Portable, consumer-grade pulse oximeters are accurate for home and medical use: Implications for use in the COVID-19 pandemic and other resource-limited environments.

ABSTRACT:

Objective

To determine the correlation between 3 lightweight portable pulse oximeter devices compared to a standard wall mount pulse oximetry device.

Methods

We performed a single-center, prospective, observational study of 4 pulse oximetry devices, 3 of which are commercially available to the public. A convenience sample of 200 emergency department (ED) patients with chief complaints of cardiopulmonary origin or a peripheral capillary oxygen saturation ≤ 94 percent were enrolled. Analysis of variance was performed to compare SpO2s and test characteristics of the 3 devices compared to control.

Results

Although differences in measured SpO2s were observed (P < 0.001) across groups, the differences were small (mean differences ranged from 1.00% to 1.87%). The corr
