A pulmonary contusion is a bruise of the lung tissue caused by trauma. Damaged capillaries can cause blood and other fluids to accumulate in the tissue of the lung, impairing gas exchange . Pulmonary edema is the buildup of fluid in the parenchyma and alveoli usually caused by left ventricular heart failure, or by damage to the lung or its ...

Pulmonary edema, also known as pulmonary congestion, is excessive liquid accumulation in the tissue and air spaces (usually alveoli) of the lungs. It leads to impaired gas exchange and may cause hypoxemia and respiratory failure.It is due to either failure of the left ventricle of the heart to remove oxygenated blood adequately from the pulmonary circulation (cardiogenic …

Hypoxic pulmonary vasoconstriction (HPV), also known as the Euler-Liljestrand mechanism, is a physiological phenomenon in which small pulmonary arteries constrict in the presence of alveolar hypoxia (low oxygen levels). By redirecting blood flow from poorly-ventilated lung regions to well-ventilated lung regions, HPV is thought to be the primary mechanism underlying …

Because of the large compliance of pulmonary circulation, it provides an indirect measure of the left atrial pressure.. For example, it is considered the gold standard for determining the cause of acute pulmonary edema; this is likely to be present at a PWP of >20mmHg.It has also been used to diagnose severity of left ventricular failure and mitral stenosis, given that elevated …

Edema, also spelled oedema, and also known as fluid retention, dropsy, hydropsy and swelling, is the build-up of fluid in the body's tissue. Most commonly, the legs or arms are affected. Symptoms may include skin which feels tight, the area may feel heavy, and joint stiffness. Other symptoms depend on the underlying cause.

Uma radiografia postero-anterior do tórax é a tradicionalmente feita; outras vistas (lateral ou lordótico) ou imagens de tomografia computadorizada podem ser necessárias.. Em tuberculose pulmonar ativa, infiltrações ou consolidações e/ou cavidades são frequentemente vistas na parte superior dos pulmões com ou sem linfadenopatia (doença nos nódulos linfáticos) mediastinal …

Pulmonary hemorrhage (or pulmonary haemorrhage) is an acute bleeding from the lung, from the upper respiratory tract and the trachea, and the pulmonary alveoli.When evident clinically, the condition is usually massive. The onset of pulmonary hemorrhage is characterized by a cough productive of blood and worsening of oxygenation leading to cyanosis. ...

Altitude sickness, the mildest form being acute mountain sickness (AMS), is the harmful effect of high altitude, caused by rapid exposure to low amounts of oxygen at high elevation. People can respond to high altitude in different ways. Symptoms may include headaches, vomiting, tiredness, confusion, trouble sleeping, and dizziness. Acute mountain sickness can progress to high …

Ephedrine is a medication and stimulant. It is often used to prevent low blood pressure during anesthesia. It has also been used for asthma, narcolepsy, and obesity but is not the preferred treatment. It is of unclear benefit in nasal congestion. It can be taken by mouth or by injection into a muscle, vein, or just under the skin. Onset with intravenous use is fast, while injection into a ...

肺水腫（はいすいしゅ、pulmonary edema）とは、肺の実質（気管支、肺胞）に水分が染みだして溜まった状態をいう。 溜まった水分により呼吸が障害され、呼吸不全に陥る。. 概要. 肺は酸素を取り入れ、二酸化炭素を排出するために、肺胞に空気を取り入れる 。 肺胞は網目状の毛細血 …
