Dräger Medical is recalling the Fabius Anesthesia machines due to excessive oil that was not removed at the time of production. Such excess oil may interfere with the position detector of the ventilation motor during operation and may cause ventilation to fail. A halt in ventilation may lead to serious adverse health consequences, including patient injury or death.
