COPD Case Flashcards
Paroxysmal nocturnal dyspnea (PND)
Sudden, severe shortness of breath at night that awakens a person from sleep, often with coughing and wheezing.
Paroxysmal nocturnal dyspnea (PND) is most closely associated with…
congestive heart failure
………commonly occurs several hours after a person with heart failure has fallen asleep. PND is often relieved by sitting upright, but not as quickly as simple orthopnea. Also unlike orthopnea, it does not develop immediately upon lying down.
Paroxysmal nocturnal dyspnea (PND)
Dyspnea which occurs when lying flat, forcing the person to have to sleep propped up in bed or sitting in a chair. It is commonly measured according to the number of pillows needed to prop the patient up to enable breathing (Example: “three pillow orthopnea”).
Orthopnea
Productive cough lasting 1-3 weeks
Acute Bronchitis
Productive cough for at least three months for the past two years
Chronic Bronchitis
gold standard for diagnosing COPD
Pulmonary function testing (PFT)
also best screening tool
It makes sense to get a chest x-ray when a patient presents with shortness of breath, not to rule in or out COPD, but to look for other diagnoses.

COPD encompasses ….
chronic bronchitis and emphysema
Which clinical diagnosis should be considered in any middle-aged or older adult who has:
dyspnea
chronic cough or sputum production, or
a history of tobacco use
COPD
Often related to rhinitis, allergy, or eczema
Asthma
play a role in what appears to be an allergic bronchoconstrictive response in asthma
Mast cells, T helper cells, and eosinophils
play a role in an inflammatory and destructive process in COPD
Macrophages, T killer cells, and neutrophils
Therapy for Mild Symptomatic COPD
Prescribe an albuterol metered-dose inhaler on an as needed basis.
(essential for symptom management in COPD)
All symptomatic patients with COPD should be prescribed a short-acting bronchodilator (e.g., albuterol) on an as-needed basis. If symptoms are still inadequately controlled, a daily dose of long-acting bronchodilator should be added. The choice between beta-2-agonist, anticholinergic, theophylline, or combination therapy depends on availability and individual response in terms of symptom relief and side effects. (See below.) Combining bronchodilators of different pharmacological classes may improve efficacy and decrease the risk of side effects compared to increasing the dose of a single bronchodilator.
when a patient younger than 45 years old is diagnosed with COPD…what should you consider?
alpha-1 antitrypsin deficiency
Since significant reversibility is defined as an increase in FEV1 of….
≥ 12%
as in the case of asthma…not COPD
Therapy for Moderate COPD
maintenance therapy of inhaled anticholinergics (ipratroprium or tiotroprium) alone or in combination with short-acting beta agonists may be utilized.
Therapy for Severe COPD
it is recommended that inhaled glucocorticosteroids be added to bronchodilator treatment.
The combination of an inhaled glucocorticosteroid combined with a long-acting ß2-agonist is more effective than each individual component, without increased side effects.
Recommended Immunizations for Patients with COPD
Influenza and pneumococcal vaccines are recommended for adults with COPD. If the patient is due for a tetanus booster, then he should receive TdaP
in a setting of COPD exacerbation, an individual may find…
Difficulty catching his or her breath Chest tightness Fever Increased coughing or A change in the cough (more productive, more mucus expelled)
An exacerbation of COPD is defined as an event in the natural course of the disease characterized by a change in the patient’s baseline dyspnea, cough, and/or sputum that is beyond normal day-to-day variations and is acute in onset. An exacerbation may warrant a change in regular medication in a patient with underlying COPD.
most common causes of COPD exacerbation
infection of the tracheobronchial tree and air pollution, but the cause of about a third of severe exacerbations cannot be identified.
effective treatments for exacerbations of COPD.
Inhaled bronchodilators (particularly inhaled beta 2-agonists with or without anticholinergics) and oral glucocorticosteroids are effective treatments for exacerbations of COPD.
Antibiotics should be given in COPD exacerbation when:
Patients with exacerbations of COPD with the following three cardinal symptoms: increased dyspnea, increased sputum volume, and increased sputum purulence, change in sputum color
one of the major complications of COPD
Heart Failure.
Chronic hypoxia (1) causes pulmonary vasoconstriction (2), which increases blood pressure in the pulmonary vessels. This elevation in blood pressure causes permanent damage to the vessel walls and leads to irreversible hypertension (3). The right heart eventually fails (4) because the pump cannot sustain flow effectively against this pressure. Right heart failure leads to an increase in preload, with peripheral edema and increased jugular venous distention.
The evidence isn’t 100% clear, but how often should a patient with COPD get PFTs?
at least annually for a patient who has COPD.
