Pulmonary capillary hemangiomatosis (PCH) is a disease affecting the blood vessels of the lungs, where abnormal capillary proliferation and venous fibrous intimal thickening result in progressive increase in vascular resistance. [1] It is a rare cause of pulmonary hypertension, and occurs predominantly in young adults.
Exercise-induced pulmonary hemorrhage (EIPH), also known as "bleeding" or a "bleeding attack", is the presence of blood in the airways of the lung in association with exercise. EIPH is common in horses undertaking intense exercise, but it has also been reported in human athletes, racing camels and racing greyhounds .
The gas could also enter the interstitial spaces within the lungs, the neck and larynx, and the mediastinal space around the heart, causing interstititial or mediastinal emphysema, or it could enter the blood vessels of the venous pulmonary circulation via damaged alveolar capillaries, and from there reach the left side of the heart, from which ...
Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term disease caused by a blockage in the blood vessels that deliver blood from the heart to the lungs (the pulmonary arterial tree). These blockages cause increased resistance to flow in the pulmonary arterial tree which in turn leads to rise in pressure in these arteries ...
Instead, the left heart fails to pump blood efficiently, leading to pooling of blood in the lungs and back pressure within the pulmonary system. This causes pulmonary edema and pleural effusions. [34] In the absence of pulmonary blood vessel narrowing, the increased back pressure is described as 'isolated post-capillary pulmonary hypertension ...
Symptoms may begin quickly or slowly depending on the size of the embolus and how much it blocks the blood flow. [2] Symptoms of embolisation in an organ vary with the organ involved but commonly include: Pain in the involved body part [2] Temporarily [2] decreased organ function; Later symptoms are closely related to infarction of the affected ...
Symptoms of a PE may include shortness of breath, chest pain particularly upon breathing in, and coughing up blood. [1] Symptoms of a blood clot in the leg may also be present, such as a red, warm, swollen, and painful leg. [1] Signs of a PE include low blood oxygen levels, rapid breathing, rapid heart rate, and sometimes a mild fever. [11]
Gas embolism is a diving disorder experienced by underwater divers who breathe gases at ambient pressure, and can happen in two distinct ways: . Pulmonary barotrauma: Air bubbles can enter the bloodstream as a result of gross trauma to the lining of the lung following a rapid ascent while holding the breath; the air held within the lung expands to the point where the tissues tear (pulmonary ...
