Altitude Sickness Pathology, Prevention & Emergency Protocols
Acute Mountain Sickness (AMS)
Caused by rapid ascent without adequate physiological acclimatization to reduced barometric pressure and hypoxic environment.
- Throbbing frontal headache
- Nausea, anorexia, fatigue
- Insomnia & peripheral dizziness
High-Altitude Pulmonary Edema (HAPE)
Excessive hypoxic pulmonary vasoconstriction leading to elevated pulmonary capillary pressure and fluid leakage into the alveolar airspaces.
- Dyspnea (shortness of breath) at rest
- Persistent dry cough progressing to pink frothy sputum
- Cyanosis (blue lips/fingers), tachycardia, gurgling rales
High-Altitude Cerebral Edema (HACE)
Severe hypoxia impairs cerebral autoregulation and blood-brain barrier permeability, causing intracranial fluid accumulation and swelling.
- Truncal ataxia (loss of motor coordination, inability to walk heel-to-toe)
- Altered mental status, confusion, apathy
- Hallucinations, progressive stupor, and coma
Evidence-Based Acclimatization Guidelines
1. The 300–500 Metre Sleeping Rule
Above an altitude of 3,000 metres (9,840 ft), your sleeping elevation should not increase by more than 300 to 500 metres per 24-hour period. While you can climb higher during the daytime ('Climb High, Sleep Low'), always return to a lower staging camp to sleep.
2. Mandatory Rest Days
Take a mandatory rest day without elevation gain every 3 to 4 days, or for every 1,000 vertical metres gained. This allows renal compensation to balance bicarbonate loss and stabilize arterial blood pH.
3. Hydration & Caloric Metabolism
High respiratory ventilation in cold, dry alpine air leads to significant insensible fluid loss. Maintain a fluid intake of 3.5 to 5 litres daily. Ensure high carbohydrate intake, as carbohydrates require 10% less oxygen to metabolize than fats.
4. Golden Rules of High Altitude
- Any sickness at altitude is altitude sickness until proven otherwise.
- Never ascend with symptoms of acute mountain sickness.
- If symptoms worsen or fail to improve, descend immediately.
- Never leave a sick climber alone.
