Resumo(s)
This study aimed to describe diaphragm ultrasonography (DU) during mouth occlusion pressure (P0.1) and maximal inspiratory pressure (MIP) in healthy participants. Four participants performed: (i) neurophysiological tests and then (ii) simultaneous DU with P0.1 and MIP. Diaphragm excursion was 2.37 cm (median) during tidal volume of 0.74 L. Additionally, a median diaphragm excursion of 1.25 cm was associated with a median P0.1 of 1.39 cm H2O, while a median diaphragm excursion of 3.10 cm was associated with a median MIP of 125.88 cm H2O. DU showed a hold-back movement during P0.1 and a plateau during MIP, providing novel insights into diaphragm movement with potential clinical practice implications.
