Product Recall Resuscitation Set – Mapleson C System with APL Valve (ICN 1839)

Important Customer Notice Recall

Ref: 2022/1839 ICN Number: 1839


NHS Supply Chain Reference: 54



  • Armstrong Medical has issued a Field Corrective Action Notice following reports indicating that there are a small number of devices in the field associated with Resuscitation Sets that may contain APL valves that do not function as intended.
  • This could lead to indirect patient harm such as a delay in treatment or could possibly lead to a serious deterioration in the health of a patient.
  • Each device is expected to be subjected to a “Before use, verify flow patency” test before clinical use. This is to ensure that the APL valve performs as intended in the closed cap and open cap positions of the valve, ensuring that the reservoir bag inflates (cap position closed) and collapses (cap position open). Such a pre-use test is mandated in the Instructions for Use supplied with the device.
  • In instances where the device is to be made available to use in emergency situations, Armstrong Medical suggest that all devices are subjected to pre-use tests prior to being made available for use in critical care situations or emergency service vehicles.
  • This Field Safety Notice (FSN) is published to facilitate a manufacturing lot specific device recall. See Table 1 for detail of all lots of finished medical devices that are subject to recall under this FSN.
