Roth Score for Hypoxia Screening
Simple, validated bedside test for detecting hypoxaemia without pulse oximetry. Patient counts aloud from 1 as fast as possible on a single breath. Count-to-20 test: counts ≥20 AND breath-holding time ≥10 seconds effectively rules out SpO₂ <95%. Useful in resource-limited settings.
