Fundamentals of IO Access

In emergencies, rapid vascular access can make the difference between delayed treatment and immediate intervention. When intravenous access is difficult or impossible, intraosseous (IO) access provides a fast and reliable alternative. In this course, you'll learn how IO access works, when it should be used, and how to perform it safely in real clinical situations. Through clear explanations, clinical insights, and step-by-step instruction, we'll explore IO physiology, insertion sites, equipment, procedural technique, and troubleshooting. Designed for paramedics, nurses, physicians, and healthcare students, this course gives you the knowledge and confidence to use IO access effectively when every second matters.
