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 ...
Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic.
An early morning sample is preferred. [7] E-nose showed the ability to smell the cause of the exacerbation. [8] The definition of a COPD exacerbation is commonly described as "lost in translation", [9] meaning that there is no universally accepted standard with regard to defining an acute exacerbation of COPD. Many organizations consider it a ...
In context of acute hypoxemia, oxygen therapy should be titrated to a target level based on pulse oximetry (94–96% in most patients, or 88–92% in people with COPD). [ 12 ] [ 8 ] This can be performed by increasing oxygen delivery, described as F I O 2 (fraction of inspired oxygen).
Asthma is a respiratory disease that can begin or worsen due to exposure at work and is characterized by episodic narrowing of respiratory airways. Occupational asthma has a variety of causes, including sensitization to a specific substance, causing an allergic response; or a reaction to an irritant that is inhaled in the workplace.
Murrell began treating patients with small doses of glyceryl trinitrate in 1878, and the substance was widely adopted after he published his results in The Lancet in 1879. [7] The medical establishment used the name "glyceryl trinitrate" or "trinitrin" to avoid alarming patients, because of a general awareness that nitroglycerin was explosive.
