Atrial Fibrilation is described by Mayo Clinic as “an irregular and often rapid heart rate that commonly causes poor blood flow to the body.” “During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly — out of coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation symptoms often include heart palpitations, shortness of breath and weakness. Episodes of atrial fibrillation can come and go, or you may develop atrial fibrillation that doesn't go away and may require treatment. Although atrial fibrillation itself usually isn't life-threatening, it is a serious medical condition that sometimes requires emergency treatment. It can lead to complications.
Stroke Awareness Health Assessment The self-risk assessment I chose to complete was about strokes. A stroke occurs when blood supply to the brain is temporarily interrupted or disturbed. Being that the brain requires a constant flow of oxygen any interruptions could prove to be fatal. The two types of strokes are Ischemic or hemorrhagic. An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically.
Sometimes other signs and symptoms precede sudden cardiac arrest. These may include fatigue, fainting, blackouts, dizziness, chest pain, shortness of breath, weakness, palpitations or vomiting. But sudden cardiac arrest often occurs with no warning. Unlike other muscles in the body, which rely on nerve connections to receive the electrical stimulation they need to function, the heart has its own electrical stimulator — a specialized group of cells called the sinus node located in the upper right chamber (right atrium) of the heart. The sinus node generates electrical impulses that
Coronary artery disease is the leading cause of death for both men and women in the U.S. When the coronary arteries become partially blocked or clogged the result becomes coronary artery disease. Therefore this blockage limits the flow of blood from the coronary arteries, which are the major arteries supplying oxygen-rich blood to the heart. When the heart is working harder and needs more oxygen the coronary arteries expand. Here are a few examples of when the arteries expand, when a person is climbing stairs, exercising, or having sex.
Dysfunction of the chest wall 3. Dysfunction of the lung parenchyma and 4. Other causes. Decreased respiratory drive Decreased respiratory drive may occur with severe brain injury, large lesions of the brain stem (multiple sclerosis), use of sedative medications, and metabolic disorders such as hypothyroidism. These disorders impair the normal response of chemoreceptors in the brain to normal respiratory stimulation.
INTRODUCTION Stroke or brain attack is the sudden loss of neurological function caused by an interruption of blood flow to the brain. Stroke is the third leading cause of death. There are two type of stroke commonly affected among people. A. Ischemic Stroke - Is the most common type affecting individuals - Lack of blood supply to the brain can be caused by thrombosis or embolism. It also may due to a hemorrhage.
Coronary Artery Disease (CAD) or also referred to as Coronary Heart Disease (CHD), a heart disease that develops when your coronary arteries, the major blood vessels that supply your heart with blood, oxygen and nutrients become damaged. CHD is a term used commonly for buildup of plaque in the hearts arteries that could lead to heart attack. Cholesterol containing deposits, also known as plaque on your arteries is to blame for CAD. With CAD, the plaque starts to first grow in the coronary arteries until blood flow to the heart’s muscle becomes limited, in other words, ischemia. It could be chronic and is caused by the narrowing of the coronary artery and limitation of blood supply to part of the muscle.
CLD results from lung injury to newborns who must use a mechanical ventilator and extra oxygen for breathing. The lungs of premature babies are fragile and are easily damaged. With injury, the tissues inside the lungs become inflamed and can break down causing scarring. This scarring can result in difficulty breathing and increased oxygen needs. Some of the causes of lung injury include the following: •prematurity - the lungs, especially the air sacs, are not fully developed •low amounts of surfactant (a substance in the lungs that helps keep the tiny air sacs open) •oxygen use (high concentrations of oxygen can damage the cells of the lungs) •mechanical ventilation - the pressure of air from breathing machines, suctioning of the airways, use of an endotracheal tube (ET tube - a tube placed in the trachea and connected to a breathing machine) Who is affected by chronic lung disease?
In addition to this, the connections between affected nerve cells deteriorate. As the disease progresses, it spreads and affects cells in other parts of the brain. Day to day memory problems are first noticed but other symptoms include not knowing the right words anymore, problem solving, decision making or 3 dimensional perception. * Vascular dementia is caused when the brain is deprived of oxygen. This happens when the arteries which carry oxygenated blood to the brain can't get there and the brain, or part of it, dies.
Read more about the symptoms of pressure ulcers. How pressure ulcers develop Pressure ulcers can develop when a large amount of pressure is applied to an area of skin over a short period of time. They can also occur when less pressure is applied over a longer period of time. The extra pressure disrupts the flow of blood through the skin. Without a blood supply, the affected skin becomes starved of oxygen and nutrients and begins to break down, leading to an ulcer forming.
