Interstitial Pulmonary Edema Assessed by Lung Ultrasound on Ascent to High Altitude and Slight Association with Acute Mountain Sickness: A Prospective Observational Study.

Acute mountain sickness (AMS) is a common disease that may have a pulmonary component, as suggested by interstitial pulmonary edema quantified by the B-line score (BLS) on ultrasound (US). This subclinical pulmonary edema has been shown to increase with ascent to high altitude and AMS severity, but has not been prospectively associated with AMS incidence in a large prospective study. This prospective observational study was part of a randomized controlled trial enrolling healthy adults over four weekends ascending White Mountain, California.

Point-of-Care Ultrasound in Austere Environments: A Complete Review of Its Utilization, Pitfalls, and Technique for Common Applications in Austere Settings.

With the advent of portable ultrasound machines, point-of-care ultrasound (POCUS) has proven to be adaptable to a myriad of environments, including remote and austere settings, where other imaging modalities cannot be carried. Austere environments continue to pose special challenges to ultrasound equipment, but advances in equipment design and environment-specific care allow for its successful use. This article describes the technique and illustrates pathology of common POCUS applications in austere environments.
