Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate, abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing.
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.
Any references on the internet to pneumonoultramicroscopicsilicovolcanoconiosis or silicosis being caused by 'sharp particles [which] lacerate lining of lungs; causing victim to leak air from their lungs while simultaneously bleeding into their lung cavity' [13] are inaccurate. Particles of a size able to enter the lung (< 10 μm ...
lung injury of acute onset, within 1 week of an apparent clinical insult and with the progression of respiratory symptoms; bilateral opacities on chest imaging (chest radiograph or CT) not explained by other lung pathology (e.g. effusion, lobar/lung collapse, or nodules) respiratory failure not explained by heart failure or volume overload ...
The peel can become deeper than 2 cm. [2] Within the chest, the lung is compressed and unable to expand (trapped lung), making it vulnerable to collapse and causing breathlessness. [7] Restrictive lung disease from fibrothorax may occur when pleural fibrosis is so severe that it involves the diaphragm and ribcage and results primarily from ...
Restrictive lung diseases are a category of extrapulmonary, pleural, or parenchymal respiratory diseases that restrict lung expansion, [2] resulting in a decreased lung volume, an increased work of breathing, and inadequate ventilation and/or oxygenation. Pulmonary function test demonstrates a decrease in the forced vital capacity.
Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction ...
Centrilobular emphysema is the most common type usually associated with smoking, and with chronic bronchitis. [17] The disease progresses from the centrilobular portion, leaving the lung parenchyma in the surrounding (perilobular) region preserved. [23] Usually the upper lobes of the lungs are affected. [17]
