Obstructive Lung Disease: COPD, Asthma, and Related Diseases
| Question | Answer |
|---|---|
| acute exacerbation of COPD | state of worsening, often defined by the need to increase medication or to escalate care |
| airway hyperresponsiveness (AHR) | state of airways that cause them to constrict abnormally in response to stress or insults |
| airway inflammation | acute inflammation of the lungs contracted form the environment |
| airway obstruction | state of abnormally slowed expiration, characterized most commonly by a decrease in FEV1 |
| asthma | respiratory disorder characterized by recurring episodes of paroxysmal dyspnea, wheezing on expiration/inspiration caused by constriction of bronchi, coughing, and viscous mucoid bronchial secretions |
| bronchiectasis | abnormal condition of bronchial tree characterized by irreversible dilation and destruction of bronchial walls |
| bronchocilator | substance, especially a drug that relaxes contraction of the smooth muscle of bronchioles to improve ventilation to lungs |
| bronchospasm | abnormal contraction of smooth muscle of bronchi, resulting in acute narrowing and obstruction |
| chronic bronchitis | acute or chronic inflammation of mucous membranes of tracheobronchial tree |
| cystic fibrosis | autosomal recessive disease characterized by pancreatic insufficiency, abnormally thick secretions from exocrine glands, and increased concentration of sodium and chloride in sweat glands |
| emphysema | destructive process of lung parenchyma leading to permanent enlargement of distal air spaces, classified as either centrilobular or panlobular |
| noninvasive ventilation | mechanical ventilation performed without intubation or tracheostomy, usually with mask ventilation |
| supplemental oxygen | oxygen delivered at concentration exceeding 21% to increase amount circulating into blood |
