Capillary blood gases in COPD

Capillary blood gases: to arterialize or not.

Arterial versus capillary blood gases: a meta-analysis.

A meta-analysis determined whether capillary blood gases accurately reflect arterial blood samples. A mixed effects model was used on 29 relevant studies obtained from a PubMed/Medline search. From 664 and 222 paired samples obtained from the earlobe and fingertip, respectively, earlobe compared to fingertip sampling shows that the standard deviation of the difference is about 2.5x less (or the...

The Changes of Arterial Blood Gases in COPD During Four-year Period

INTRODUCTION COPD (Chronic Obstructive Pulmonary Disease) is characterized by airflow limitation that is not fully reversible and that can lead to respiratory failure. OBJECTIVE To show the changes of arterial blood gases in COPD during the 4-year evolution of illness. MATERIAL AND METHODS The research was done on patients suffering from COPD treated at the Clinic "Podhrastovi" during 2006 ...

Blood Reaction and Blood Gases in Pneumonia.

Peabody in 1912 (1) published a paper on the metabolism in pneumonia, in which he reviewed the previous literature and studied among other factors the blood gases and acid-base balance. Since Peabody, a number of other investigators have studied the blood gases and the question of the existence and importance of acidosis in pneumonia. The present paper is a report of observations on these subje...

Impaired training-induced adaptation of blood pressure in COPD patients: implication of the muscle capillary bed

BACKGROUND AND AIMS Targeting the early mechanisms in exercise-induced arterial hypertension (which precedes resting arterial hypertension in its natural history) may improve cardiovascular morbidity and mortality in COPD patients. Capillary rarefaction, an early event in COPD before vascular remodeling, is a potential mechanism of exercise-induced and resting arterial hypertension. Impaired tr...
