Pulmonary edema (British English: oedema), also known as pulmonary congestion, is excessive fluid accumulation in the tissue or air spaces (usually alveoli) of the lungs. [1] This leads to impaired gas exchange, most often leading to shortness of breath (dyspnea) which can progress to hypoxemia and respiratory failure.
Emergency medicine, wilderness medicine. High-altitude pulmonary edema (HAPE) is a life-threatening form of non-cardiogenic pulmonary edema that occurs in otherwise healthy people at altitudes typically above 2,500 meters (8,200 ft). [2] However, cases have also been reported between 1,500–2,500 metres or 4,900–8,200 feet in more vulnerable ...
Symptoms that may indicate life-threatening altitude sickness include: Pulmonary edema (fluid in the lungs) Symptoms similar to bronchitis Persistent dry cough Fever Shortness of breath even when resting Cerebral edema (swelling of the brain) Headache that does not respond to analgesics Unsteady gait Gradual loss of consciousness Increased ...
A common response cascade to a variety of irritant gases includes inflammation, edema and epithelial sloughing, which if left untreated can result in scar formation and pulmonary and airway remodeling. Currently, mechanical ventilation remains the therapeutic mainstay for pulmonary dysfunction following acute inhalation injury.
Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. [ 1 ] Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). [ 1 ] For those who survive, a decreased quality of life is common.
Pulmonology. Swimming induced pulmonary edema (SIPE), also known as immersion pulmonary edema, is a life threatening condition that occurs when fluids from the blood leak abnormally from the small vessels of the lung (pulmonary capillaries) into the airspaces (alveoli). [2][3] SIPE usually occurs during exertion in conditions of water immersion ...
A pulmonary contusion, also known as lung contusion, is a bruise of the lung, caused by chest trauma. As a result of damage to capillaries, blood and other fluids accumulate in the lung tissue. The excess fluid interferes with gas exchange, potentially leading to inadequate oxygen levels (hypoxia). Unlike pulmonary laceration, another type of ...
Respiratory arrest is a serious medical condition caused by apnea or respiratory dysfunction severe enough that it will not sustain the body (such as agonal breathing). Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest.
