The Saudi Food and Drug Authority would like to warn all healthcare practitioners within healthcare facilities from using Breathing Circuits used with Life Pulse High-Frequency Ventilators manufactured by Bunnell



The Saudi Food and Drug Authority would like to warn all healthcare practitioners from using some affected lot ( attached ) of  Breathing Circuits used with the Life Pulse High-Frequency Ventilator manufactured by Bunnell. 

SFDA has become aware through the international regulatory resources, that the heater wire insulation of the breathing circuit - Disposable Patient Circuits-  manufactured by Bunnell- can melt, which  may cause a shortage that creates sparks and smoke in the circuit near the humidifier cartridge , leading to potential adverse events of  burns ,  injuries, lung infections or low oxygen levels in the patient’s blood – god forbid -

Saudi Food and Drug Authority encourages that all healthcare practitioners to adhere to the following :

- Identify any affected  product in your inventory and contact Saudi Food and Drug Authority .

- If you choose to use the affected product, Bunnell recommends that you perform the following actions to reduce the likelihood of this problem occurring :

1-  Visually inspect the circuit and the internal heating wire for thermal damage  every 30-60 min (e.g., sections of exposed wire without insulation, melting, or substantial discoloration). In particular, examine the red wires near the humidification chamber.

2-  Replace the circuit if a "Circuit Low Temp" alarm unexpectedly activates and the low temperature condition is not resolved within 5 min after following appropriate troubleshooting as described in the operator's manual.

3-  Replace the breathing circuit if displayed temperature is noted to be below the set temperature for >5 min.
