This presentation will begin with a refresher on HAI followed by an explanation of using POCUS to diagnose and monitor in these environments. Practical considerations and challenges will be discussed.
  1. Describe key clinical features of high-altitude illness, including acute mountain sickness (AMS), high-altitude pulmonary edema (HAPE), and high-altitude cerebral edema (HACE).
  2. Explain the principles and advantages of point-of-care ultrasound (POCUS) as a diagnostic and monitoring tool in remote, high-altitude environments.
  3. Identify specific POCUS applications relevant to high-altitude illness, such as:
    1. Pulmonary assessment for B-lines in HAPE
    2. Cardiac evaluation for right heart strain
    3. Optic nerve sheath diameter (ONSD) measurement for HACE.
  4. Discuss the practical considerations, challenges, and limitations of using POCUS in austere, high-altitude settings.
  5. Recognize future directions and opportunities for research and technology development that can expand POCUS use in wilderness and expedition medicine.
