- W4366247949 abstract "Monitoring heart rate (HR) and oxygen saturation (SpO2) in infants is essential in the neonatal intensive care unit. Wireless pulse oximeter technology has been advancing but with limited accuracy data on preterm infants. This observational study compared HR and SpO2 of the wireless Owlet Smart Sock 3 (OSS3) to the wired Masimo SET (Masimo) pulse oximeter in preterm or <2.5 kg infants. Twenty-eight eligible infants were enrolled. They weighed between 1.7 and 2.5 kg and were without anomalies or medical instability. OSS3 and Masimo simultaneously monitored HR and SpO2 for 60 minutes. The data were aligned by time epoch and filtered for poor tracings. The agreement was compared using the Pearson's correlation coefficient, the Bland-Altman method, average root mean square (ARMS), and prevalence and bias adjusted kappa (PABAK) analyses. Two infants' data were excluded due to motion artifacts or device failures. The corrected gestational age and current weights were 35 ± 3 weeks and 2.0 ± 0.2 kg (mean ± standard deviation), respectively. Over 21 hours of data showed that HR was strongly correlated between the two devices (r = 0.98, p < 0.001), with a difference of -1.3 beats per minute (bpm) and the limit of agreement (LOA) -6.3 to 3.4 bpm based on the Bland-Altman method. SpO2 was positively correlated between the two devices (r = 0.71, p < 0.001) with a SpO2 bias of 0.3% (LOA: -4.6 to 4.5%). The estimated ARMS of OSS3 compared with Masimo was 2.3% for SpO2 in the 70 to 100% range. The precision decreased with lower SpO2. A strong agreement (PABAK = 0.94) was between the two devices on whether SpO2 was above or below 90%. OSS3 provided comparable HR and SpO2 accuracy to Masimo in preterm or <2.5 kg infants. Motion artifacts, lack of arterial blood gas comparisons, and lack of racial and ethnic diversity are the study limitations. More OSS3 data on the Lower HR and SpO2 ranges were needed before implementing inpatient use.· Pulse oximeters are vital for monitoring preterm infants' HR and SpO2 levels.. · Limited data exist on the accuracy of the wireless OSS3 on preterm infants.. · This observational study found that the OSS3 is comparable to the Masimo SET in measuring HR and SpO2 in preterm or <2.5 kg infants.." @default.
