acute mountain sickness 急性高山病 AMS
high altitude cerebral edema 高海拔腦水腫 HACE
2001年 NEJM High altitude illness
這段寫的是AMS發生時間, 如果在同樣海拔三天後才出現的症狀, 且與典型 HACE 症狀沒有吻合, 例如缺乏頭痛症狀. 補充水分或休息能快速改善. 或治療(下降.氧氣.類固醇)之後症狀沒有緩解等等. 可能要想想是否罹患其他疾病
Many conditions mimic acute mountain sickness and high-altitude cerebral edema. The onset of symptoms more than three days after arrival at a given altitude, the absence of headache, a rapid response to fluids or rest, and the absence of a response to descent, oxygen, or dexamethasone all suggest other diagnoses. Table 1 lists conditions sometimes confused with acute mountain sickness and high-altitude cerebral edema.

STATPEARLS 在 2019-12-17 有一篇高海拔肺水腫 HAPE 研究提到HAPE的發生率, 文中數字部分沒有另外標明引用的出處, 不過與我底下以前念過的文章有相同的數值, 應該是引用同一篇研究.
海拔 4500 公尺, 發生率 0.6%~6%
海拔 5500 公尺, 發生率 2%~15%, 上升速率快, 發生率高
HAPE復發率 60%
改善體適能無法降低 HAPE 發生率
HAPE 治療後死亡率 11%, 未治療死亡率 50%
HAPE 患者有 50% 同時罹患急性高山病 AMS
HAPE 患者有 14% 同時罹患高海拔腦水腫 HACE
Epidemiology
The severity of HAPE will depend on multiple factors including altitude, initial recognition and management, and access to medical care. At 4500 meters the incidence is 0.6% to 6%, and at 5500 meters the incidence is 2% to 15%, with faster ascent time correlating to a higher incidence. Those with a prior incidence of HAPE have a recurrence rate as high as a 60%. One’s level of fitness is not proven to be a protective factor. Mortality rate, when treated, can be as high as 11% and as high as 50% when untreated. Up to 50% of cases may have concomitant acute mountain sickness (AMS), and up to 14% will have concomitant high altitude cerebral edema (HACE).
要注意的是, 隨著絕對海拔與上升速率, 高海拔疾病的盛行率會有很大差異.

AMS 通常在上升到海拔2500公尺以上, 6-12小時之後發生。海拔越高,嚴重度及盛行率越高。沒有做高度適應的人,海拔2500公尺發生率 10-25%, 但症狀通常輕微,在海拔4500-5500公尺發生率50-85%. 且可能病倒。

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.
HACE 高海拔腦水腫 發生率 1-2%. 通常會合併嚴重AMS 或 HAPE.

Abstract
BACKGROUND:
Acute mountain sickness (AMS) is a pathophysiological symptom complex that occurs in high-altitude areas. The incidence of AMS on Jade Mountain, the highest peak in Taiwan (3952 m), has been reported to be ∼36%. There is a lack of data in children trekking at altitude in Taiwan. The purpose of this study was to determine the incidence, risk factors and symptoms of AMS in children trekking on Jade Mountain, Taiwan.
METHODS:
This prospective cohort study included a total of 96 healthy non-acclimatized children aged 11-12 years who trekked from an elevation of 2600-3952 m in 3 days. The Lake Louise AMS score was used to record symptoms associated with AMS.
RESULTS:
AMS were reported in 59% of children trekking on Jade Mountain over a 3 day period. AMS incidence increased significantly with increasing altitude. The most common AMS symptom was headache, followed by fatigue or weakness, difficulty sleeping, dizziness or lightheadedness and gastrointestinal symptoms. Children who had experienced upper respiratory infection (URI) within the 7 days before their trek tended to have a greater risk for development of AMS. AMS incidence did not significantly differ according to gender, recent acute gastroenteritis, menstruation and body mass index.
CONCLUSIONS:
The incidence of AMS in children trekking on Jade Mountain is greater than that observed in adults, and was associated with altitude and recent URI
