Invalidity of hand heating as a method to arterialize venous blood.
We have assessed in normal subjects the validity of using hand heating to obtain "arterialized" venous blood by biochemical comparison of results for "arterialized" venous and true arterial (radial artery) blood samples. The heating regimen involved placing one hand in an air-heated box at 45-50 degrees C for 45 min. This method produced blood that was "arterialized" for lactate, PCO2, HbO2, an...
متن کاملCorrelation of simultaneously obtained capillary, venous, and arterial blood gases of patients in a paediatric intensive care unit.
AIMS To investigate the correlation of pH, partial pressure of oxygen (PO2), partial pressure of carbon dioxide (PCO2), base excess (BE), and bicarbonate (HCO3) between arterial (ABG), venous (VBG), and capillary (CBG) blood gases. METHODS Patients admitted to the paediatric intensive care unit (PICU) in Cukurova University between August 2000 and February 2002 were enrolled. RESULTS A tota...
متن کاملParadoxical evolution of arterial blood gases during exercise in patients with chronic obstructive bronchitis.
In more than a thousand chronic obstructive lung disease (COLD) patients we have observed in six cases, that exercise-induced hypercapnia was accompanied by a concomitant improvement in arterial oxygen tension (PaO2) and a decrease in the alveolo-arterial O2. This behaviour was not due to technical errors. We explained the increase in PaO2 during exercise by three nonmutually exclusive mechanis...
متن کاملDistribution of blood flow within the skin of the rabbit with particular reference to hair growth.
• Isotopic clearance techniques using radioactive inert gases have permitted assessment of the capillary blood flow in a number of organs. In certain organs, such as heart and testis, the clearance curve is a monotonic exponential function suggesting uniform distribution of the capillary blood flow. However, in other organs such as the kidney, the clearance curve can be analyzed into a number o...
متن کاملEffects of syringe material, sample storage time, and temperature on blood gases and oxygen saturation in arterialized human blood samples.
BACKGROUND The practice of on-ice storage of arterial-blood samples in plastic syringes for delayed analysis continues, and the effects of storage time and temperature on the measurement of blood-oxygen-saturation values (S(aO2)) have not been adequately described. OBJECTIVE To determine the effects of syringe material, storage time, and storage temperature on normal arterialized blood gas an...
