Merriam-Webster defines hypothermia as a condition in which the temperature of the body is very low. This condition is a medical emergency that occurs when the body loses more heat than what it is able to produce; hence, the body temperature decreases. The part of the brain called the hypothalamus is responsible for controlling body temperature; therefore, hypothermia is the result of the dysfunction of the hypothalamus. In order for a person to become hypothermic, their body temperature must be…

Hypovolemia is a state in which the blood volume, specifically the volume of the blood plasma, is decreased. This can also lead to an imbalance in the volume contraction, or a decrease in the volume of body fluid, which includes osmolytes. Hypervolemia is often linked with sodium depletion, and is distinctly different from dehydration. Causes include loss of blood, loss of plasma, and loss of osmolytes via diarrhea and vomiting. It is recognized by tachycardia and diminished blood pressure, as…

mesenteric ischemia and injuries to the arteries; it can locate the exact bleeding site by showing the leakage of contrast into lumen if the patient is active bleeding…

Post-Biopsy Care and Complications: After the procedure is done, the skin nick is cleaned and dressed, and a repeat scan is obtained to rule out the presence of a pneumothorax. Most institutions obtain two post-biopsy chest radiographs, one immediate baseline and a repeat 2-3-hour study, to ensure no enlarging pneumothorax. The patients are observed until the follow up radiograph is obtained while fasting in case a chest tube insertion is needed (Fig. 5). The patient is discharged if the follow…

Moyamoya disease is a progressive, occlusive disease affecting the cerebral vasculature and the arteries that feed it. Moyamoya is a Japanese term meaning “puff of smoke.” When you view the appearance of the disease on an angiogram the abnormal vascular collateral networks developing adjacent to the stenotic vessels. This disease causes the carotid artery in the skull becomes blocked or narrowed. This will cause the blood flow to your brain to become greatly reduced. Tiny blood vessels…

Gangrene is a severe and possibly life-threatening condition that arises when blood supply to a certain part of the body is interrupted for an extended time. When blood cannot move freely through the body, cells die and infection can develop. When this occurs, the result is localized death of soft tissue (necrosis). Interruption in blood supply may result from an injury or infection, or in people suffering from any long-lasting health problem affecting blood flow. Any condition that affects…

Atherosclerosis is a cardiovascular disease whereby the arteries harden as a result of fatty deposits also known as plaque.Ather\o prefix meaning yellowish, fatty plaque and -sclerosis suffix meaning hardening. (Tsutsumi, n.d.).One of the main contributing factors towards this disease is high levels of cholesterol. The fatty deposit, plaque, grows steadily including both fibrous connective tissues. As the plaque accumulates, the walls of the arteries thicken and stiffen, and the obstruction of…

prevention program no matter what type of dog. The parasite is commonly called “heartworm”. It gets its name from the location where it is found most often; the heart. Nevertheless, it has been known to be in the pulmonary arterial system (lung arteries) and can have further damaging affects to lung vessels and…

1. What does the PR interval on the ECG represent? What is the normal value? The P-R interval is the interval between the beginning of electrical excitation of the atria and the beginning of excitation of the ventricles and its normal value is 0.12- 0.20 seconds. 2. What does the QRS complex on the ECG represent? What is implicit in the information that the QRS complexes on Mr. Ortega’s ECG had a normal configuration? The QRS complex is the most important in the EKG since its represents…

Tuberculosis is a very serious infection which affects the lungs and other parts of the body such as kidneys and bones joints. The lungs are the cone-shaped spongy like organs that are located in the chest cavity and make up most of the lower respiratory tract. Their most important function is to assist oxygen from the air that we breathe to enter the red blood cells in the blood. These red blood cells then carry the oxygen around the body to be used by other cells that are found in the entire…
