剛剛想找高海拔頭痛的文章. 在uptodate裡面並沒有這個章節
(但WMS有)
但看到這段. 順便貼上來

海拔相關的疾病— 非快速動眼睡眠期間呼吸改變，這種現象稱為海拔週期性呼吸，在海拔超過2500 m 時會遇到，並且在海拔更高的地方變得非常常見[17- 19]。它是潮式呼吸的一種形式，反映了睡眠期間由於缺氧（呼吸興奮劑）和低碳酸血症（呼吸抑制）導致的神經訊號變化。週期性的高原呼吸可能發生在海拔低至 1400 m 的地方，但通常不會幹擾睡眠，直到遊客或登山者達到海拔 2750 m 以上。 (請參閱「通氣控制障礙」) 當視網膜小動脈破裂導致血液外滲至視網膜時，就會發生高原視網膜出血[20-22]。視網膜循環發生許多與高原腦循環相同的變化。這種情況在海拔 5000 公尺（16,400 英尺）以上最常見，尤其是從事劇烈活動的人。除非出血延伸至黃斑，否則很少出現症狀。除 AMS/HACE 和 HAPE 之外，高海拔可能會導致或加劇許多疾病（表 4）。例子包括： 長期暴露在高原期造成的問題，例如慢性高山症和高原肺動脈高壓；因缺氧而加劇的原有疾病，如缺血性心臟病；以及在高海拔地區出現的與缺氧無關的病症，例如凍傷和光角膜炎。其中許多條件將單獨討論。 (請參閱「對希望搭飛機或前往高海拔地區的心臟病患者的處理」和「光角膜炎」和「凍傷：急性護理和預防」和「成人意外低溫」)
Other altitude-related illnesses — Altered breathing during non-REM sleep, a phenomenon known as periodic breathing of altitude, is encountered at altitudes over 2500 m and becomes very common at higher altitudes [17-19]. It is a form of Cheyne-Stokes respiration and reflects changes in neural signaling due to hypoxia (respiratory stimulant) and hypocapnia (respiratory depressant) during sleep. Periodic breathing of altitude may occur at altitudes as low as 1400 m but generally does not disrupt sleep until visitors or climbers reach altitudes above 2750 m. (See "Disorders of ventilatory control".) High altitude retinal hemorrhage occurs when there is rupture of retinal arterioles leading to extravasation of blood into the retina [20-22]. The retinal circulation develops many of the same changes seen in the cerebral circulation at altitude. It is most common at elevations above 5000 m (16,400 feet), particularly among those engaged in strenuous activity. Symptoms rarely develop unless hemorrhage extends to the macula. Numerous medical illnesses other than AMS/HACE and HAPE may be caused or exacerbated by high altitude (table 4). Examples include: problems resulting from chronic altitude exposure, such as chronic mountain sickness and high altitude pulmonary hypertension; preexisting medical conditions exacerbated by hypoxia, such as ischemic heart disease; and conditions arising at altitude unrelated to hypoxia, such as frostbite and photokeratitis. Many of these conditions are discussed separately. (See "Approach to patients with heart disease who wish to travel by air or to high altitude" and "Photokeratitis" and "Frostbite: Acute care and prevention" and "Accidental hypothermia in adults".)
