- Important in determining risk of:
- Operative mortality
- Postoperative complications
- Postoperative dyspnoea and unacceptable quality of life
- Assessment includes the use:
- Routine lung function tests:
- Spirometry values (FEV1 / FVC)
- Diffusing capacity for carbon monoxide (TLCO)
- Calculated postoperative predicted values using ventilation/perfusion scans or CT evaluation
- Functional assessments (CPET or shuttle walk test)
- Routine lung function tests:
- In changes from previous guidance, specific cut-offs are no longer recommended but used to risk-stratify patients for shared decision making
