Hamilton Medical AG

When the ventilator enters the ambient state, alternative ventilation must be provided immediately.

Action taken

On 03/25/19, the firm, Hamilton AG, issued Medical Device Field Safety Corrective Action notices to customers via certified mail with receipt response. Customers were advised that if ventilators entered the ambient state, they should provide alternate ventilation immediately. In addition, in order to exit the ambient state, you must turn off ventilator power.
