Interpretation of Pulmonary Function Tests

In assessing her pre-op risk, she would be a high risk patient from a pulmonary standpoint. Although different authors use different PFT cut-offs for surgical risk assessment, I usually find it convenient to look primarily at two values, the FEV1 and the pCO2. The lower the FEV1, the higher the risk for pulmonary complications of surgery. ................
