Shock can be overwhelming . . . both as a topic to learn about and when caring for a patient suffering from shock.What really helped me understand shock was a video lecture that compared three types of shock (hypovolemic, cardiogenic, and septic) side by side and detailed what is occurring within the body during each one.Now, a few years later and after caring for several patients experiencing each type, I feel that I have a better understanding of this complex disease process.To help the topic click, I created a three page guide.
