Root Cause
The 'climb high, sleep low' principle is critical above 2,500 m. Ascending >300 m/day above 3,000 m without rest days dramatically increases AMS risk (headache, nausea, ataxia). Kilimanjaro (5,895 m) requires at least 5-7 days on standard routes (e.g., Machame 6-7 days, Lemosho 7-8 days). Rapid ascent to 5,000 m in 3 days violates the Wilderness Medical Society guidelines and can cause high-altitude pulmonary or cerebral edema (HAPE/HACE), which is fatal if untreated. AI may confuse with shorter treks (e.g., Everest Base Camp in 12 days) or underestimate altitude effects.

'高走低睡'原则在2500米以上至关重要。在3000米以上每天上升超过300米且无休息日会显著增加AMS风险（头痛、恶心、共济失调）。乞力马扎罗山（5895米）标准路线至少需要5-7天（例如马查梅路线6-7天，莱莫绍路线7-8天）。3天内快速上升到5000米违反了荒野医学协会指南，可能导致高原肺水肿或脑水肿（HAPE/HACE），如果不治疗会致命。AI可能混淆较短的徒步（例如12天珠峰大本营）或低估海拔影响。

90% success Plan a minimum 7-day itinerary: Day 1-2: 2,700 m (Machame Gate), Day 3: 3,800 m (Shira Camp), Day 4: 4,600 m (Lava Tower, then descend to 3,900 m), Day 5: 3,900 m (Barranco Camp), Day 6: 4,000 m (Karanga Camp), Day 7: 4,700 m (Barafu Camp), Day 8: summit (5,895 m) and descend. Use 'climb high, sleep low' principle.

75% success If forced to do shorter itinerary (e.g., 5 days), include a rest day at 3,700 m (e.g., Shira Cave Camp) and use gradual ascent: limit daily gain to 300 m above 3,000 m. Monitor pulse oximetry; if SpO2 <80% at rest, descend. Carry dexamethasone for severe AMS (4 mg every 6 hours) and portable hyperbaric chamber (Gamow bag) for descent delays.

Dead Ends
Common approaches that don't work:
-
75% fail
Diamox can reduce AMS symptoms but does not prevent HAPE/HACE; it's a prophylaxis, not a substitute for proper ascent rate. Over-reliance can lead to false confidence and ignoring symptoms.
-
90% fail
Persistent headache with nausea is a key AMS symptom; ignoring it can progress to ataxia, HACE, or HAPE. Immediate descent is required, not continued ascent.
-
65% fail
Oxygen is rarely used on Kilimanjaro (unlike Everest) due to logistics; even with O2, rapid ascent without acclimatization still risks AMS. O2 only masks symptoms.
