可助聽、睡眠呼吸中止症通知！Apple Watch和AirPods Pro 2推全新健康功能
Apple宣布已獲得衛福部的醫療器材許可，即日起正式在台灣推出Apple Watch睡眠呼吸中止症通知功能；以及AirPods Pro 2提供端對端聽力健康體驗，包括臨床驗證的非處方「助聽」功能。不過並非所有的Apple Watch都支援此功能。
睡眠對健康相當重要，但根據估計，全球有超過10億人受到睡眠呼吸中止症影響，患者在睡眠期間會短暫停止呼吸，使身體無法獲得足夠的氧氣。然而大多數情況未曾被診斷。
那麼Apple Watch如何偵測睡眠呼吸中止症呢？當睡眠期間正常呼吸模式中斷時，Apple Watch的加速計會偵測使用者手腕中與此相關的微小動作。每30天，Apple Watch會分析「呼吸障礙」數據，如持續顯示疑似中度至重度睡眠呼吸中止症的徵兆，便會通知使用者，以便使用者與醫師討論後續處理方式，包括可行的診斷與治療。
