This May Ventlab LLC. in Grand Rapids, Michigan, initiated a voluntary recall of resuscitator bags after discovering that the duckbill valve was sticking thereby preventing air to pass through the patient valve. The bags affected could be life threatening if used, as the lack of airflow could result in patient hypoxia and hypoventilation.

The product defect is thought to be due to incomplete curing during the manufacturing process. This error only effects certain lots and the full list of suspected failed lots can be found at:


Manufacturing errors such as incomplete curing are not an unusual failure, however they have dire consequences. There have been 31 reports of delayed medical care due to professionals having to use two or three of the resuscitation devices to assist a patient. There has also be one reported injury due to the defective bags.

Especially when it comes to medical devices, product defects and failures are of the utmost concern. Companies must take immediate action to not only remove the defective product from the market, but also to solve the production error by finding the source of the product defect. When this occurs the manufacturer is often unable to identify the cause of the failure and must consult expert help to pin point the defect source.
