Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents with progressive dyspnea at rest, non-productive cough, and significant exercise intolerance following rapid ascent to [insert altitude] meters over [insert time] hours. Associated symptoms include chest tightness, orthopnea, and generalized fatigue. No history of pre-existing cardiac or pulmonary disease.
Clinical Examination Findings
Vitals: Tachycardia, tachypnea, and peripheral oxygen saturation (SpO2) of [insert value]% on room air. Physical Exam: Auscultation reveals bilateral crackles (rales), predominantly in the right middle lobe initially, progressing to diffuse. Presence of cyanosis, tachycardia, and signs of pulmonary hypertension (e.g., loud P2). No peripheral edema noted.
Treatment Protocol
Immediate descent to a lower altitude is the definitive treatment. Administer supplemental oxygen to maintain SpO2 >90%. Pharmacotherapy: Nifedipine 20mg extended-release every 8 hours. Consider phosphodiesterase-5 inhibitors (e.g., Sildenafil) if descent is delayed. Monitor for neurological deterioration (HACE).
