GE Healthcare is warning physicians that some of its ventilators and anesthesia machines may have unresponsive buttons.
The company said the problem affects Engström ventilators and Aespire View, Aisys, and Avance anesthesia machines made between April 23 and July 22. It said buttons on left, right and bottom keypads may not always detect pressure. That could make some menus inaccessible and delay treatment for patients.
The General Electric Co. unit said the devices usually respond if the button is pressed again, but if that doesn't work, users may be able to access the proper function by using the control wheel. If that does not fix the problem, users should stop using the device and contact a GE Healthcare service representative.
The company said it is notifying customers about the problem, and plans to fix all the affected systems at no cost to costumers. It said no injuries to patients have been reported.
