Abstract: OBJECTIVE: To determine the diagnostic accuracy of an over-the-counter infant pulse oximeter for cardiorespiratory events. DESIGN: Single-centre prospective diagnostic accuracy study. SETTING: University of Alabama at Birmingham. PATIENTS: Infants weighing ≥1500 g, <44 weeks' postmenstrual age (PMA) and off ventilator/continuous positive airway pressure support. INTERVENTIONS: Test device for 48 hours in addition to standard hospital monitors, ECG and pulse oximetry. MAIN OUTCOME MEASURES: ) <80% for ≥3 s. RESULTS: <80% ≥3 s was 14% and 74%, while the specificity was >99% and 96% for smoothed and raw data, respectively. Sensitivity for bradycardia events was higher for events with longer durations and/or when using higher thresholds. Sensitivity was higher for hypoxaemia events with longer durations and/or when using higher thresholds. CONCLUSION: An over-the-counter infant pulse oximeter had high specificity for bradycardia and hypoxaemia events consistent with a low false alarm rate. Sensitivity improved with longer events and higher event thresholds. TRIAL REGISTRATION NUMBER: NCT05774470.
