3.3 Diaphragm ultrasound characteristics (Table2, 3)
The diaphragm excursion (DE) decreased from baseline to the PS period
and recovered quickly after extubation even though the values continued
to remain lower than the baseline in both the groups. The two groups did
not show any significant difference between the diaphragm excursions or
in the thickness. The left diaphragm thickening fraction (DTF) was
significantly reduced in group 1 as compared to group 2(13.71 % vs
25.26 %, p=0.035) during PSV.
