2.4 Lung USG (Figure 1)
The scanning for B-lines was done according to the protocol provided
previously by Lichentstein and Targetta in their studies14, 15. We used a 8 or 12 quadrant model depending
upon the height of our patients and the entire thorax was scanned using
7-13 MHz linear probe, Sonosite M-Turbo Platform, (FUJIFILM SonoSite,
Inc, USA) at the mid-clavicular and the mid-axillary lines, as shown in
the figures 1,2. 19-21 The B-lines were semi
quantified and given a score using the LUS scoring scale.22
