到達一個固定海拔高度, 如果初期幾天沒有高海拔反應(症狀). 之後才出現的症狀要考慮高海拔反應之外的問題.
CDC寫待滿三天 (after 3 days of arrival at high altitude)沒症狀不會再出現AMS

AMS 通常發生在 1-24 小時內
HAPE 通常發生在 2-4 天

如果症狀在到達特定海拔高度兩天後才出現，且無頭痛、靜止時呼吸困難，以及吸氧後症狀未迅速改善，則臨床醫生應考慮其他診斷。

高海拔肺水腫（HAPE）的發生通常較晚，一般發生在到達高海拔地區後2-4天
CDC-High-Altitude Travel and Altitude Illness(CDC網站)
AMS症狀通常在抵達高海拔地區或攀登至更高海拔後 2-12 小時內出現
在相同海拔沒有繼續上升. AMS 通常會在 12-48 小時內消退。

同一海拔待三天沒有症狀. 不會再出現AMS
Symptom onset is usually 2–12 hours after initial arrival at a high altitude or after ascent to a higher elevation and often during or after the first night. Preverbal children with AMS can develop loss of appetite, irritability, and pallor. AMS generally resolves within 12–48 hours if travelers do not ascend farther.
Symptoms starting after 3 days of arrival at high altitude and without further ascent should not be attributed to AMS
筆記 2023 High Altitude Pulmonary Edema(Archived)-Jacob D. Jensen
HAPE typically occurs 2 to 5 days after arrival at altitude.
2013NEJM
AMS 通常在上升到海拔2500公尺以上, 6-12小時之後發生。

HAPE 高海拔肺水腫發生率 0.01-15% (在同樣海拔上升速率, 比 HACE 高). 通常在到達高海拔之後 2-4 天發作.
Initial symptoms typically appear two to four days after arrival at a new altitude.
Initial symptoms typically appear two to four days after arrival at a new altitude.
在同一海拔如果已經適應三天以上沒症狀, 不會再出現 AMS.
