Plain-English summary

The breathing circuit set, coaxial, 1.80 m, with flow sensor and expiratory valve set, REF 260128, used with HAMILTON-C1, HAMILTON-T1 and HAMILTON-MR1 ventilators, UDI-DI 07630002802963, is being recalled. The action covers 2,560 units from lots 199675 and 199676.

According to the manufacturer, the ventilator coaxial breathing circuit may have a crack in the blue tubing, which is used to deliver fresh gas to the patient. The notice states 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 unrecognised, organ damage. The FDA classified the action as Class I, its most serious classification.

Distribution was nationwide in the United States, in New Hampshire, New York, Connecticut, Pennsylvania, Illinois, Maine, Colorado, North Carolina and New Jersey among other states.

Facilities should identify affected stock using the REF, UDI-DI and lot numbers above, quarantine it, and follow the instructions issued by the manufacturer.
