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.
Emphysema is any air-filled enlargement in the body's tissues. [ 5 ] Most commonly emphysema refers to the permanent enlargement of air spaces (alveoli) in the lungs, [ 5 ][ 6 ] and is also known as pulmonary emphysema. Emphysema is a lower respiratory tract disease, [ 7 ] characterised by enlarged air-filled spaces in the lungs, that can vary ...
Proposed. [edit] Purinergic signalling is an important regulatory mechanism in a wide range of inflammatory diseases. It is understood that shifting the balance between purinergic P1 and P2 signalling is an emerging therapeutic concept that aims to dampen pathologic inflammation and promote healing. [ 13 ]
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
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.
Intensive care medicine, pulmonology, internal medicine. Respiratory acidosis is a state in which decreased ventilation (hypoventilation) increases the concentration of carbon dioxide in the blood and decreases the blood's pH (a condition generally called acidosis). Carbon dioxide is produced continuously as the body's cells respire, and this ...
Pulmonary hypertension (PH or PHTN) is a condition of increased blood pressure in the arteries of the lungs. [ 7 ] Symptoms include shortness of breath, fainting, tiredness, chest pain, swelling of the legs, and a fast heartbeat. [ 7 ][ 1 ] The condition may make it difficult to exercise. [ 7 ] Onset is typically gradual. [ 8 ]
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system.The flow of blood is critically important to body tissues particularly in the delivery of oxygen as is vital to sustain metabolic proceses.The flow of blood or cardiac output is a difficult thing to measure.
