. for the EMS Classroom Dynamic Learning Exercise Pathophysiology Worksheet 1. Define the following terms. Use your book for reference if you have to. Pathophysiology is a founda>onal (yet frequently underemphasized) part of EMT educa>on. Whether understanding a pa>ent presenta>on or reading a NREMT exam ques>on, an understanding of pathophysiology is crucial. This ac>vity can be given out to groups or individuals for use in class or at home to get them into some of the main pathophysiological concepts. It is vital that you facilitate conversa>on and demonstrate the importance of the material. Do you have an interes>ng case that may highlight some of the points below? Amount of blood pumped from the heart (leN ventricle) Vascular resistance Cardiac output Compensa>on Decompensa>on Stroke volume Heart rate x stroke volume The amount of contrac>on of the blood vessels. In discussion relate how cardiac output and vascular resistance = blood pressure. Inadequate perfusion to the >ssues; note how this is different than hypotension. The body’s aWempts to maintain perfusion. This is the point to discuss how the components of heart rate, stroke volume and vascular resistance are used to maintain blood pressure.
