A. LESSON PREVIEW/REVIEW
Introduction:
Hello, PHINMA Ed student! Welcome to Nursing Care of Clients with Life Threatening Conditions/Acutely Ill/Multi-Organ
Problems/High Acuity and Emergency Situations (Acute and Chronic) – Lecture. This professional subject of BS Nursing
deals with concepts, principles and techniques of nursing care of at-risk and sick adult clients with life-threatening
conditions, acutely ill/multi-organ problems, high acuity and emergency situation toward health promotion, disease
prevention, restoration and maintenance and rehabilitation.
In today’s session, you are tasked to set expectations as you get oriented with what the subjects is all about and to
determine the nature of your mode of learning. You may write in this area the vital policies, rules, and regulations to be
noted in this class. You may also refer to the Course Outline to be provided by your instructor.
B. MAIN LESSON
Classification
There are two classifications of COPD: chronic bronchitis and emphysema. These two types of COPD can be sometimes
confusing because there are patients who have overlapping signs and symptoms of these two distinct disease processes
Pathophysiology
In COPD, the airflow limitation is both progressive and associated with an abnormal inflammatory response of the
lungs to noxious gases or particles
An inflammatory response occurs throughout the proximal and peripheral airways, lung parenchyma, and
pulmonary vasculature.
Due to the chronic inflammation, changes and narrowing occur in the airways.
There is an increase in the number of goblet cells and enlarged submucosal glands leading to hypersecretion of
mucus.
Scar formation. This can cause scar formation in the long term and narrowing of the airway lumen.
Wall destruction. Alveolar wall destruction leads to loss of alveolar attachments and a decrease in elastic recoil.
The chronic inflammatory process affects the pulmonary vasculature and causes thickening of the vessel lining
and hypertrophy of smooth muscle.
Causes of COPD includes environmental factors and host factors. These includes
Smoking depresses the activity of scavenger cells and affects the respiratory tract’s ciliary cleansing mechanism.
Occupational exposure. Prolonged and intense exposure to occupational dust and chemicals, indoor air
pollution, and outdoor air pollution all contribute to the development of COPD.
Genetic abnormalities. The well-documented genetic risk factor is a deficiency of alpha1- antitrypsin, an enzyme
inhibitor that protects the lung parenchyma from injury.
Clinical Manifestations: The natural history of COPD is variable but is a generally progressive disease.
Chronic cough. Chronic cough is one of the primary symptoms of COPD.
Sputum production. There is a hyperstimulation of the goblet cells and the mucus-secreting gland leading to
overproduction of sputum.
Dyspnea on exertion. Dyspnea is usually progressive, persistent, and worsens with exercise.
Dyspnea at rest. As COPD progress, dyspnea at rest may occur.
Weight loss. Dyspnea interferes with eating and the work of breathing is energy depleting.
Barrel chest. In patients with emphysema, barrel chest thorax configuration results from a more fixed position
of the ribs in the inspiratory position and from loss of elasticity.
Prevention of COPD is never impossible. Discipline and consistency are the keys to achieving freedom from chronic
pulmonary diseases.
Smoking cessation. This is the single most cost-effective intervention to reduce the risk of developing COPD
and to stop its progression.
Healthcare providers should promote cessation by explaining the risks of smoking and personalizing the “at-risk”
message to the patient.
Chest x-ray: May reveal hyperinflation of lungs, flattened diaphragm, increased retrosternal air space, decreased
vascular markings/bullae (emphysema), increased bronchovascular markings (bronchitis), normal findings during
periods of remission (asthma).
Pulmonary function tests: Done to determine cause of dyspnea, whether functional abnormality is obstructive or
restrictive, to estimate degree of dysfunction and to evaluate effects of therapy, e.g., bronchodilators. Exercise
pulmonary function studies may also be done to evaluate activity tolerance in those with known pulmonary
impairment/progression of disease.
Arterial blood gases (ABGs): Determines degree and severity of disease process, e.g., most often Pao 2is
decreased, and Paco2 is normal or increased in chronic bronchitis and emphysema, but is often decreased
in asthma; pH normal or acidotic, mild respiratory alkalosis secondary to hyperventilation
(moderate emphysema or asthma).
DL CO test: Assesses diffusion in lungs. Carbon monoxide is used to measure gas diffusion across the
alveocapillary membrane. Because carbon monoxide combines with hemoglobin 200 times more easily than
oxygen, it easily affects the alveoli and small airways where gas exchange occurs. Emphysema is the only
obstructive disease that causes diffusion dysfunction.
Bronchogram: Can show cylindrical dilation of bronchi on inspiration; bronchial collapse on forced expiration
(emphysema); enlarged mucous ducts (bronchitis).
Lung scan: Perfusion/ventilation studies may be done to differentiate between the various pulmonary
diseases. COPD is characterized by a mismatch of perfusion and ventilation (i.e., areas of abnormal ventilation in
area of perfusion defect).
Complete blood count (CBC) and differential: Increased hemoglobin (advanced emphysema), increased
eosinophils (asthma).
Blood chemistry: alpha1-antitrypsin is measured to verify deficiency and diagnosis of primary emphysema.
Sputum culture: Determines presence of infection, identifies pathogen.
Cytologic examination: Rules out underlying malignancy or allergic disorder.
Electrocardiogram (ECG): Right axis deviation, peaked P waves (severe asthma); atrial dysrhythmias
(bronchitis), tall, peaked P waves in leads II, III, AVF (bronchitis, emphysema); vertical QRS axis (emphysema).
Exercise ECG, stress test: Helps in assessing degree of pulmonary dysfunction, evaluating effectiveness of
bronchodilator therapy, planning/evaluating exercise program.
Management of Exacerbations
Optimization of bronchodilator medications is first-line therapy and involves identifying the best medications or
combinations of medications taken on a regular schedule for a specific patient.
Hospitalization. Indications for hospitalization for acute exacerbation of COPD include severe dyspnea that does
not respond to initial therapy, confusion or lethargy, respiratory muscle fatigue, paradoxical chest wall movement,
and peripheral edema.
Oxygen therapy. Upon arrival of the patient in the emergency room, supplemental oxygen therapy is
administered and rapid assessment is performed to determine if the exacerbation is life-threatening.
Antibiotics. Antibiotics have been shown to be of some benefit to patients with increased dyspnea, increased
sputum production, and increased sputum purulence.
Surgical Management
Patients with COPD also have options for surgery to improve their condition.
Bullectomy. Bullectomy is a surgical option for select patients with bullous emphysema and can help reduce
dyspnea and improve lung function.
Lung Volume Reduction Surgery. Lung volume reduction surgery is a palliative surgery in patients with
homogenous disease or disease that is focused in one area and not widespread throughout the lungs.
Lung Transplantation. Lung transplantation is a viable option for definitive surgical treatment of end-stage
emphysema
