Question

does the postural positioning of patients affect their respiratory function?

Answer 1

Answer:

PEmax, and PImax were found to increase in upright positions in healthy subjects [3, 23, 24, 46, 48, 50, 51] and in those with lung diseases [31, 46, 47]. This may be related to changes in lung volumes with positions. Standing and sitting have been shown to lead to the highest lung volumes [72, 73].
