Overview

Patients with altitude sickness may have a positive history of underlying lung disease and substances or conditions that interfere with acclimatization. Common symptoms of altitude sickness include headache, dizziness, fatigue, cyanosis.

History

High Altitude Categories:

Classification Altitude(mts) Altitude(feet)
High altitude 1,500-3,500 mts 4,921-11,483 feet
Very high altitude 3,500-5,500 mts 11,483-18,045 feet
Extreme altitude 5,500-8,850 mts 18,045-29,035 feet

Patients with altitude sickness may have a positive history of:

  • Substances (alcohol) or conditions that interfere with acclimatization
  • Comorbidities that interfere with respiration such as neuromuscular disease or pulmonary hypertension
  • Sleep apnea
  • Chronic obstructive pulmonary disease (COPD)
  • Restrictive lung disease
  • Cystic fibrosis
  • Pneumonia
  • Pulmonary hypertension
  • Carotid artery surgery or neck radiation

Symptoms

  • Common symptoms of altitude sickness include:[1][2]
    • Headache
    • Dizziness
    • Tinnitus
    • Breathlessness
    • Palpitations
    • Sleep disturbance
    • Fatigue
    • Anorexia
    • Mental confusion
