Article Synopsis
- Recently developed wearable monitoring devices aim to measure arterial oxygen saturation (So₂) for potential use in aerospace, but their effectiveness in flight conditions is not yet confirmed.
- An initial study involved 10 healthy subjects in a normobaric chamber at varying oxygen levels, comparing readings from a standard pulse oximeter and four wearable devices during different states of body motion.
- Results showed that all wearable devices frequently missed readings during slight to moderate motion, with significant discrepancies in So₂ reporting, indicating they may not be reliable alternatives to traditional p oximeters in flight settings.
