarm and display the following on the screen:

A “Realtime clock failure” may also appear on the screen and the user will be notified to set a date and time:

The ‘Realtime clock failure’ will not have severe effects, but the ‘Ambient State’ failure will require immediate action. ‘Ambient State’ may require a health care professional to provide air supply to the patient with a manual resuscitating device and use another ventilator. Serious injury or death may result for patients who do not breathe on their own or do not receive immediate intervention.

There have been zero reported incidents, injuries, or deaths related to this recall.
