This study aims to assess the accuracy and stability of smartwatches in predicting acute mountain sickness (AMS).
In locations exceeding an altitude of 2500 m, a cohort of 42 subjects had their Lake Louise AMS self-assessment score, blood oxygen saturation (SpO), heart rate, and perfusion index measured using smartwatches, with the data seamlessly conveyed to the Huawei Cloud.
A significant decrease in SpO was observed in individuals positive for AMS compared to those negative (< 0.05), with the mild AMS group exhibiting significantly lower SpO levels than the non-AMS group (< 0.05). Furthermore, SpO emerged as a significant, independent predictor of AMS [=-0.086, < 0.01, OR (95% CI) = 0.92 (0.87-0.97)], indicating that each unit increase in SpO decreases the probability of AMS occurrence by 8.6%.
The Huawei smartwatches have demonstrated efficacy in diagnosing and foretelling AMS at elevations exceeding 4000 m, showcasing significant reliability and high precision in SpO measurement
本研究旨在评估智能手表在预测急性高原病（AMS）方面的准确性和稳定性。
在海拔超过2500米的地区，42名受试者使用智能手表测量其路易斯湖AMS自我评估分数、血氧饱和度（SpO）、心率和灌注指数，并将数据无缝传输至华为云。
与AMS阴性者相比，AMS阳性者的SpO显著降低（<0.05），轻度AMS组的SpO水平显著低于非AMS组（<0.05）。此外，SpO是AMS的一个显著独立预测因素[=-0.086，<0.01，比值比（95%可信区间）=0.92（0.87-0.97）]，表明SpO每增加一个单位，AMS发生的概率降低8.6%。
华为智能手表已证明在海拔超过4000米时对AMS具有诊断和预测效果，在SpO测量方面显示出显著的可靠性和高精度
