Fig. 4From: Replacement of fluoroscopy by ultrasonography in the evaluation of hemidiaphragm function, an exploratory prospective studyRepeated fluoroscopic measurements of right hemidiaphragm excursion in five consecutive measures of inspiration to full inspiration (to inspiratory capacity, IC) and as a sniff inspiration. During inspiratory capacity inspiration only one recording (the second) was statistically significantly different (p < 0.05) than the other measures. During sniff inspiration two (the second and the third) recordings were statistically different to the others (p < 0.05). Results indicate that reproducibility is lower in sniff inspiration than in inspiration to inspiratory capacityBack to article page
