A measurement of arterial blood gas in the exacerbation of 54 patients with the chronic obstructive pulmonary disease shown that the arterial PaO2 was reduced in 20 patients (37%) and arterial PaCO2 was increased in 30 patients (55.6%). Among patients with the reduction of arterial PaO2¬, 14 patients experienced the respiratory failure, mainly type II respiratory failure. During the exacerbation of the disease, the arterial PaO2 reduction can occur in all 3 stages of the COPD.

Background: Exacerbation of chronic obstructive pulmonary disease (COPD) is the common complication of COPD and sometimes is lethal cause of patients. Objective: To study clinical manifestations of exacerbation of 150 patients with COPD by Anthonisen's classification at the Department of Respiratory of Bach Mai hospital. Subjects and method: A retrospective, prospective, descriptive study included 150 patients in Department of Respiratory of Bach Mai hospital, from February 2005 to March 2006. Retrospective study included 100 patients and prospective study included 50 patients. Results and conclusions: The male - to - female ratio is 6:1. The average age of patients was 68.85 \xb1 9.45 years. The most of age group was 61 - 70 years. 73.33% patients hospitalized were belonged to type I - this was serious type and similarity of III-IV stage according to GOLD 2003' classification of COPD. 100% of cases hospitalized with dyspnea, 90.6% cough with purulent sputum, 58.7% fever.

The article introduced two approaches for diagnosis of chronic obstructed pulmonary disease (COPD): definitive diagnosis by pulmometry with bronchial dilation maneuver and staging diagnosis. 4 current treatments include: reducing risk factors, drug treatment in stable periods (treatment regimen, bronchodilators, glucocorticoid and other medication), non-drug treatment (rehabilitation, long-term oxygen therapy, surgical treatment) and treatment for exacerbation.

A study on 30 patients with COPD with average ages of 68,3+/-11,59 and 30 healthy people with the same age has shown that the arterial blood gas helped to classify the respiratory failure, especially in the acute crisis of COPD, indicate the oxygen therapy for improving the condition of oxygen deficiency but did not help to predict the pulmonary arterial pressure. There was a difference of volume equity dilatation time and AT between disease group and control. There was relatively to closely correlation between RVP, PAPm, PAPs.

Age of onset (Asthma: all age range, COPD over 46 years old) sexes (Asthma female > male, COPD 3/4 male). Clinical forms: Asthma (3/4 mild and moderated persistent, infective Asthma 12.1%, variant cough asthma 4.4%), COPD (Bronchitic and emphysematous forms 71.5%, post pulmonary tuberculosis sequels 8.8%, with 63% severe and very severe stage in which 10.9% acute exacerbations. Ventilation tests showed that the ventilatory norm was decreased both in asthma and COPD, while more decline in COPD. Asthma test was a useful test for differential diagnosis between COPD and asthma, Positive tests in COPD was 8% and negative tests in asthma was 15%.

Chronic obstructive pulmonary disease (COPD) is a substantially under-diagnosed disorder, and the diagnosis is usually delayed until the disease is advanced. However, the benefit of early diagnosis is not yet clear, and there are no guidelines in Korea for doing early diagnosis. This review highlights several issues regarding early diagnosis of COPD. On the basis of several lines of evidence, early diagnosis seems quite necessary and beneficial to patients. Early diagnosis can be approached by several methods, but it should be confirmed by quality-controlled spirometry. Compared with its potential benefit, the adverse effects of spirometry or pharmacotherapy appear relatively small. Although it is difficult to evaluate the benefit of early diagnosis by well-designed trials, several lines of evidence suggest that we should try to diagnose and manage patients with COPD at early stages of the disease.

We propose a clinical pathway of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) based on state machine. Clinical event-driven response was utilized to control workflow execution of the AECOPD clinical pathway. By comparison with the traditional clinical pathway management, clinical numerical results showed that the proposed method was better in hospitalization days, average hospitalization expense and aberration rate, and better handled the variability in the AECOPD clinical pathway execution.

“Saber-sheath” trachea is a deformity of lower cervical or intrathoracic trachea. The configuration of the deformity is marked coronal narrowing associated with sagittal widening. This deformity is associated with chronic obstructive pulmonary disease. We report a case of patient with saber-sheath who underwent total laryngectomy. Although the patient had no tracheal collapse after the total laryngectomy, crusted discharge was increased. Diagnosis of the saber-sheath trachea, possible causes, and clinical implications are discussed.
