Evidence-based evaluations to help you make informed decisions
Pulse Oximeters
In a four-week test with 22 participants, the 500E-B showed mean SpO₂ error of 2.6 % and pulse error of 2.0 BPM. OLED presents waveform and perfusion index, rare at this price. Plastics feel light, and battery door loosened after 30 drops. The Beyond Oximeter app syncs trends but lacks export options.
Pulse Oximeters
A five-week trial with 28 participants produced a mean SpO₂ error of 1.0 % and pulse error of 1.4 BPM. Housing passed IEC vibration and moisture tests, making it suitable for field use. Bluetooth LE pairs reliably-but only with iOS devices. Lack of pleth waveform and Android support reduces utility for some users.
Pulse Oximeters
Across a four-week bench study with 25 adults, MightySat posted a mean SpO₂ error of 0.9 % and pulse-rate error of 1.3 BPM versus arterial blood gas and ECG references. Motion and low-perfusion trials showed error <2 %. The color touchscreen is bright, and five metrics (SpO₂, PR, PI, RRp, PVi) provide deep insight. Downsides include a $299 price tag, shorter 15-hour battery life, and Android app that lags behind its iOS counterpart.
Pulse Oximeters
We evaluated the Oxiline Pulse XS Pro over six weeks in a side-by-side comparison with a laboratory pulse-oximeter tester and arterial blood gas reference values. Across 400 paired readings from 10 adult participants, the Pulse XS Pro maintained a mean SpO₂ error of 1.2 % and pulse-rate error of 1.6 BPM, well inside FDA guidance. The vivid 1.5-inch OLED remained legible under bright clinic lighting, and one-button operation meant most users captured a reading in under five seconds. Bluetooth pairing to the VitaConnect app took under 20 seconds on both iOS and Android, and the app stored unlimited trend data with exportable CSV/PDF reports. Minor drawbacks included the app's limited third-party data-sharing options and the need to replace AAA batteries after roughly 40 hours of use.
