Chalut 2000 Preschool Respiratory Assessment Measure (PRAM)
Chalut 2000 Preschool Respiratory Assessment Measure (PRAM): five caller-assigned items — oxygen_sat_points (0/1/2), suprasternal retractions (0/2), scalene contraction (0/2), air_entry (0-3), and wheezing (0-3). magent sums only (max 12) and does not auscultate or measure saturation. Score only; no invented mild/moderate/severe bands. Not a diagnosis and not the Westley 1978 croup score.
