Results
Fifty patients were eligible for inclusion, but consent
was not obtained from 3 patients, and 7 patients were too
restless to record thoraco-abdominal movement, so 40 patients
were included (Table 1). There were more males than females and more surgical subjects, half of whom
underwent cardiothoracic procedures. The most frequent
cause of respiratory failure was hypoxia (19 subjects).
There were no statistically significant differences between
mask and HFNC in pH, PaO2
, PaCO2
, mean blood
pressure, and heart rate (Table 2). HFNC significantly decreased
breathing frequency (P .001) and significantly
improved MCA/VT (P.001) and phase angle (P.047).
Results of stepwise multiple regression analysis showed
that no items were associated with improved MCA/VT.
Likewise, no items independently affected the improvement
of phase angle.
