Point-of-Care Ultrasound in High-Altitude Illness (HAI): A Lifesaving Tool in Extreme Environments

Video Transcription

Video Summary

This presentation by emergency medicine NP Ari Chaskis explores point-of-care ultrasound (POCUS) in diagnosing and managing high-altitude illnesses: acute mountain sickness, high-altitude pulmonary edema (HAPE), and cerebral edema (HACE). POCUS aids in detecting lung B-lines for pulmonary edema, cardiac function for right heart strain, and optic nerve sheath diameter for intracranial pressure. Benefits include portability, real-time imaging, and greater sensitivity than chest X-rays. Challenges involve battery life, extreme temperatures, and required operator skill. Despite limited research, POCUS is a promising tool for wilderness and expedition medicine, helping early diagnosis and treatment to improve outcomes in remote high-altitude environments.
