🫁 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.
Because each model carries per-procedure coefficients, precise probabilities require the official calculators rather than an on-platform estimate. (original synthesis · not guideline verbatim)

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.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
