Health Canada just issued a warning for noninvasive ventilation devices. The devices are used to provide noninvasive respiratory support to patients who experience respiratory insufficiency that is caused, for example, by obstructive sleep apnea, chronic obstructive pulmonary disease, and neuromuscular or chest wall disorders.
The therapy has been used, more and more, in the emergency and critical care settings for acutely ill patients. Because of this, Health Canada has expressed its concern about Canadian and international adverse events associated with these devices when they are used as life-supporting ventilators. One reported Canadian case resulted in the patient requiring resuscitation.
Noninvasive ventilation devices can be divided into two groups: Continuous positive airway pressure (CPAP) and variable positive airway pressure (VPAP), also known as bi-level positive airway pressure (BiPAP) ventilators.
Unlike mechanical ventilators that provide life-sustaining ventilation, noninvasive ventilators typically lack a power backup system, alarms, patient monitoring features, and other safety mechanisms that are critical in protecting ventilator-dependent patients against device failure; these are also needed to warn healthcare providers in the event of changes in patients’ health conditions.
To minimize the risk of patient injury associated with noninvasive ventilation devices, Health Canada recommends that:
Any cases of serious or unexpected adverse incidents in patients using non-invasive ventilation devices should be reported to Health Canada at the following address: Health Products and Food Branch Inspectorate HEALTH CANADA Address Locator: 2003D Ottawa, Ontario K1A 0K9. Telephone: The Inspectorate Hotline: 1-800-267-9675. The Medical Devices Problem Report Form and Guidelines can be found on the Health Canada Web site.
