The patient underwent an upper endoscopy.When scope was removed in preparation for insertion of an ultrasound probe, the patient became unresponsive with oxygen saturation at 25%.A manual resuscitator was employed to ventilate the patient but the mask was found to have a deflated air cushion.Two additional manual resuscitators were quickly obtained but were also deflated.A resuscitator with an intact air cushion was located and the patient was successfully ventilated.The patient had developed bradycardia (to 30s) - likely secondary to hypercarbia/ hypoxia.This resolved with one dose of epinephrine.The patient was then alert, comfortable and neurologically intact.12-lead ekg was unchanged.A decision was made to cancel the exam.Manufacturer response for manual resuscitator, resuscitation bag foldable adult (per site reporter): the teleflex rep initially advised that since the masks have no expiration date perhaps the hospital should consider replacing unused resuscitators every 6 months.One month later he informed the hospital that the resuscitators actually expire 3 yrs from the date of manufacture and that this date can be determined from the 4 digit lot number - the first 2 digits indicate the year the product was made and the last 2 numbers indicate the week the product was manufactured.
