Abstract : Maximum respiratory pressure-volume relationships were determined in five experienced male subjects by three methods: (1) by exerting pressure against a mercury U-tube manometer; (2) by exerting pressures against an occluded breathing tube with the subject sitting in a full-body plethysmograph; and (3) by maximally exhaling into and inhaling from a series of different-sized containers. Greater expiratory and inspiratory pressures could be exerted against infinite resistance (methods 1 and 2) than against variable resistance (method 3). (Author)
