ASA Class
Functional Status
Emergency Surgery
Sepsis Status (Preoperative)
Type of Surgery
COPD
Gupta Resp Failure Score:
–
Score: 0
Default scoring assumes 0 for un-set fields.
Predicts risk of mechanical ventilation for longer than 48 hrs postop or reintubation within 30 days.
Why Use
May be useful in discussions of informed consent and in managing patient/family expectations perioperatively.
Formula
Postoperative respiratory failure risk*, % = e x / (1 + e x ) Where x = −1.7397 + sum of the values of the selected variables. *Defined as requiring mechanical ventilation >48 hrs after surgery, or unplanned intubation ≤30 days of surgery.

Critical Actions
High risk of postop respiratory failure should not be used as justification for avoiding a necessary operation.
