Brachial artery

Blood pressure is defined as a measurement of the force with which blood presses against the wall of a blood vessel. Blood pressure, as popularly used, is the pressure determined indirectly, existing in the large arteries at the height of the pulse wave. When a blood pressure reading is taken, the systolic over diastolic value is determined. Systolic pressure is defined as an aspect of a blood pressure reading which indicates the maximum arterial pressure occurring during contraction of the left…

5. What are the potential contraindications that can prevent someone from having a cardiac catheterization? What is the contraindication that must be considered in Robert Wilson’s case? Why is this of concern? There are potential contraindications to getting a cardiac catheterization, though the only contraindication is the inability to provide an informed consent. There have been unstable patients how have tolerated this procedure but with high risk patients, the nurse has be cautious of…

The force of blood as it circulates against the blood vessel's inner walls is called blood pressure. There are many things affect blood pressure, causing it to rise. * The amount of force with which the blood pumps * The amount of blood in the body * The blood vessel's diameter So that generally, blood pressure rises when the heart pumps harder, there is an increase in the amount of blood in the body, or there is a decrease in the diameter of the blood vessels that carries the blood.…

Volkmann’s Contracture Emily Matherne 12/12/15 A Volkmann’s contracture is a deformity of the hand, fingers, and wrist caused by injury to the muscles of the forearm. Another commonly used name is Ischemic Contracture. This deformity happens when there is a lack of blood flow to the forearm, which occurs when there is an increased pressure due to swelling causing a condition called compartment syndrome. Compartment syndrome can cause a Volkmann’s contracture. Injury to the arm, including…

Question 1. a) “What serosal cavities have been penetrated by the 1st arrow?” The pleural cavity and pericardial cavity have been penetrated by the 1st arrow as they tend to appear in the thoracic cavity on the left side of the chest. b) “Explain the location, the microscopic characteristics of the serous membrane, and the purpose of the serous membrane.” The serous membrane, the peritoneum is located within cavities of the abdomen and the pelvis. Pleura are found in the thoracic cavity…

The Brachial Plexus is a network of nerves that sends signals from your spine to your shoulder, arm and hand. It is a complex network with several divisions and branches to innervate the arm. These injuries can occur in various different ways and are known to cause muscle weakness or loss of motion within the affected arm. Falls, major trauma, and even birthing techniques can all cause this debilitating injury to occur in all ages of people. Ranging fro the C5 to the T1 vertebrae, the brachial…

within the chambers (760). The force applied to the heart’s walls and the pressure in the venous system is blood pressure (793). In determining blood pressure, systolic pressure appears when an artery is stretched to its maximum during contraction of the heart chambers, and diastolic pressure appears when an artery can no longer recoil during relaxation of the heart chambers (794). The top value of blood pressure is the systolic pressure, and the bottom value is the diastolic pressure (794). The…

the severity of the disease, this can cause distal tissues to not be adequately perfused with blood, which can predispose these tissues to complications such as skin ulcers, gangrene, and tissue loss.2 Typically, PVD is diagnosed using the Ankle-Brachial Index (ABI), which uses either…

Introduction: Our modern society is engaged in pursuing a healthy and active lifestyle in order to avoid common health problems such as obesity, high blood pressure, and diabetes mellitus to name a few. Exercise duration, frequency and intensity all are relevant in triggering physiological responses in our bodies. For example, skeletal muscles demand an increase in oxygen and substrates and simultaneously remove carbon dioxide and metabolites (Burton et al., 2004). Furthermore, studies have…

Coronary artery disease (CAD; also more simply referred to as coronary heart disease) is a specific type of atherosclerosis, which is in turn a form of arteriosclerosis (Dulson, Fraser, LeDrew, & Vavitas, 2011). All of these medical conditions entail the same problem, which hinders proper blood flow of oxygenated blood in the arteries: the sclerosis (that is, hardening) of arteries in the circulatory system (Sclerosis [medicine], 2016). Arteriosclerosis is a general term used to describe the…
