Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. [ 3 ][ 14 ] Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. [ 15 ] The severity of the condition is variable. [ 15 ]
Alveolar lung diseases are classified as processes that affect these units that ultimately lead to issues with ventilation. There are a number of different causes of insult to the alveoli including build up of fluid, hemorrhage, infection, malignancy and build up of protein and mineral deposits. Conditions classified under alveolar lung disease ...
A pulmonary alveolus (pl.: alveoli, from Latin alveolus, "little cavity"), also known as an air sac or air space, is one of millions of hollow, distensible cup-shaped cavities in the lungs where pulmonary gas exchange takes place. [1] Oxygen is exchanged for carbon dioxide at the blood–air barrier between the alveolar air and the pulmonary ...
A pulmonary consolidation is a region of normally compressible lung tissue that has filled with liquid instead of air. [1] The condition is marked by induration [2] (swelling or hardening of normally soft tissue) of a normally aerated lung. It is considered a radiologic sign. Consolidation occurs through accumulation of inflammatory cellular ...
Pneumonia is the most common, and frequent lower respiratory tract infection. This can be either viral, bacterial, or fungal. This can be either viral, bacterial, or fungal. This infection is very common because pneumonia can be airborne, and when you inhale this infection in the air, the particles enter the lungs and move into the air sacs.
Ventilation–perfusion coupling is the relationship between ventilation and perfusion, represented by the ventilation-perfusion ratio (V/Q). Ventilation rate (V) is the total gas volume that enters and leaves the alveoli in a given amount of time, commonly measured per minute. To calculate the ventilation rate, the tidal volume (inhaled or ...
Pulmonology. Lobar pneumonia is a form of pneumonia characterized by inflammatory exudate within the intra-alveolar space resulting in consolidation that affects a large and continuous area of the lobe of a lung. [1][2] It is one of three anatomic classifications of pneumonia (the other being bronchopneumonia and atypical pneumonia).
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.
