A quantitative analysis of extension and distribution of lung injury in COVID-19: a prospective study based on chest computed tomography

Table 3 Lung volume, gas volume and lung weight calculated for the entire lung parenchyma as well as for each lung aeration compartment (hyper-, normally, poorly and non-inflated)

CT variable	Lung volume (ml)		Lung volume (%)		Gas volume (ml)		Gas volume (%)		Weight (g)		Weight (%)
CT variable	Median	IQR	Median	IQR	Median	IQR	Median	IQR	Median	IQR	Median	IQR
Total lung	2103	1240			1154	1095			919	411
Hyperinflated	500	748	23	30	391	664	35	25	83	89	9	12
Normally inflated	1000	539	47	12	594	380	51	16	285	166	31	18
Poorly inflated	400	246	19	11	143	76	12	13	312	170	34	11
Non-inflated	200	280	11	13	26	12	2	2	239	254	26	18

The latter have been reported as absolute values as well as percentage of the total lung parenchyma. Data are reported as median values and interquartile ranges (IQR)
