ABSTRACT:
A manual resuscitator is disclosed, comprising a plenum chamber, a pressure chamber communicating with the plenum chamber via a main inflow valve, and a cylindrical chamber within the pressure chamber, communicating with the pressure chamber via holes in the cylinder wall. The plenum chamber receives ambient air or has oxygen-enriched air flowing through. An outflow tube leads from the pressure chamber to a patient connector. The cylindrical chamber houses an adjustable platform for adjusting the volume of the chamber via a threaded volume adjustment rod. A balloon inside the cylindrical chamber is sealingly connected to an external bulb. The outflow tube includes a Puritan Bennett valve modified to function as a Fink valve, and includes a connection for a P.E.E.P. system.
