SpO2 Assistant 3.1 is a PC-based data management tool for Bluetooth/USB pulse oximeters. It allows you to:
Normal oxygen saturation levels typically range between 95% and 100%. Readings below 90% are often considered hypoxemic and may require medical attention. By using SpO2 Assistant, you can keep a digital log of these readings, making it easier to share accurate history with healthcare providers during consultations.

1. For Sleep Medicine Specialists
Obstructive Sleep Apnea (OSA) is notoriously underdiagnosed. SpO2 Assistant 3.1 introduces a Nightly Desaturation Index (NDI) graph. While older versions merely recorded dips, version 3.1 categorizes them by severity (mild: 90-94%, moderate: 80-89%, severe: <80%) and timestamps each event. This allows doctors to correlate oxygen drops with specific sleep stages when used alongside a basic actigraph. Complete Guide to SpO2 Assistant 3
