Pediatric Asthma Severity Score (PASS)

Description

Calculates the Pediatric Asthma Severity Score (PASS), a clinical tool used to assess the severity of asthma exacerbations in children (ages 1-18). The score evaluates three physical exam findings: wheezing, work of breathing, and prolongation of expiration. Scores correlate with the decision to admit or discharge.

work_of_breathing	String. Use of accessory muscles and retractions. "normal_mild": Normal or mildly increased (0 pts). "moderate": Moderate (1 pt). "severe": Severe (2 pts).
