Neftaly Wearable sensors tracking blood oxygen levels during high-altitude training
Neftaly can enhance high-altitude training by integrating wearable sensors that monitor blood oxygen levels (SpO₂), providing real-time insights into an athlete’s acclimatization and performance.

???? Importance of Monitoring SpO₂ at High Altitudes

At elevations above 2,500 meters, oxygen levels decrease, leading to potential hypoxemia (low blood oxygen). Monitoring SpO₂ helps athletes assess their acclimatization, adjust training intensity, and prevent overexertion. Studies indicate that SpO₂ levels can drop significantly during high-altitude exposure, and tracking these changes aids in evaluating the progression of acclimatization and the risk of altitude-related illnesses .Verywell Health MDPI

⌚ Wearable Devices for SpO₂ Monitoring
