POCUS for the Critical Care Provider

Stephen Ramsey

PT, DPT, CCS
Point-of-care ultrasound (POCUS) is transforming bedside assessment by allowing critical care providers to evaluate cardiac function, volume status, pulmonary physiology, vascular safety, and muscle integrity in real time. This two-day immersive course focuses on the practical application of ultrasound to assess physiologic readiness, identify causes of clinical instability, and guide safe, informed clinical decision-making.

Participants will develop hands-on skills in lung and diaphragm ultrasound, cardiac assessment, inferior vena cava evaluation, vascular screening for DVT and abdominal aortic aneurysm, and muscle ultrasound for detecting and monitoring critical illness–associated weakness. Dedicated instruction on mechanical circulatory support (LVAD and Impella) will highlight ultrasound’s role in assessing preload, ventricular interaction, and physiologic tolerance.

Emphasis is placed on integrating ultrasound findings into clinical workflow—linking image acquisition to physiologic interpretation and real-world decision-making. Through hands-on labs and case-based integration, participants will learn to use ultrasound as a tool to enhance patient safety, improve clinical reasoning, and monitor physiologic response over time.

Why this course...

Point-of-care ultrasound (POCUS) is rapidly becoming an essential tool in critical care physical therapy, allowing clinicians to perform immediate bedside assessment of cardiopulmonary function, vascular status, and overall physiologic readiness for mobility. For clinicians working in the ICU, ultrasound provides a unique ability to integrate evaluation of cardiac performance, pulmonary pathology, vascular conditions such as deep vein thrombosis (DVT), fluid and volume status, and aortic screening within a single modality. POCUS also supports identification of mechanical circulatory support device positioning and function, while enhancing real-time clinical decision-making.
