Concept explainers
To discuss:
The mathematical relationship between peripheral resistance and vessel radius; why this related to the laminar flow of blood; and why it makes vasoreflexes such a powerful influence on the blood flow.
Introduction:
In order to keep the blood flowing in the artery, the heart must pulsate pressure. This is referred to as blood pressure (BP). The high blood pressure can lead to hypertension, and low blood pressure can lead to hypotension. This can be measured by using a sphygmomanometer. The resistance and pressure affecting the movement of blood or blood flow is called as peripheral resistance. The resistance in blood flow occurs due to the blood viscosity, vessel radius, and vessel length.

This is transmitted by the electrodes to the equipment to be interpreted and is used to diagnose cardiac medical conditions. In case of an abnormal EKG, the second step would be to use a Holter monitor. Questions Where will you place the electrodes when performing and EKG? Why? What are the different lead types, connections, and placements? When you conclude an EKG, what are the different components that you need to observe and confirm before you disconnect the patient?
