Table 2.

Concordance rate between handheld ultrasound device (HHUSD) and high-end ultrasound device (HEUSD) in B-lines detection was expressed in mean ± standard deviation. Concordance rates between the two devices for the dection of pleural effusion and lung consolidations and for inferior cava vein (ICV) assessment were expressed as number and their percentages

Ultrasound findings detected	Concordance between HHUSD and HEUSD
	Total enrolled population	Patients with BMI > 30 kg/m2
B-lines	79.3% ± 17.7	78.9% ± 12.6
Pleural effusion	88.6%	86.5%
Lung consolidations	82.3%	79.5%
Presence/absence of ICV ectasia	88.7%	86.3%
Respiratory excursions of the ICV (> or < 50% of the diameter)	84.9%	85.8%
