Jan 31, 2024 · Acute respiratory distress syndrome (ARDS) is a life-threatening condition characterized by poor oxygenation and non-compliant or "stiff" lungs. The disorder is associated with capillary endothelial injury and diffuse alveolar damage. Once ARDS develops, patients usually have varying degrees of pulmonary artery vasoconstriction and may develop ...
Introduction. Respiratory failure is a clinical condition that happens when the respiratory system fails to maintain its main function, which is gas exchange, in which PaO2 is lower than 60 mmHg and/or PaCO2 higher than 50 mmHg. Respiratory failure is classified according to blood gases abnormalities into type 1 and type 2.

Feb 27, 2023 · Introduction. Acute respiratory failure occurs when the lungs do not release sufficient oxygen in the bloodstream, thus preventing the organs from functioning optimally. Acute respiratory failure also occurs due to insufficiency of the lungs to remove carbon dioxide from the blood, as a result of which carbon dioxide content increases in the ...
Abstract. Acute bronchiolitis is the most common lower respiratory tract infection (LRTI) during the first year of life. Respiratory syncytial virus (RSV) infection is the most prevalent virus found in these children, accounting for 60–80 % of cases. The rate of hospitalization is less than 2 %. Up to 8 % of those hospitalized require ...
Reviewed/Revised Apr 2024. Acute respiratory failure is a life-threatening impairment of oxygenation, carbon dioxide elimination, or both. The respiratory system oxygenates and eliminates carbon dioxide from venous blood. Thus, a useful classification of respiratory failure is whether the principal abnormality is. Many disorders affect both.
Respiratory failure occurs due mainly either to lung failure resulting in hypoxaemia or pump failure resulting in alveolar hypoventilation and hypercapnia. Hypercapnic respiratory failure may be the result of mechanical defects, central nervous system depression, imbalance of energy demands and supplies and/or adaptation of central controllers. Hypercapnic respiratory failure may occur either ...
