UMD: Pulmonary resuscitators designed to provide respiratory support to a patient by manually squeezing a bag. These resuscitators typically consist of a polymeric (e.g., resilient rubber) self-refilling bag, a nonrebreathing valve to prevent patients from rebreathing their own carbon dioxide. an adapter that has an outlet appropriate to fit any standard mask (22 mm in diameter) or attach to an endotracheal or tracheostomy tube (15 mm in diameter), and an oxygen inlet valve. Some include an oxygen reservoir and/or accept positive end-expiratory pressure valves. Manual pulmonary resuscitators are mostly used during emergencies involving pulmonary arrest or for ventilated patient transport.,SPN: A manual emergency ventilator is a device, usually incorporating a bag and valve, intended to provide emergency respiratory support by means of a face mask or a tube inserted into a patient's airway.
