Nasal inspiratory pressure: an alternative for the assessment of inspiratory muscle strength?



Nasal inspiratory pressure: an alternative for the assessment of inspiratory muscle strength?



Archivos de Bronconeumologia 47(4): 169-175



Muscle strength is usually assessed thorough the determination of static mouth pressure (PImax). However, since this manoeuvre presents certain problems, alternative techniques have been developed over the last few years. One of the most promising is determination of sniff nasal inspiratory pressure (SNIP). To evaluate SNIP assessment as an alternative for the evaluation of the inspiratory muscle strength. Subjects were consecutively included and assigned to one of three different groups: control , COPD patients (23) and patients with neuromuscular disorders (21). Different maximal inspiratory pressures were determined: (a) dynamic in the esophagus (maximal sniff Pes, reference variable), (b) PImax, and (c).
