Clinical laboratory tests showed microcytic anemia (hemoglobin 10g/dl), plasma sodium 111mEq/l (normal value [NV]: 135–155mEq/l), plasma osmolarity 229mOsm/l (NV: 280–300), PCR 64mg/l (NV: 0–5), normal creatinine levels, urinary sodium 76mEq/l (NV: 54 [archbronconeumol.org]
Also, older age, heart disease, anemia, resting tachycardia, hypercapnia, and hypoxemia decrease survival, whereas a significant response to bronchodilators predicts improved survival. [msdmanuals.com]
Treatment, depending on severity of symptoms, typically starts with anticoagulants; the presence of ominous signs (low blood pressure) may warrant the use of thrombolytic drugs.[2] Anemia[edit] Anemia that develops gradually usually presents with exertional [en.wikipedia.org]

Respiratoric
- Cough
The cilia help move mucus up the tubes so it can be coughed out. In chronic bronchitis, the tubes have lost their cilia. This makes it hard to cough up mucus, which causes more coughing. More coughing makes the tubes more irritated. [copdfoundation.org]
BACKGROUND: Cough and sputum production (symptoms of bronchitis) are common in chronic obstructive pulmonary disease (COPD). [ncbi.nlm.nih.gov]
Chronic bronchitis It is defined clinically as persistent productive cough for at least 3 months in 2 (or more) consecutive years. [symptoma.com]
These include the following: Coughing every day over a period of months. Smokers often refer to this as "smoker's cough." [rush.edu]
- Dyspnea
MEASUREMENT OF DYSPNEA IN COPD Section: The two purposes of measuring dyspnea are: to differentiate between patients who have less dyspnea and those who have more dyspnea (discriminate), and to determine whether dyspnea has changed over time and/or as [dx.doi.org]
Thus, hyperinflation is directly associated with patient-centered outcomes such as dyspnea and exercise limitation. [ncbi.nlm.nih.gov]
With this continuous method the patient reports twice the number of dyspnea ratings during exercise compared with discrete ratings each minute. [oadoi.org]
- Sputum Production
Chronic cough and sputum production often precede the development of airflow limitation by many years, although not all individuals with cough and sputum production go on to develop COPD. [who.int]
The diagnosis of chronic obstructive pulmonary disease (COPD) should be suspected in patients with risk factors (primarily a history of smoking) who report dyspnea at rest or with exertion, chronic cough with or without sputum production, or a history [ncbi.nlm.nih.gov]
- Chronic Cough
This case report emphasizes that not all chronic cough and dyspnea are attributable to COPD. [ncbi.nlm.nih.gov]
The most common symptoms of COPD are breathlessness, or a 'need for air', excessive sputum production, and a chronic cough. [who.int]
- Productive Cough
Symptoms are productive cough and dyspnea that develop over years; common signs include decreased breath sounds, prolonged expiratory phase of respiration, and wheezing. [web.archive.org]
We report a 55-year-old male ex-smoker who presented with complaints of exertional breathlessness and productive cough for five years and an episode of haemoptysis four days prior to presentation. [ncbi.nlm.nih.gov]

