How this service works
Gupta 2011 Chest logistic probability of postoperative respiratory failure (mechanical ventilation >48 h after surgery or unplanned intubation within 30 days) from ASA class, functional status, preoperative sepsis, emergency case, and surgery type (hernia reference). Returns logit and estimated_probability_percent. Not a medical device, not a diagnosis, not a ventilator order, and not ARISCAT. Gupta 2011 publishes no low/high cutoff.
Output
Returns a JSON object with two fields: 'logit' (the raw log-odds from the Gupta 2011 Chest logistic regression model) and 'estimated_probability_percent' (the corresponding probability of postoperative respiratory failure — defined as mechanical ventilation >48h after surgery or unplanned intubation within 30 days — expressed as a percentage).
Example use cases
Preoperative risk counseling for elective surgery
“Can you calculate the Gupta 2011 postoperative respiratory failure risk for a patient who is ASA class 2, functionally independent, no sepsis, elective bariatric surgery, not an emergency case?”
High-risk emergency case assessment
“Run the Gupta PRF model for an ASA class 4 patient with septic shock, totally dependent functional status, undergoing an emergency aortic surgery — what's the probability of respiratory failure needing mechanical ventilation?”
Comparing respiratory failure risk across surgery types
“What does the Gupta 2011 model give for postoperative respiratory failure probability for an ASA class 3, partially dependent patient with SIRS who needs elective thoracic surgery versus hernia repair?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/gupta_prfWhen to prefer
Use this endpoint when you need the specific Gupta 2011 Chest logistic regression probability for postoperative respiratory failure using the published five-variable model (ASA class, functional status, sepsis, emergency, surgery type). Prefer this over ARISCAT or other respiratory risk tools when the clinical context specifically calls for the Gupta 2011 model, when inputs are already classified per Gupta 2011 categories, or when you need a validated logit output for downstream computation. Not a substitute for clinical judgment or a medical device.
Side effects
- Missing required query parameters (functional_status, asa_class, sepsis, emergency, surgery) returns a 4xx error
- Invalid enum value for sepsis, surgery, or functional_status returns a validation error
- ASA class integer outside 1-5 may return an error or unexpected result
- Payment not included or insufficient USDC via x402 protocol returns 402 Payment Required
- No interpretation cutoff provided — model outputs probability only, no low/high risk classification
