Ultra PC% Cabinet Mount Flowmeters have been recalled by Accutron due to the threat they could pose to patients. 206 units in total may suffer from a defect wherein the oxygen gets turned off but the Nitrous Oxide continues to flow out. This could lead an individual using the item to incur a serious brain injury. Eight models are affected by the recall, and each can be brought back to Accutron in order to obtain a new unit.
