Discussion
HFNC improved thoraco-abdominal synchrony, asshown by statistically significant improvement of MCA/VT and phase angle, and decreased the breathing frequency.
This is the first quantitative investigation of the shortterm effects of HFNC on thoraco-abdominal synchrony in adult subjects with mild to moderate respiratory failure.
While Sztrymf and colleagues reported how HFNC affects thoraco-abdominal synchrony, they did not quantitatively evaluate the effects.19 Using MCA/VT and phase angle, which are superior to other indices for quantitatively assessing breathing pattern,21,22 we evaluated thoracoabdominal synchrony.
