🫁 Gupta Postoperative Respiratory Failure/Pneumonia Risk (framework)
The Gupta postoperative respiratory failure and postoperative pneumonia models are two NSQIP-derived logistic regressions with procedure-specific coefficients. This page frames their predictors and links to the official calculators.
Gupta Postoperative Respiratory Failure/Pneumonia Risk (framework)
When to use
Use to identify patients at high risk of postoperative pulmonary complications so preoperative optimization (smoking cessation, treating infection), intraoperative lung-protective ventilation, and postoperative pulmonary rehabilitation can be intensified. Complements the ARISCAT score.
How it works
Two independent NSQIP-derived logistic models. Respiratory failure (ventilation > 48 h or unplanned reintubation): functional status, ASA, preoperative sepsis, emergency surgery, procedure category. Pneumonia: age, ASA, functional status, COPD, sepsis, smoking, procedure category.
Key points
- Because each model carries per-procedure coefficients, precise probabilities require the official calculators rather than an on-platform estimate. (original synthesis · not guideline verbatim)
- The respiratory-failure outcome is defined as mechanical ventilation > 48 h or unplanned reintubation.
- The two models share several predictors (ASA, functional status, sepsis) but pneumonia additionally weighs age, COPD, and smoking.
