Thus, notwithstanding their limitations, volitional tests remain on the first line and must be best exploited. Maximum inspiratory pressure (PI,max) is the classic volitional test of inspiratory muscle strength. It is measured as the highest mouth pressure sustained for 1 s during a maximum inspiratory effort against a quasi occlusion. Although simple in principle, the PI,max manoeuvre is difficult for many and requires a hermetic seal around the mouthpiece. As a consequence, low values may be due to true muscle weakness, a submaximal effort, or air leaks in the case of facial muscle weakness. The sniff is an … ER -
