Percussionaire is recalling its High Frequency Transport Phasitron Breathing Circuit Kits due to a product defect that causes over-pressurization. “There are two parts of the Phasitron kit that must be pressed together during manufacturing,” a [recall notice](https://www.fda.gov/medical-devices/medical-device-recalls/percussionaire-recalls-high-frequency-transport-phasitron-breathing-circuit-kits-over-pressurization?utm%5Fmedium=email&utm%5Fsource=govdelivery) explains. “If one part is angled incorrectly and pressed, the part can become deformed. This causes the PEEP (positive end expiratory pressure) valve to be stuck in the closed position,” which leaves no way to manually release the valve. When the valve is stuck, there is no way to manually release the valve. 

The notice says that using the affected Phasitron kits may cause serious adverse health consequences, including lung injury, low blood pressure, collapsed lung, cardiac arrest, and death. To date, three complaints and one injury have been reported due to the product defect.
