Lewis - Ch 29 - Obstructive Pulmonary Diseases: Nursing Management

What is Obstructive Pulmonary Disease?
The most common chronic lung disease, includes diseased characterized by increased resistance to airflow as a result of airway obstruction or airway narrowing.
What are the types of Obstructive Pulmonary Disease?
Asthma, COPD, cystic fibrosis, and bronchiectasis.
What is Asthma?
Is a chronic inflammatory lung disease that results in variable episodes of airflow obstruction, but is usually reversible.
What does chronic inflammation in Asthma lead too?
Recurrent episodes of wheezing, breathlessness, chest tightness, cough, particularly at night or in the early morning.
What are the risk factors of Asthma?
Related to the patient (e.g., genetic factors), or the environment. Obesity as well, and gender.
What are the gender differences for males with Asthma?
Male gender is a risk factor for asthma in children, but not adults for unclear reasons. Before puberty males are more affected.
What are the gender differences for females with Asthma?
After puberty and into adulthood, women are more affected then men. Women who are admitted to the ER are more likely to need hospitalization. Death rates in women are greater then men.
What are the cultural and ethnic health disparities in regards to Asthma with African Americans?
Higher prevelance rates over 38%, females have the highest mortality rate.
What are the cultural and ethnic health disparities in regards to Obstructive Pulmonary Diseases with Whites?
Highest incidence of COPD, highest incidence of Cystic Fibrosis.
What are the cultural and ethnic health disparities in regards to Obstructive Pulmonary Diseases with Puerto Ricans?
Higher asthma prevalence rates and age adjusted death rates than all other racial and ethnic subgroups.
What is the Genetic Risk factor with Asthma?
Asthma has a component that is inherited. Numerous genes are involved. Atopy the genetic predisposition to develop an allergic (IgE-mediated) response to common allergies, is a major risk factor.
What is the Immune Response Risk factor with Asthma?
Hygiene response hypothesis is thought to play a role in Asthma.
How do Allergies effect Asthma?
Indoor and outdoor allergens are well known to trigger asthma. House dust mites, cockroaches, furry animals, fungi and mold can trigger.
How does exercise effect Asthma?
Induced or exacerbated asthma. Occurs after vigorous exercise. Symptoms are pronounced during activities where there is exposure to cool, dry air.
How do air pollutants effect Asthma?
Cigarette or wood smoke, vehicle exhaust, elevated ozone levels, sulfur dioxide, and nitrogen dioxide can trigger an attack.
How does cigarette smoking effect Asthma?
Associated with an accelerated decline of lung function. Increases the severity of the disease, may cause patients to be less responsive to treatment with corticosteroids (systemic or inhaled), and reduces the chance of asthma being controlled.
What are occupational factors with Asthma?
Job-related exposures. Irritants cause a change in the responsiveness of the airways. Agricultural workers, painters, plastics manufacturing, and cleaning work are high risk. Arrive at work feeling well but experience gradual development of symptoms towards the end of the day.
How do Respiratory Infections effect Asthma?
Major precipitating factors in acute asthma attacks. RSV and rhinovirus are two factors in developing and increasing severity of Asthma. Cause an increase in hyperresponsiveness of the bronchial system.
How do nose and sinus problems effect Asthma?
Allergic rhinitis is a major predictor. Treatment of allergic rhinitis may reduce frequency of exacerbation. Chronic sinus problems can cause inflammation of the mucus membranes.
What is the Asthma Triad?

What happens when some asthmatics take aspirin or NSAIDS?
Wheezing will develop within two hours. Usually rhinorrhea, congestion, and tearing occurs. Facial flushing, GI symptoms, and angioedema can occur.
How can B-Adrenergic Blockers PO or topical eyedrops effect Asthma?
May trigger asthma because of bronchospasms.

Used as preservatives and sanitizing agents. Commonly found in fruits, beer, and wine used extensively in salad to prevent oxidation. Can cause asthma exacerbation.
How does GERD effect Asthma?
Postulated that reflux of stomach acid into the esophagus can be aspirated into the lungs, causing relfex vagal stimulation and bronchoconstriction.
What are the Psychological Factors with Asthma?
Emotional stress, extreme emotions such as crying, laughing, anger and fear can lead to hyperventilation and hypocapnia, which can cause airway narrowing.
What is the Pathophysiology of Asthma?
Persistent but variable inflammation of the airway. Airflow is limited because of inflammation results in bronchoconstriction, airway hyperresponsiveness, and edema of the airways.
What are the inflammatory cells that are involved with Asthma?
Mast cells, macrophages, eosinophils, neutrophils, T and B lymphocytes, and epithelial cells of the airways.
How long does it take for someone to have an early phase response with Asthma?
30 - 60 minutes after exposure to allergen or irritant.
How long does it take for someone to have an late phase response with Asthma?
4 - 10 hours after initial attack because of eosinophil and lymphocyte activation and their release of more inflammatory mediators. Epithelial cells also produce cytokines and other inflammatory mediators.. Can persist for 24 hours or more.
What is the allergic asthma response?
Triggered when an allergen cross links IgE receptors on Mast cells, which are activated to release histamine and other inflammatory mediators (early-phase response). A late phase response may occur due to further inflammation.
What are the clinical manifestations of Asthma?
Wheezing, cough, dyspnea, chest tightness after exposure to a precipitating factor or trigger. Expiration may be prolonged. Expiratory ration may be prolonged to 1:3, or 1:4. Bronchospasm, edema, and mucus in the brochioles, narrowing.

Hypoxemia, restlessness, increased anxiety, inappropriate behavior, increased pulse and blood pressure, and pulsus paradoxus (a drop in systolic during during the inspiratory cycle greater than 10 mm Hg). Difficulty speaking, increased RR (^30), use of accessory muscles. Hyperresonance on percussion, auscultating with wheezing. Silent chest indicates severe obstruction and impending respiratory failure.
How can Asthma be classified?
Intermittent, mild persistent, moderate persistent, or severe persistent.

What is collaborative therapy for Asthma?
ID and avoidance/elimination triggers, patient and caregiver teaching, drug therapy, asthma action plan, desensitization, assess for control.
What does a severe of life-threatening asthma exacerbation indicate?
SaO2, ABGs, inhaled B2-adrenergic agonists, inhaled anticholinergic agents, )2 by mask or nasal prongs, IV or oral corticosteroids, IV fluids, IV magnesium or/and heliox, intubation or assisted ventilation.
What do ABG's reveal with a person with Asthma?

Corticosteroids (systemic) (e.g., prednisone) - considered quick-relief when used in a short burst 3-10 days at the start of therapy or during a period of gradual deterioration.
How do Corticosteroids effect Asthma?
Antiinflammatory medications that reduce bronchial hyperresponsiveness, block the late-phase reaction, and inhibit migration of inflammatory cells. More effective in improving asthma control then any other long term drug.
How do Leukotriene Modifiers effect Asthma?
Leukotriene receptor blockers (antagonists) and leukotriene synthesis inhibitors interfere with the synthesis or block the action of leukotrienes - inflammatory mediators produced from arachidionic acid metabolism.