Cardiovascular
- Heart Failure
Heart failure shares some general symptoms with COPD; thus, diagnosing COPD is difficult in subjects with a history of heart failure, and spi-rometry is mandatory for confirmation. [ncbi.nlm.nih.gov]
- Cyanosis
Cf Blue bloater. pink puffer A facetious term sometimes used by doctors to describe patients breathless from CHRONIC lung disease but still able to maintain sufficient oxygenation of the blood to avoid CYANOSIS. Compare BLUE BLOATER. [medical-dictionary.thefreedictionary.com]
The is caused by the lack of oxygen in the bloodstream, a condition known as cyanosis. Decreased oxygen can also lead to the swelling in the legs and ankle ( peripheral edema ). [verywell.com]
Other possible COPD symptoms include a lack of energy; unintentional weight loss in later stages; swelling in ankles, feet or legs; and cyanosis (lips or fingernails take on a bluish hue). COPD causes The causes of COPD are not fully understood. [copdnewstoday.com]
In addition to severe COPD symptoms, signs of end-stage COPD include: Blueness of the lips or fingernail beds (cyanosis) Chronic respiratory failure Treatment may require oxygen therapy or surgery. [everydayhealth.com]
- Chest Pain
PE should receive increased awareness in patients with unexplained AE-COPD, especially when pleuritic chest pain and signs of cardiac failure are present, and no clear infectious origin can be identified. [ncbi.nlm.nih.gov]
Symptoms Morning cough is often the earliest sign of the disease, followed by noisy breathing, chest pain, and breathlessness. People with COPD sometimes develop a barrel-shaped chest due to an enlargement of the lungs. [sleepfoundation.org]
Symptoms and signs may include: Fatigue Dyspnea Paroxysmal nocturnal dyspnea (PND) Chest tightness Wheezing Cough with sputum (mucoid and/or purulent) Fever Chest pain Workup consists of a detailed history, tests and physical examination. [symptoma.com]
Other symptoms Less common symptoms of COPD include: weight loss tiredness swollen ankles from a build-up of fluid (oedema) chest pain and coughing up blood – although these are usually signs of another condition, such as a chest infection or possibly [nhs.uk]
Conversely, a 20-year-old healthy man with sudden onset of severe, sharp chest pain and back pain may be suspected of having a dissecting thoracic aortic aneurysm because those clinical features are common in aortic dissection. [msdmanuals.com]
- Tachycardia
The severity of COPD correlates with various arrhythmic manifestations such as atrial fibrillation, atrial flutter, and either sustained or nonsustained ventricular tachycardia. [ncbi.nlm.nih.gov]
The lack of oxygen combined with the build-up of carbon dioxide can lead to a myriad of symptoms, including: Shortness of breath Wheezing Persistent cough Excessive mucus production Chronic fatigue Rapid heartbeat ( tachycardia ) More than four million [verywell.com]

Affected infants may present in the newborn period with cholestatic jaundice, sometimes with acholic stools (pale or clay-coloured) and hepatomegaly. [dx.doi.org]
Musculoskeletal
- Osteoporosis
Overtreatment with inhaled corticosteroids exposes these patients to an increased risk of potentially severe side-effects such as pneumonia, osteoporosis, and oropharyngeal candidiasis. Moreover, it represents a major waste of health-care spending. [ncbi.nlm.nih.gov]
If the air pocket bursts during a coughing fit, the lung will deflate heart problems – the heart has to work extremely hard to pump blood through the damaged lungs osteoporosis – where bones become thin and break more easily. [betterhealth.vic.gov.au]
Although primarily a lung disease, it is increasingly recognized that COPD has secondary associations, including muscle weakness and osteoporosis. [britannica.com]
Prevention of osteoporosis is important and starts with avoiding unnecessary treatment, particularly corticosteroids. [nps.org.au]
Neurologic
- Irritability
Whatever the exact cause may be, the common factor is airway irritation, which leads to inflammation and then damage. [symptoma.com]
Chronic bronchitis Chronic bronchitis is irritation and inflammation (swelling) of the lining in the bronchial tubes (air passages). The irritation causes coughing and an excess amount of mucus in the airways. [my.clevelandclinic.org]
Other irritants that may contribute to COPD include second-hand smoke, air pollution, and exposure to chemical fumes in the workplace. [medicare.com]
Long-term exposure to chemical fumes, vapors and dusts in the workplace can irritate and inflame your lungs. Exposure to fumes from burning fuel. [mayoclinic.org]

Findings of right ventricular hypertrophy include an R or R′ wave as tall as or taller than the S wave in lead V1; an R wave smaller than the S wave in lead V6; right-axis deviation >110° without right bundle branch block; or some combination of these [msdmanuals.com]
QRS Wave
- Poor R Wave Progression
ECG poor R wave progression requires an R wave in V3 <3 mm clockwise rotation of the heart secondary to hyperinflation results in a delayed precordial transition zone the lead in which the R/S ratio becomes >1, usually occurring in V3 or V4, shifts laterally [radiopaedia.org]
Serum
- Hypercapnia
Before mechanical ventilation, coma could be confirmed to be due to CO2 narcosis caused by exorbitant arterial hypercapnia (PCO2, 193 mm Hg). Pneumothorax was diagnosed in the hospital by chest x-ray and resolved after pleural drainage. [ncbi.nlm.nih.gov]
These findings indicate that, under the conditions investigated, arteriolar renal resistances are increased, perhaps because of local adrenergic discharge secondary to hypercapnia. [thorax.bmj.com]
Hypercapnia and Respiratory Acidosis A major complicance in COPD patients is the development of stable hypercapnia [6, 7]. [hindawi.com]
All patients requiring hospitalization for an acute exacerbation should undergo testing to quantify hypoxemia and hypercapnia. Hypercapnia may exist without hypoxemia. [msdmanuals.com]

