Table 1.

Definition of the Pulmonary Involvement (PI) score and the Pulmonary Consolidation (PC) score.

PI score
(involvement for each lobe)
PC score
(consolidation of total lung)
Absent 0 A
25 % 1 B
26−50% 2 C
51−75% 3 D
76 – 100 % 4 E

PI score calculator: giving the score to each lobe, the total is the sum of the involvement of the different lobes from 0 to 20.

PC score calculator: considering the total lung, the score is the total of consolidated lung with respect to the total lung.
