The meaning of ASTHMA is a chronic lung disorder that is marked by recurring episodes of airway obstruction (as from bronchospasm) manifested by labored breathing accompanied especially by wheezing and coughing and by a sense of constriction in the chest
Patients presenting with overlapping clinical features of asthma and chronic obstructive pulmonary disease (COPD) may be described with the term asthma-COPD overlap (ACO). ACO has been recognised in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) and Global Initiative for Asthma (GI...
is indicated for the elimination of bronchial spasm in asthma, inflammation of the bronchi, in diseases of the respiratory system, in the pathological expansion of the bronchioles. The drug is prescribed for the relief of day and night spasm, in the presence of chronic abstructive lung disease....
On the other hand, aging per se causes changes in lung elastic recoil and pulmonary mechanics that causes FEV1/FVC to decrease; hence, older subjects may be more prone to fulfil the diagnostic criteria of ACOS regardless of the duration of their asthma.19 that all the patients investigated ...
In contrast to chronic obstructive pulmonary disease and chronic bronchitis, the inflammation of asthma is reversible. In contrast to emphysema, asthma affects the bronchi, not the alveoli. The National Heart, Lung and Blood Institute defines asthma as a common chronic disorder of the airways charact...
Pathophysiology of asthma: A: Lung and airway anatomy B: Cross-section of a normal airway C: In asthma, exaggerated airway constriction, inflammation, and increased mucus production lead to restriction of airflow. Image by Lecturio.Other mechanismNon-eosinophilic ...
OBSTRUCTIVE lung diseasesASTHMACHRONIC obstructive pulmonary diseasePRINCIPAL components analysisASTHMATICSSymptoms of asthma and COPD often overlap, and both diseases can co-exist in one patient. The asthma control questionnaire (ACQ) and clinical COPD questionnaire (CCQ) were developed to assess disease...
The pooled prevalence of asthma in patients with COVID-19 was similar to that in the general population, and asthma might be an independent protective factor for the death of patients with COVID-19, which suggests that we should pay high attention to patients co-infected asthma and COVID-19...
Exposure to air pollution poses a significant public health threat and, globally, is responsible for 7 million premature deaths every year [1] owing to illnesses such as asthma, chronic obstructive pulmonary disease (COPD) and lung cancer [2]. The health impacts of air pollution span the entire...
Lung function tests, such as spirometry and peak expiratory flow rates, measure how well your lungs are working. Allergy testingcan show if allergies to pollen, molds, dust mites, animal dander, or other items trigger your asthma. How is persistent asthma treated?
