Gupta Postoperative Respiratory Failure Risk

Description

Calculates the percentage risk of postoperative respiratory failure (mechanical ventilation > 48h or unplanned reintubation) based on the Gupta et al. (2011) model. This calculator uses five preoperative predictors: procedure type, ASA status, functional dependence, sepsis, and emergency status.

Usage

gupta_respiratory_failure_risk(procedure_type, asa_class, functional_status,
                               emergency_case, sepsis_status)

Arguments

procedure_type	String. Surgical procedure category. Valid options include: "anorectal", "aortic", "bariatric", "brain", "breast", "cardiac", "ent", "foregut_hepatopancreatobiliary", "gallbladder_appendix_adrenal_spleen", "hernia_ventral_inguinal", "intestinal", "neck_thyroid_parathyroid", "obgyn", "orthopedic", "other_abdominal", "peripheral_vascular", "skin", "spine", "thoracic_non_cardiac", "urology", "vein".
asa_class	Numeric. ASA Physical Status Classification (1-5).
functional_status	String. Preoperative functional status. Options: "independent", "partially_dependent", "totally_dependent".
emergency_case	Numeric (0 or 1). Is the surgery an emergency? (1 = Yes).
sepsis_status	String. Preoperative sepsis category. Options: "none", "sirs", "sepsis", "septic_shock".

Value

A list containing:

Respiratory_Failure_Risk_Percent

The estimated probability of postoperative respiratory failure.
