Overview of Obstructive Pulmonary Disorders Flashcards
What are the three classification of Obstructive Pulmonary disorders?
Obstruction from conditions in the wall of the lumen, related to loss of lung parenchyma, obstruction of airway lumen
What are the disorders from obstruction due to change in condition of the wall of the lumen?L
Asthma, acute bronchitis, Chronic bronchitis
What are the disorders from loss of lung parenchyma?
Emphysema
What are the conditions from obstruction of the airway?
Bronchiectasis, Bronchiolitis, Cystic Fibrosis, Acute tracheiobronchial obstruction, Epiglottitis, Croup
What is the decreasing order of Reversibility with Asthma, Chronic Bronchitis, and Emphysema?
Asthma, Chronic Bronchitis, Emphysema
What is the decreasing order of Sputum Production with asthma, chronic bronchitis, and emphysema?
Chronic bronchitis, asthma=emphysema
What is the decreasing order of alveolar damage with asthma, chronic bronchitis, and emphysema?
Emphysema, Chronic bronchitis, asthma
What is the condition with Increased airway responsiveness to stimuli that is partially or completely reversible?
asthma
Which type of asthma has a strong familial connection, shows a positive skin test to allergens, and allergen-specific immunotherapy is helpful, allergenic or non-allergenic?
Allergenic
What type of asthma is developed in middle age, is intrinsic, no family history, antigen-antibody reactions are less important, and allergen specific immunotherapy is NOT helpful, allergenic or non-allergenic?
Non allergenic
Which type of asthma has a less favorable prognosis, allergenic or non-allergenic?
non-allergenic
What is the pathophysiology of allergic asthma?
allergen stimulates, inflammatory mediators secrete cytokines that result in hypersecretion of mucus, epithelial shedding, sub epithelial fibrosis, plasma leakage, vasolilation, bronchoconstriction due to parasympathetic activation
Pathological Mechanisms of asthma?
Smooth muscle contraction/hyperplasia/hypertrophy, submucosal thickening, mucus, cellular debris in lumen
What are some things you could hear in a history of an asthma patient?
Dyspnea, occupational exposure to something
What would you find during a physical examination of an asthma patient?
Rapid breathing, tachycardia, pulsus paradoxus (decreased SV during inspiration), accessory muscles used, longer expiratory phase than inspiratory, hyperinflated chest, hyperresonance, WHEEZING
