Clinical Decision Making Pathophysiology: Cerebrovascular Accident (CVA) A cerebral vascular accident (CVA) is defined as “a sudden loss of brain functioning from a disruption of blood supply to a part of the brain causing temporary or permanent loss of movement, thought, memory, speech, or sensation”(Belleza, 2016, p. 1). CVA is categorized as ischemic or hemorrhagic.…
If this blockage persists for more than a few minutes the brain cells may begin to die and serious damage can be done. Due to this, immediate medical treatment must be taken to minimize brain damage and potential complications. Ischemic stroke can be caused by various diseases. The most common problem is the narrowing of the arteries in the neck or head, often caused by atherosclerosis.…

A stroke is caused when there is an interruption of blood flow to the brain. This interruption of blood flow deprives the brain of the oxygen and glucose that it needs to function (Lewis, Dirksen, Heitkemper, Bucher, & Camera, 2011). It is essential to get a stroke patient the proper…
If there is an air embolism in the brain it resembles a stroke which can cause confusion, partial paralysis, and some loss of sensation. If an air embolism is present in the lungs it can cause irregular breathing, a lack of oxygen in the body tissue, and also unconsciousness. More severe symptoms include shock and even death. Diagnosing an air embolism is simple because there would have had to been a situation that would have cause it. If you are in surgery or even after surgery and experience symptoms, a doctor may conclude an air embolism.…
The blood carries nutrients and oxygen is pumped from the heart to the brain through the arteries. The faulty blood flow results in brain cells damage or death. Around 85% of strokes are ischaemic stroke as an effect of blood clot. However, the rest of 15% of strokes are haemorrhagic that could be either Intracerebral haemorrhage (ICH) a bleed within the brain or Subarachnoid haemorrhage (SAH) a bleeding on the brain caused by a ruptured blood…
On the John Hopkins website a section called the health explains the effects of stroke. It describes the effects of a stroke, and states that they will vary from person to person as characteristics such as type, location, age, severity, number of previous strokes etc, are different in each person. As the brain is divided into three main areas, the content is broken down into sections explaining the effects to each section such as, what effects can be seen with a stroke in the cerebrum, the effects of a right hemisphere stroke in the cerebrum etc. This text is obliging to someone who wishes to learn about the effects of a stroke in greater detail relating to the brain, in all this text will be very useful for future assignments as it explains, concentrating on the brain, the effects one will…
The neck is a complex part of the human anatomy. In addition to supporting the head, it serves as a conduit of blood flow and nerve impulses between the brain and the rest of the body. In spite of this essential function, it's highly vulnerable to injury, particularly the carotid and vertebral arteries. The carotid artery is close to the surface of the neck and can be injured by blunt trauma. Both the carotid and vertebral arteries can be injured by rapid or violent motions of the neck or when it's hyper extended.…
A stroke is a “brain attack” that anyone and everyone is susceptible to. It occurs when blood flow to an area of the brain is restricted and the brain cells are deprived of the necessary oxygen. This results in cell death and usually a permanent disability. Strokes are one of the leading causes of disability in the United States which is unbelievable since eighty percent of them are preventable. An expert in this field is Professor David J Hanson who is Professor Emeritus of…
Secondary injury is usually the result of hypoxic-ischemic injury caused by cerebral edema. Because the soft and pliable brain is enclosed within the rigid skull, abnormal brain fluid dynamics caused by cerebral edema result in increased intracranial pressure (ICP). Signs and symptoms of increased ICP include headache, loss of sense of smell, and altered level of consciousness. Even a mild increase in ICP is sufficient to cause death of neural tissue caused by inadequate perfusion. Moderate and severe increases in ICP can cause brain tissue to shift position or herniate from one chamber into another and may also cause compression of neural structures.…
The leading cause of long term disability in the United States is stroke, and one American dies from stroke about every four minutes. Stroke by definition is the sudden death of brain cells due to lack of oxygen. The main types of stoke are hemorrhagic, ischemic, and a transient ischemic attack. Hemorrhagic stroke is broken in to two types, and the most common is the intracerebral hemorrhage, when an artery in the brain bursts flooding the brain with blood. The second and less common subarachnoid hemorrhage, when bleeding occurs in the area between the brain and the thin tissue that covers it.…
Lastly, a stroke can also occur the blood flow to the brain is…
The brain tissues begin to swell, and swelling can compress the brain and blood vessels. Lack of blood flow and oxygen can eventually cause a stroke. Some patients may or may not experience loss of consciousness and…
Overview Stroke and hemorrhagic stroke A stroke is a brain attack. It is caused when blood flow to an area of brain is cut off. Brain cells are deprived of oxygen and begin to die. After that, abilities for the brain cells in that area to memory and muscle control are lost.…
The movie that we viewed in class was My Beautiful Broken Brain. This film was mainly about Lotje Sodderland, and how she had experienced an intracerebral brain hemorrhage or a stroke. The film allows us to see what it was like along the road of recovery with her and all the struggles she underwent. A stroke, also known as cerebrovascular accident, is one of the most frequent cause of brain damage (Gilliam & Marquardt, 2016). There are multiple types of strokes (Gilliam & Marquardt, 2016).…