Treatment
Oxygen
In a cluster randomised, controlled parallel group trial, in 405 patients, titrated oxygen significantly reduced mortality, hypercapnia and respiratory acidosis [8].
Medications
Medications that can be used include:
- Bronchodilators: These are given in pumps, to be inhaled as many times as prescribed.
- Corticosteroids: These are given to stop the inflammation from worsening. They can be used as inhalers (inhaled corticosteroids ICS) in mild to moderate disease, or given per oral in advanced disease.
- Leukotriene inhibitors: To stop action of leukotrienes in the inflammatory pathway
- Long-acting Beta 2 Agonists: Their use is associated with improved quality of life and reduced exacerbations, but they have not been shown to reduce mortality or serious adverse events significantly. [9].
- Antibiotics: For prophylactic treatment.
Cessation of smoking
Smoking should be immediately stopped to prevent the disease from worsening.
Removal of pollutants
Prolonged exposure to pollutants, such as smoke, asbestos, silica, etc should be avoided.
Prognosis
COPD is due to irreversible damage to the airways. This means this disease can be managed, not treated. Prognosis depends upon the stage of the disease and the treatment started. With appropriate treatment and cessation of smoking, COPD can be prevented from worsening and a relatively healthy life style can be adopted.
Complications
- Worsening of the condition/stage
- Lung scarring and fibrosis
- Pneumonia
- Right sided heart failure
- Weight loss
- Arrhythmias
- Pneumothorax
- Need for oxygen mask
Etiology
In most patients, COPD is the result of long-term heavy cigarette smoking; about 10% of patients are nonsmokers [3]. Other causes may include alpha-1 anti-trypsin deficiency, bronchiectasis and cystic fibrosis. Exposure to large amounts of air pollutants may also lead to development of COPD.
Whatever the exact cause may be, the common factor is airway irritation, which leads to inflammation and then damage. This results first in mucosal and glandular changes in the airways, and as the disease progresses, these changes are unable to match up with the continuously on going irritation, and irreversible damage occurs. The type of COPD depends upon the exact causative factor.
Epidemiology
Incidence
COPD is estimated to be the fourth leading cause of death in the United States and the sixth leading cause of death world wide.
Sex and Race
There is a clear cut association between heavy cigarette smoking and emphysema, and women and African-Americans are more susceptible than other groups [2]. However, generally men are much more commonly found to be suffering from COPD than women.
Age
COPD is more common in people, particularly men, aged 40 years and above.
Pathophysiology
COPD is a vast term that is used to describe three prominent disorders collectively. These include the following:
Emphysema
Emphysema is a condition of the lung characterised by irreversible enlargement of the air spaces distal to the terminal bronchiole, accompanied by destruction of their walls without obvious fibrosis [4].
It is defined clinically as persistent productive cough for at least 3 months in 2 (or more) consecutive years. The earliest feature of chronic bronchitis is hypersecretion of mucus in the large airways, associated with hypertrophy of the submucosal glands in the trachea and bronchi [5].
It is a chronic inflammatory disorder in which patients suffer from recurrent episodes of wheezing, breathlessness and cough. Many cells play a role in the inflammatory response, in particular lymphocytes, eosinophils, mast cells, macrophages, neutrophils and epithelial cells [6].
Chronic bronchiolitis, or small airway disease, also comes under the COPD category and shares many characteristics with the former two conditions. In a recent study, the overlap between these three disorders was found to be substantial [7].
Prevention
The use of continuous prophylactic antibiotics results in a clinically significant benefit in reducing exacerbations in COPD [10].
COPD can be easily prevented by not smoking tobacco and other such harmful agents. Also, avoiding exposure to pollutants can also prevent this disease from occurring.
Summary
Chronic obstructive pulmonary disease (COPD) is a common respiratory condition involving the airways and characterised by airflow limitation [1]. It is diagnosed based on clinical findings and results of pulmonary function tests. In acute COPD, symptoms are mild and the disease is often missed. As the disease progresses, varying symptoms present in different people.
