We would like to think that dyspnea, like pain, serves as an early-warning sign of developing disease, respiratory or cardiac. To be effective as an early-warning. 2 presents the PA chest X-ray of the Blue Bloater patient on the left and the Pink Puffer patient on the right. Notice both the enlarged cardiac silhouette and. Abstract. Breathlessness, disability, and exercise tolerance were assessed in 26 patients with severe chronic airflow limitation (forced expiratory volume in one.

COPD clinical phenotypes

Early stages of COPD are often asymptotic, but may present as asthma, chronic bronchitis, emphysema or combinations. Both her mother and maternal grandfather were heavy smokers with rapidly progressive disease and premature death. Outpatient oxygen therapy in chronic obstructive pulmonary disease. Oxygen relieves bllue in “pink puffers”. Quite frequently, corti- costeroids are used for exacerbations and, in some cases, patients’ maintenance of corticosteroids, either by the oral or inhaled route is used.

Are “pink puffers” more breathless than “blue bloaters”?

No bronchodilator responsiveness is indicated. This is also increased, representing what has commonly been called ‘air-trapping’. Effect of systemic glucocorticoids on exacerbations of chronic obstructive pulmonary disease.

Support Center Support Center. Breathlessness, disability, and exercise tolerance were assessed in 26 patients with severe chronic airflow limitation forced expiratory volume in one second FEV1 less than or equal to 1 litre divided into two groups patients who were normocapnic pressure of arterial carbon dioxide Paco2 less than 5. A most interesting clinical variant of COPD presented following case scenario.


Obviously this is very precocious emphysema, marked by hyperinflation. The risk factors in this patient are smoking, family history, bule repeated chest infections during childhood.

At postmortem examination, heart weight was g, the tricuspid valve was pjnk cm, right ventricular thickness was 0. Following death and autopsy, pathological findings in relation to the loss of alveolar walls emphysemathe presence of mucous gland hyperplasia as expressed by the REID index, 17,18 and inflammation of small airways and right ventricular thickness are summarized in Table 3. The Lung Health Study revealed a marked degree of oink airways hyperreactivity in an inhaled methacholine challenge.

Asthma, Asthmatic bronchitis, Chronic bronchitis. Long-term oxygen therapy is the only treatment known to prolong life in blue bloaters, and oxygen concentrators and transtracheal oxygen delivery are discussed. When blood oxygen levels are low, your body naturally shunts blood from non-vital organs fingertips and lips to vital organs lungs, heart, and brain.

It must be emphasized that the distinction between asthmatic bronchitis, COPD, and chronic irreversible asthma is not clear-cut. Plain chest radiography cannot reliably diagnose emphysema in life, but a bloaater method measuring lung density from the computed tomographic CT scan allows location, quantitation, and diagnosis of emphysema defined by enlargement of distal air spaces in humans in life. Let us know at contact COPD. The patient was initially referred to the author for smoking cessation advice and management.

The fact that they are increased is highly significant. One patient was a year-old man, who was visiting from Germany. In addition, he was extremely dyspneic with a respiratory rate of In acute exacerbations with purulent sputum, antimicrobials against Streptococcus pneumoniae and Hemophilus influenzae are used with controlled oxygen therapy aiming to keep the arterial PO2 over 50 mm Hg without the pH falling below 7.


Purfer stages of disease are not characterized by any recog- nizable symptoms, puffet or X-ray abnormalities. What to make of this? A rapid decline in exercise capacity followed a bout of influenza at age Am J Respit Crit bule Med ; Thus, a Blue Bloaher might be considered to have a ‘lazy’ respiratory center and the Pink Puffer, one of high responsiveness or high ‘gain’ in the respiratory center.

The significance of morphologic chronic hyperplastie bronchitis. The patient persisted in trying to stop smoking, but could never get below ten cigarettes per day. Obstructive lung disease and low lung function in adults in the United States: The Lung health Study Research Group.

She had moderate nicotine withdrawal symptoms of irrita- bility, poor concentration, and some emotional lab- ility with frequent crying. This designation is consistent with the initial improvement of FEVi after nine months of the regular use of albu- terol for her symptoms of dyspnea, cough and wheeze. Although loss of elastic recoil and dis- appearance of alveolar walls are parallel processes, they are not necessarily related.

The patient’s pulmonary function evaluations on this visit are summarized on Table 6. Clin Sci Lond Jan; 60 1: This used to be called a barrel chest. Two- six- and minute walking tests in respiratory disease.

This assures that tissues are adequately oxygenated.
