Different measures of ventilatory efficiency in preoperative cardiopulmonary exercise testing are useful for predicting postoperative complications in abdominal cancer surgery.

ABSTRACT:

Background

Ventilation as a function of elimination of CO₂ during incremental exercise (VE/VCO₂ slope) has been shown to be a valuable predictor of complications and death after major non-cardiac surgery. VE/VCO₂ slope and partial pressure of end-tidal carbon dioxide (PetCO₂) are both affected by ventilation/perfusion mismatch, but research on the utility of PetCO₂ for risk stratification in major abdominal surgery is limited.

Aim

We aimed to determine the correlation between VE/VCO₂ slope and PetCO₂ measured during preoperative cardiopulmonary exercise testing (CPET) and its association with major cardiopulmonary complications (MCPCs) or death following oesophageal and other major abdominal cancer
