Factors that can increase the D LCO include polycythaemia, asthma (can also have normal D LCO) and increased pulmonary blood volume as occurs in exercise.Other factors are left to right intracardiac shunting, mild left heart failure (increased blood volume) and alveolar hemorrhage (increased blood available for which CO does not have to cross a barrier to enter).
D LCO measurement has been standardized according to a position paper [1] by a task force of the European Respiratory and American Thoracic Societies. In respiratory physiology , the diffusing capacity has a long history of great utility, representing conductance of gas across the alveolar-capillary membrane and also takes into account factors ...
Lung compliance, or pulmonary compliance, is a measure of the lung's ability to stretch and expand (distensibility of elastic tissue). In clinical practice it is separated into two different measurements, static compliance and dynamic compliance.
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...

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 ...
Testosterone levels increase in adolescence after puberty and into early adulthood, and naturally decline over time, usually starting in a man’s 40s or fifties. However, this drop now seems to ...
The Social Security 2024 COLA increase was a disappointment for many retirees. As of now, the Social Security COLA projection for 2025 is a drop compared to the 2024 COLA, which could feel like a ...
