Mallinckrodt Manufacturing LLC is recalling its one-way valve, 22F x 22M, a single-use device accessory used to prevent backward flow of nitric oxide gas into the airways, due to devices not opening properly, which prevents or reduces the flow of ventilated air or oxygen.
The use of the one-way valve, 22F x 22M may cause serious adverse health consequences, including interruption in ventilation which may delay delivery of nitric oxide gas, according to a safety notice from the US Food and Drug Administration. This delay could lead to bradycardia in neonatal or pediatric patients. For all patients, interruption in ventilation may lead to insufficient oxygen in the blood resulting in respiratory failure and death.Â
There have been two complaints and no reports of injuries or death.
The US Food and Drug Administration has identified this as a Class I recall, the most serious type of recall.

The Mallinckrodt Manufacturing one-way valve, 22F x 22M is part of the INOmax delivery system, which delivers nitric oxide (INOmax) therapy gas into the tubes between the ventilator and patient airway (breathing circuit). The one-way valve is used to prevent backward flow of nitric oxide gas into the INOmax DSIR injector module. The omission of one-way valve can also result in high nitric oxide delivery to the patient. The intended prevention of the backward flow and higher-than-prescribed drug delivery applies to both high-frequency ventilators and spontaneous mask setup.
On Aug 8, Mallinckrodt Manufacturing sent all affected customers an Important Medical Device Advisory.
The letter requested customers to:
- Determine if your facility has any of the impacted lots.
- Return only the one-way valves from the affected lot numbers to Mallinckrodt Manufacturing. Use the enclosed FedEx Label to return the one-way valve(s) and the Customer Response Form.
- Send the Customer Response Form to [email protected] even if your facility has no product to return.
If a one-way valve from an affected lot is currently in use on a patient and working as expected, Mallinckrodt Manufacturing instructs customers to not remove it from the circuit and continue to monitor the patient’s oxygen saturation levels.
Health care professionals and consumers may report adverse reactions or quality problems they experienced using these devices to MedWatch: The FDA Safety Information and Adverse Event Reporting Program using an online form, regular mail, or fax.
