بررسی همبستگی و میزان توافق نتایج PaCO2 گازهای خون شریانی با CO2 انتهای بازدمی (End-Tidal CO2) توسط کاپنوگرافی در بیماران مبتلا به تشدید حاد بیماری انسدادی ریوی (COPD)

  Background : Chronic Obstructive Pulmonary Disease (COPD) represents a major public health problem. The course of COPD is characterized by episodic periods of worsening symptoms, termed exacerbations. Supplemental oxygen should be given to patients with COPD exacerbation without causing CO2 retention. Arterial blood gas sampling is the gold standard for monitoring adequate oxygenation and for...

Noninvasive measurement of mean alveolar carbon dioxide tension and Bohr's dead space during tidal breathing.

The lack of methodology for measuring the alveolar carbon dioxide tension (PA,CO2) has forced investigators to make several assumptions, such as that PA,CO2 is equal to end-tidal (PET,CO2) and arterial CO2 tension (Pa,CO2). The present study measured the mean PA,CO2 and Bohr's dead space ratio (Bohr's dead space/tidal volume (VD,Bohr/VT)) during tidal breathing. The method used is a new, simple...

Functional outcome of patients with chronic obstructive pulmonary disease and exercise hypercapnia.

Chronic hypercapnia is associated with a poor prognosis in chronic obstructive pulmonary disease (COPD). Some patients are normocapnic at rest but retain CO2 during exercise. The significance of this abnormality on the course of the disease is unknown. Sixteen stable COPD patients (13 males and 3 females, aged 60 +/- 5 yrs, mean +/- SD) who had previously undergone pulmonary function tests and ...

Ventilatory and cerebrovascular responses in normocapnic and hypercapnic COPD patients.

This study investigated the hypothesis that hypercapnia in some chronic obstructive pulmonary disease (COPD) patients may be related to a high cerebrovascular response to carbon dioxide (CO2). The relationship between responses of ventilation and of cerebral blood volume (CBV) to acute changes in carbon dioxide tension in arterial blood (Pa,CO2) was measured in 17 chronic hypercapnic (Pa,CO2 >6...

Mouth occlusion pressure, CO2 response and hypercapnia in severe chronic obstructive pulmonary disease.

The resting mouth occlusion pressure 0.1 s after onset of inspiration (P0.1) and minute ventilation (V'E) and their response to CO2 in patients with chronic obstructive pulmonary disease (COPD) remain controversial. The ventilatory drive and the factors that predict resting arterial CO2 tension (Pa,CO2) were studied in 19 eucapnic and 14 hypercapnic severe COPD patients, and 20 controls. The CO...
