Airflow limitation that is not fully reversible is evident if post-bronchodilator FEV1/FVC is less than 0.70 and FEV1 is less than 80% predicted. o USPSTF recommends spirometry only in symptomatic patients- no direct evidence to support screening asymptomatic individuals. Sxs for considering a diagnosis and performing spirometry include dyspnea, cough, chronic sputum production, recurrent lower respiratory tract infections, hx of risk factors, fam hx of COPD, and/or childhood factors. o Although the GOLD guidelines are focused on spirometry results, FEV1 dec with age so the age-related change needs to be factored into interpretation of spirometry results. Spirometry has good sensitivity, although a peak expiratory flow measurement alone is unreliable when used as the only diagnostic tool because of weak specificity - In addition to results of spirometry, assessing the impact of COPD, the burden of disease, the risk of disease progression, and COPD exacerbation risk are integral components. o 13 disease-specific instruments have been identified as COPD assessment tools: assessment tools recommended for clinical practice include the COPD Assessment Test (CAT) and the COPD Control Questionnaire (The CCQ). Of the two, the CAT is widely utilized, applicable worldwide, and useful to predict clinical correlation of disease-related impact. - CXR: alone is not diagnostic of COPD but can provide value in excluding differential dxs, detecting the presence of concomitant pulmonary disease (bronchiectasis, pleural diseases, pulmonary fibrosis), pneumonia, or cardiac diseases (e.g., cardiomegaly). Chest radiography in early COPD appears normal. Abnormalities associated with COPD may be present on a chest x-ray, such as lung hyperinflation, hyperlucency of the lungs, or tapering of vascular markings. Structural lung disease may be seen on chest imaging (e.g., emphysema, gas trapping, or airway wall thickening) consistent with COPD. A chest x-ray in those having advanced COPD with emphysema may reveal hyperinflation, bullae or blebs, and a flat hemidiaphragm. A CXR is not recommended for screening of lung cancer. - Pulse oximetry: is a noninvasive intervention to assess a patient’s arterial oxygen saturation and need for supplementation oxygen therapy.

Pulmonary rehabilitation has been shown to be a highly effective therapeutic intervention to improve dyspnea, health status, and exercise intolerance - Long-term supplemental O2 therapy in patients with severe resting hypoxemic COPD has been shown to improve survival. Additional benefits include reductions in nocturnal hypoxemia and arrhythmias, reduction in polycythemia, dyspnea, inc exercise tolerance, and improved cognitive status. Criteria for oxygen therapy include PaO2 = 55 mm Hg or SaO2 = 88% with or without hypercapnia confirmed twice over a 3-week period; or PaO2 = 55 to 60 mm Hg or NR 601 Midterm Exam Study Guide latest LATEST UPDATE GRADED/RATED A+ NR 601 Midterm Exam Study Guide latest LATEST UPDATE GRADED/RATED A+ SaO2 = 88% if there is evidence of pulmonary hypertension, polycythemia, or peripheral edema suggesting HF - Anxiety/depression are comorbidities associated w COPD, poor health outcomes. Assess for sxs and provide psych interventions. Pharmacological management is the cornerstone of COPD treatment and is directed at sx reduction, reducing the risk and severity of COPD exacerbations, and improving exercise tolerance and health status. - Surgical options: When dyspnea is unrelieved by medications and interferes w quality of life, consider eval for surgical options. Lung volume reduction therapy, lung resections, transplants, and laser bullectomy are available in selected circumstances. - Clinician–patient communication should include a discussion of disease progression and patient choices for care Pharmacological Treatment - Individualized. A step-wise approach to therapy is utilized in tx of COPD. No current drug therapy has been proved to influence the long-term, progressive decline in lung function. - Classes of medications o Inhaled Beta2-Agonist Bronchodilators: Bronchodilators to reverse bronchoconstriction by relaxing smooth muscles in the airways. Acute bronchospasms lead to permanent airway remodeling. There are two types of beta2-agonists: SABAs and LABAs. SABAs, AKA ―rescue‖ inhalers, for intermittent sxs on an as-needed basis. Meds: albuterol or levalbuterol. Onset is rapid, about 15 to 30 minutes, and duration of action is 4 to 6 hours. Beta-agonists are sympathomimetic agents with adverse effects that may include transient tachycardia, nervousness, palpitations, and/or arrhythmia. o LABAs: used for maintenance therapy to prevent acute bronchospasms and not for relief of acute symptoms. The duration is about 12 hours. Ex: Formoterol and salmeterol o Inhaled Anticholinergic/Antimuscarinic Bronchodilators: block the bronchoconstriction effects of acetylcholine on muscarinic cholinergic receptors in the smooth muscle of the airways. The short-acting antimuscarinic (SAMA) agent, ipratroprium, has a duration of 6-8 hrs, used in long-term and acute COPD management. Tiotropium, a long-acting anticholinergic/antimuscarinic, is used for maintenance of COPD. Duration of action is about 24 hrs. Tiotropium demonstrated more benefits, such as fewer COPD exacerbations, reduced hospital admissions, and improved quality of life, as compared to ipratropium. *Antimuscarinic agents have anticholinergic properties and should be used cautiously in patients with narrow-angle glaucoma, prostatic hypertrophy, or bladder neck obstruction, and are contraindicated in patients who are allergic to atropine o Combo Bronchodilator Therapy: When used in combo, bronchodilators w/ diff MOAs may improve degree of bronchodilation w/ a lower risk of increasing a monotherapy agent. - Stable COPD Pts w/ sxs: Combination inhaled therapy w/ LABAs, ICSs, or long-acting inhaled anticholinergics, may be more effective than the agents as individuals. - Stable, moderate to very severe COPD: a maintenance combo of an ICS/LABA or ICS and inhaled long-acting anticholinergic therapy are recommendations.

Restrictive pattern o Restrictive lung disease typically has normal or increased FEV1/FVC o Decreased TLC, FEV1, and FVC with a normal FEV1/FVC, and a low DLCO o Typically, these are patients with interstitial lung disease, severe skeletal abnormalities, or diaphragmatic paralysis o The flow volume loop is generally normal in appearance, but has low lung volumes Spirometry (Kahn Academy video and readings) Know definitions for each spirometry criteria o Spirometry measures two key factors: o Expiratory forced vital capacity (FVC) o Forced expiratory volume in one second (FEV1). o Your doctor also looks at these as a combined number known as the FEV1/FVC ratio. o If you have obstructed airways, the amount of air you’re able to quickly blow out of your lungs will be reduced.
