Reason for recall

Ventilator coaxial breathing circuit may have, expiratory valve sets with membranes sticking to valve body, not detectable during pre-operative test, which will result in "exhalation obstructed " alarm, which may result in inadequate ventilation, oxygen desaturation. Advising: Prior to use, test lung action. If alarm occurs, expiratory valve set removal to overcome membrane adhesion or replacement

Device recalls are issued when a component, software or design fault could cause the device to fail or give wrong readings. Many are corrections applied in the field rather than physical returns.
