HEAVEN Difficult Airway Criteria: 0 — No HEAVEN criteria. Interpretation: No HEAVEN criteria What to do: No HEAVEN difficult-airway predictors recorded. Inputs: Hypoxemia (SpO2 ≤93% at time of intubation attempt): false; Extremes of size (pediatric or obese): false; Anatomic challenge (trauma, mass, swelling, foreign body): false; Vomit, blood, or fluid in the airway: false; Exsanguination / anticipated massive transfusion need: false; Neck mobility limited (C-collar or intrinsic): false Source: Kuzmack E et al. HEAVEN Criteria: Derivation of a New Difficult Airway Prediction Tool. Air Med J. DOI: 10.1016/j.amj.2017.04.001. PMID: 28739243. Scope: six dichotomous HEAVEN predictors (Hypoxemia, Extremes of size, Anatomic challenges, Vomit/blood/fluid, Exsanguination, Neck mobility issues); presence of any criterion associates with difficult laryngoscopy/intubation in emergency airway cohorts.
