Pulmonary Testing

Pulmonary Testing
Test Predictive Value Indications
ABG

Predicts poor outcome  if   PCo2 > 45mmHg, although it is not necessarily an absolute contraindication for surgery

Severe COPD

PFT's

predicts post-op course in lung resection

evaluate for optimal bronchodilatation

definition of optimal bronchodilatation:

free of wheezing and peak flow > 80% of predicted or personal best

Anticipate Lung Resection

Undiagnosed or suboptimal control COPD or  Asthma

Chest Radiographs

Many false positives, adds little to clinical evaluation

Known Cardiopulmonary disease, URI
