the decay rate of inspiratory muscle pressure ( pmusi ) was measured during the postinspiratory period of zero flow ( tez ) occurring under a discontinuous inspiratory elastic load with the following tests , ( a ) voluntary changed breathing frequency ( f ) at similar end-inspiratory muscle pressure ( pmusei ) , ( b ) as above plus dead space , hence greater pmusei , ( c ) breathing spontaneously through a dead space or during exercise to obtain different f at similar pmusei .
