The process repeats with each new heartbeat. The signals that make the heart's muscle fibres contract come from the sinoatrial node, which is the natural pacemaker of the heart. In an ECG test, the electrical impulses made while the heart is beating are recorded and usually shown on a piece of paper. This is known as an electrocardiogram, and records any problems with the heart's rhythm, and the conduction of the heart beat through the heart which may be affected by underlying heart disease. ECG shows how fast the heart is beating, whether the rhythm of the heartbeat is steady or irregular and also the strength and timing of electrical signals as they pass through each part of the heart.
For the Technical Communications Rhetorical Analysis assignment, I have reviewed two instructional documents. The first document is an instructional document for patientsreceiving steroid pulse therapy for the treatment of autoimmune diseases and the effect of instruction on patient knowledge by Yu-Chu Pai who works for BioMed Central Ltd. The second document is also a letter about blood transfusion errors by American Society of Registered Nurses. The purpose of this memo is to outline the similarities and differences that I have discovered during my rhetorical analysis of these two pieces. I will provide an audience analysis and a situational analysis, along with a discussion of the conventions and appeals of the two project proposal documents.Audience
With this knowledge, they were able to more precisely diagnosis certain cardiovascular problems. The electrocardiogram (ECG or EKG) is a diagnostic tool that measures and records the electrical activity of the heart in exquisite detail. Interpretation of these details allows diagnosis of a wide range of heart conditions. These conditions can vary from minor to life threatening. An ECG is a very useful tool for determining whether a person has heart disease.
A cardiologist is a medical professional who concentrates on the state of the patient's heart and other areas which may be connected to it. The treatment of this organ as well as the study and research or its function, is often applied by the doctors to their patients for better results. Equipment and Paraphernalia Doctors of the heart often use medical equipment and other medical paraphernalia to help them pinpoint the closest possible factor that may be affecting the patient. The electrocardiogram is one of the most commonly used equipment that supports the cardiologist in finding what may be wrong with the patient. The electrocardiogram is just one instrument among many that can help distinguish the issues of a certain patient concerning his cardiologic health.
Electrocardiogram Abstract The purpose of Lab twenty-eight was to understand the electrical and mechanical events associated with an electrocardiogram reading: how to interpret the reading of an electrocardiogram under different physical circumstances and how changes in heart rate could be affected by outside sources. Also including, how someone would work the equipment that is used in the lab experiment. The main purpose of the lab though is how to place the four leads and understanding the reading of the electrocardiogram. Introduction Electrocardiograms are used to obtain information about the function of the heart (VanPutte, 2011). An electrocardiogram is a reading of the electrical activity of the heart made from electrodes placed on the surface of the skin (2010, 01).
Physicians use the MRI examination to help diagnose or monitor treatment for circumstances such as tumors of the chest, abdomen or pelvis,certain types of heart problems,blockages or enlargements of blood vessels, including the aorta, renal arteries, and arteries in the legs,diseases of the liver, such as cirrhosis, and that of other abdominal organs, including the bile ducts, gallbladder, and pancreatic ducts,diseases of the small intestine, colon, and rectum,cysts and solid tumors in the kidneys and other parts of the urinary tract,tumors and other abnormalities of the reproductive organs,causes of pelvic pain in women, such as fibroids, endometriosis and adenomyosis,suspected uterine congenital abnormalities in women undergoing evaluation for sterility and breast cancer and implants. How the Test is Performed: You may be asked to dress in a hospital gown or clothing without metal fasteners (such as sweatpants and a t-shirt). Certain types of metal can be unsafe and may cause wrong images.You will lie on a narrow table, which slides into the middle of the MRI machine.
Circulation refers to the flow of blood around the body from the heart to vital organs. In order to ensure adequate circulation, the patient may require the use of one or more intravenous (IV) tubes (Berniker). Through the IVs the patient receives fluids, drugs, and blood transfusions as needed to support circulation. When vital organs fail, the body cannot regulate these components, and must be quickly restored to a normal state by a doctor. Preserving the body’s internal equilibrium requires careful monitoring of innumerable indicators of the patient’s well-being.
Applications: EMG signals are used in many clinical and biomedical applications. EMG is used as a diagnostics tool for identifying neuromuscular diseases, assessing low-back pain, kinesiology, and disorders of motor control. EMG signals are also used as a control signal for prosthetic devices such as prosthetic hands, arms, and lower limbs. Electrical Safety Measurement While isolation physically and electrically separates two parts of a circuit, the two parts can interact. The isolation is achieved by using electromagnetic field coupling between the two circuits.
Check airway maintenance with C spine protection, a nurse must note the skin color, assess conscious level, and chest movement of the patient if the patient unconscious, the medical team should open the airway by using the jaw-thrust maneuver. 2. Check breathing and ventilation, a nurse I should note if the patient is not breathing, call a hospital emergency code and start CPR. (Trauma) 3. Circulation with hemorrhage, a nurse must assess the level of consciousness, such as the Glasgow coma score and AVPU which are “alert, voice, pain and unresponsive” to control hemorrhage, check the radial and carotid pulses, check for another external bleeding.
Nurses educate and assist patients to achieve their competency in caring for themselves. Orem’s theory emphasizes the patient’s self-care needs. These needs are biological, psychological, developmental, and/or social. Thus, the goal of nursing through Orem’s theory is to increase the patient’s ability to independently meet these needs. The common problems that I deal with are musculoskeletal injuries from accidents resulting in fractures, and various forms of arthritis resulting in joint replacement surgeries.
