Performance of Wearable Pulse Oximetry During Controlled Hypoxia Induction: Instrument Validation Study Background: Oxygen saturation is a crucial metric used for monitoring patients with lung disease or respiratory illness who are at risk of hypoxemia (low blood oxygen saturation). Early and accurate identification of abnormal oxygen saturation is important for these patients, who may develop significant desaturation and hypoxemia symptoms during their daily activities. Objective: This study aimed to evaluate the accuracy of Apple Watch Series 7 and a clinical-grade pulse oximeter, Masimo MightySat Rx, under hypoxemia and to assess whether measurement error is influenced by the oxygen desaturation rate (ODR). Methods: We calculated the ODR of each measurement and conducted a comparative analysis of the displayed oxygen saturation readings from both the Masimo MightySat Rx finger pulse oximeter and Apple Watch Series 7 with arterial blood oxygen saturation (SaO) readings obtained from a blood gas analyzer. Results: Both the Masimo MightySat Rx pulse oximeter and the Apple Watch Series 7 tended to overestimate oxygen saturation. The pulse oximeter readings were more likely to fall within 2% of the acceptable (as specified by Masimo) peripheral oxygen saturation (SpO) error range than the Apple Watch (49.03% vs 32.14%). Notably, both devices had limitations under low oxygen saturation levels (

Integration of Micro-Sensors in Everyday Clothing for Health Monitoring The Future You Can Wear Just picture a basic T-shirt for example which monitors heart rate, breathing, stress and hydration — all without any heavy device. We are redefining health monitoring and disease prevention by integrating micro-sensors in clothing. First, let’s take a closer look at how smart clothing works and why this technology is revolutionizing health monitoring. What Are Micro-Sensors in Clothing?

Imagine a shirt tracking your heart rate, stress, sleep, early signs of illness.https://t.ly/DQsqc
