Plain-English summary
The NOxBOXi Nitric Oxide Delivery System, model NOXBOX-I, is being recalled over dose fluctuations.
Fluctuations may be more likely to occur if the total flow through the device sensor, which the device uses to determine flow, is less than the minimum device requirement of 0.5 LPM. Dose fluctuations have also been observed when a Bunnell LifePulse HFJV system or conventional ventilators are set to low service pressures generally less than 3.0 PSI, a pressure difference greater than 5.0 cm H2O, or breath-per-minute rates of 300 (5 Hz).
The recall covers 1,667 units, distributed in Tennessee. The device carries model numbers NOXBOXI from the manufacturer and REQNOXBOXI from the US distributor. The FDA has classified the recall as Class I.
Clinicians using the system should follow the manufacturer's instructions and pay particular attention to the flow and ventilator settings identified in the notice.
