Arterial Line Waveform Explained: Placement, Normal Waveform & Pulse Pressure Variation

Understanding the arterial line waveform is essential for clinicians managing critically ill patients in the ICU, emergency department, and operating room. In this Whiteboard Medicine lesson, we break down the fundamentals of arterial line monitoring, including how to place an arterial line, how to interpret the normal arterial waveform, and how to use pulse pressure variation (PPV) to assess fluid responsiveness in mechanically ventilated patients. This video walks through the key physiologic principles behind arterial pressure monitoring so you can better interpret bedside hemodynamics and make smarter resuscitation decisions. 📚 Download the PDF study guide for this video: 👉   / whiteboardmedicine   Patreon members get access to mini-courses, study guides, practice questions, ad-free videos, and in-depth educational discussions designed for emergency and critical care clinicians.
