Pulmonary/Pain Flashcards
(189 cards)
Airway disorder that is worse on expiration (more force is needed to expel the air out of the lungs)
obstructive pulmonary disorders
examples of obstructive pulmonary disorders
asthma, chronic bronchitis, emphysema
Clinical Manifestations of \_\_\_\_\_\_\_: Dyspnea Wheezing Work of breathing Ventilation/perfusion mismatch Decreased forced expiratory volume (FEV1)
obstructive pulmonary disorders
most common cause for chronic bronchitis and emphysema; contributes to worsening asthma
Smoking
chronic Inflammatory disorder of airways characterized by bronchial hyperresponsiveness and constriction with intermittent periods of reversible airflow obstruction “attacks” (rarely some degree of obstruction that is always present)
asthma
Asthma is a _____ disorder
familial
multiple allergens and microbes may play a role in ________
asthma
theory of asthma cuase that states low exposure to microbes leads to increased development of asthma and atopic disorders; excessive cleanliness is thought to eliminate the microbial stimulation of the immune system that is needed to prevent atopic asthma
Hygiene Hypothesis
Risk Factors for \_\_\_\_\_\_: Family history Allergen exposure Urban living (cockroach/dirt) Air pollution Cigarette smoke Recurrent URIs – especially RSV Other atopic disorders
Asthma
50% of children with _________ will have reoccurring wheezing & eventually diagnosed with asthma within 6 years following the infection
RSV bronchitis
episodic attacks of bronchospasm, bronchial inflammation, mucosal edema, and increased mucus production
patho of asthma
_______ activates the APCs to present to the CD4 T cells in acute asthmatic response
antigen exposure
Clinical manifestations of \_\_\_\_\_\_\_\_\_: Expiratory wheezing Tightness Dyspnea Prolonged expiration Cough- Sometimes (especially in children), cough is the only sign Increased constriction (wheezing with both inhalation & exhalation) Tachycardia = hypoxemia May become status asthmaticus
Asthma
Diagnosis of ______:
FEV1 before & after a short acting bronchodilator is delivered before and after it is given via inhalation
• Will have improvement in expiratory flow volume after the inhaler is used
Asthma
Hypersecretion of mucous and chronic productive cough for at least 3 months of each year x 2 consecutive years
Chronic Bronchitis
Risk Factors for \_\_\_\_\_\_\_: smoking occupational dust chemicals pollution any factor that affects fetal/infant lung growth genetic susceptibility
Chronic Bronchitis
Airway inflammation with an infiltration of neutrophils, macrophages, and lymphocytes into the bronchial walls lead to bronchial edema, increased goblet cells (mucous cells), thick tenacious mucus, poor ciliary action r/t increased in mucus & increased susceptibility to infection, obstruction d/t mucus plugs
Patho of Chronic Bronchitis
Clinical Manifestation of \_\_\_\_\_\_\_\_\_: decreased exercise tolerance wheezing SOB copious productive cough (especially in the AM) polycythemia decreased FEV1
Chronic Bronchitis
abnormal permanent enlargement of gas exchange airways with destruction of alveolar walls without fibrosis; obstruction occurs d/t loss of alveolar elastic recoil that would push the air out of the alveoli
Emphysema
type of emphysema that is autosomal recessive and inherited deficiency of alpha-1 antitrypsin protein involving A1A inhibiting protolytic breakdown of the alveoli **Pts are usually younger than those with secondary emphysema and tested via cheek swab
Primary Emphysema
type of emphysema that is more prevalent and caused by cigarette smoking usually or air pollution /childhood URIs may contribute
Secondary Emphysema
cigarette smoke inhibits antiproteases & stimulates inflammation which increase the protease (enzymes) that attack alveolar walls and diminish elastic recoil which leads to alveoli growing in size and the septa is lost and air is trapped bc it can no longer be squeezed out
Patho of Emphysema
Type of Emphysema:
• Associated with smoking
• Occurs with chronic bronchitis (co-diagnosis)
• Destruction of bronchioles & alveolar ducts in upper lobes
• Alveolar sac remains intact
Centriacinar (centrilobular) Emphysema
Type of Emphysema that is located adjacent to the pleura and septal lines
Paraseptal Emphysema
