Reason for Recall

Ventilator coaxial breathing circuit may have a crack in blue tubing, which is used to deliver fresh gas to the patient. The crack will compromise inspiratory and expiratory flows, leading to partial or complete rebreathing of exhaled gases, which could lead to acute hypercapnia, respiratory acidosis, and if unrecognized organ dysfunction.

Firm Action

Starting on 6/26/2025, recall notices were emailed to customers who were asked to do the following: Return affected devices. If one of the affected breathing circuits would be already in use with a patient, it is requested to exchange it and discard the product after replacement.
