HealthRankings Verdict

Nonin Model 3230 — Best for Children with Asthma — Pediatric Accuracy + Alarm

The Nonin 3230 with its pediatric finger sensor is the most accurate pulse oximeter for children with asthma — critical since children's oximetry is notoriously prone to motion artifact from crying and fidgeting. Nonin's PureLight technology maintains accurate readings in pediatric patients. Bluetooth to the Nonin Connect app with customizable alarms for SpO₂ and heart rate makes it ideal for parents monitoring children during asthma attacks.
