Pulmonary AE/Grade

Description

Atelectasis

 

 0

No opacity

 1

Lamellar

 2

Segmental

 3

Lobar

 4

More extensive than one lobe

Pleural effusion

 

 0

None present

 1

Minimal amounts defined as blunted pleural sinus

 2

Moderate amounts defined as extension to two pleural sinuses but not reaching the level of lung hilum

 3

Large amounts up to and > the level of lung hilum

Signs indicative of heart failure

 0

No signs of heart failure

 1

Enlargement of pulmonary vessels in the absence of other congestive signs (pulmonary effusion and/or cardiac enlargement) was interpreted as suggestive of congestion

 2

Congestive heart failure was diagnosed when dilatation or congestion of pulmonary vessels were present, combined with pleural effusion and/or cardiac enlargement

  1. aAtelectasis was graded based on the extension of the opacity, pleural effusion was graded by the amount, and signs indicative of heart failure were noted collectively.
