This can be particularly beneficial in conditions involving lung inflammation, as it helps to alleviate the inflammatory response and promote healing of the lung tissue. [13] Improvement of Lung Compliance and Oxygenation. The removal of excess material from the alveoli improves lung compliance (the ability of the lungs to expand and contract).
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]
Crackles are caused by the "popping open" of small airways and alveoli collapsed by fluid, exudate, or lack of aeration during expiration. Crackles can be heard in people who have pneumonia , atelectasis , pulmonary fibrosis , acute bronchitis , bronchiectasis , acute respiratory distress syndrome (ARDS), interstitial lung disease or post ...
Doctors explain the safest and most effective way to blow your nose. Here, experts share how to remove mucus quickly and safely.
Alveoli are the spherical outcroppings of the respiratory bronchioles. Pulmonary surfactant is a surface-active complex of phospholipids and proteins formed by type II alveolar cells . [ 1 ] The proteins and lipids that make up the surfactant have both hydrophilic and hydrophobic regions.
Atelectasis is the partial collapse or closure of a lung resulting in reduced or absence in gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
Diffuse alveolar damage (DAD) is a histologic term used to describe specific changes that occur to the structure of the lungs during injury or disease.Most often DAD is described in association with the early stages of acute respiratory distress syndrome (). [1]
Within the medical field of respiratory therapy, Open lung ventilation is a strategy that is utilized by several modes of mechanical ventilation to combine low tidal volume and applied PEEP to maximize recruitment of alveoli.
