Clinical Trial Summary
The purpose of this research study is to evaluate the Owlet Smart Sock 3 wireless pulse
oximeter performance in assessing the heart rate and oxygen saturation in neonatal
population, while measuring the same parameter with a standard wired pulse oximeter
simultaneously. The monitoring duration with the study device will be a maximum of 60
minutes, after which the recorded data from the Owlet Smart Sock 3 and the standard wired
pulse oximeters will be de-identified and analyzed.
Description:
This prospective observational study compared the HR and SpO2 measurements of the OSS3
(Owlet, Utah, USA) with the Masimo SET® (Masimo Corporation, California, USA) in infants
admitted to the University of Utah NICU. The inclusion criteria were infants who weighed
1.7-2.5 kg at the time of monitoring and were medically stable to tolerate routine care. The
exclusion criteria were: infants with significant anomalies, congenital deformities, or
medical instability. Infants with an intravenous catheter (IV) and skin lesions on either
foot were excluded from the study. The wireless device being tested was the OSS3. The gold
standard for validating the pulse oximeter's accuracy is arterial blood oxygen saturation
(SaO 2 ) at the pulse oximeter sensor site. [6] However, obtaining SaO2 is an invasive
arterial blood test for infants. To avoid this conflict, the OSS3 was tested against the
reference FDA-approved wired pulse oximeter Masimo.
The study was approved by the University of Utah Institutional Review Board, and informed
consent was obtained from parents. During the measurement, OSS3 and Masimo were placed on the
infants with one device on each foot. Since the data obtained from the study devices can not
be recorded in the hospital electronic medical record, the hospital wired pulse oximeter
(Philips, Amsterdam, Netherlands) continued to be used on one of the infant's hands during
the study period. OSS3 and Masimo were calibrated appropriately against the hospital wired
pulse oximeter with matching HR and SpO 2 readings. Pulse oximetry data were collected
simultaneously for 60 minutes on the quiet infants. The two devices (OSS3 and Masimo)
continuously recorded HR (beats per minute, bpm) and SpO2 (%) every two seconds. Data from
the 2 devices were uploaded and compared according to their time stamped measurements. The
paired data agreement was compared using Pearson's correlation coefficient (r), Bland-Altman,
Average Root Mean Square (ARMS), and Prevalence and Bias Adjusted Kappa (PABAK) analyses.
