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: Data were time aligned and analysed using MATLAB. The coprimary outcomes were the diagnostic accuracy of the test device for the detection of events with heart rate (HR) <50 beats per minute (bpm) and events with oxygen saturations (SpO2) <80% for ≥3 s.
Results: 66 infants with a median gestational age of 31 weeks (range 23-40) were studied at a median 35 weeks' PMA (range 32-42) weighing 1930 g (range 1500-3605 g) from April to July 2023. The sensitivity for detection of HR <50 bpm ≥3 s was 6% and 39% for smoothed and raw data, respectively, while the specificity was >99% for both smoothed and raw data. The sensitivity for SpO2 <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.
期刊介绍：
Archives of Disease in Childhood is an international peer review journal that aims to keep paediatricians and others up to date with advances in the diagnosis and treatment of childhood diseases as well as advocacy issues such as child protection. It focuses on all aspects of child health and disease from the perinatal period (in the Fetal and Neonatal edition) through to adolescence. ADC includes original research reports, commentaries, reviews of clinical and policy issues, and evidence reports. Areas covered include: community child health, public health, epidemiology, acute paediatrics, advocacy, and ethics.
