Studies on cardiac lymph during extracorporeal circulation.
Cardiac lymph in dogs was used to study the metabolism and state of the myocardium during extracorporeal circulation and various additional procedures. Changes in the flow characteristics, cdor and pH of lymph were noted, and corresponding samples of cardiac lymph and coronary sinus blood were analyzed for lactate concenlmtion. Ventricular fibrillation led to higher lactate levek when compared ...
متن کاملStudies on blood viscosity during extracorporeal circulation.
Blood viscosity was studied during extracorporeal circulation by means of a cone in cone viscometer. This rotational viscometer provides sixteen kinds of shear rate, ranging from 0.05 to 250.2 sec-1 • Merits and demerits of the equipment were described comparing with the capillary viscometer. In experimental study it was well demonstrated that the whole blood viscosity showed the shear rate dep...
متن کاملMyocardial protective effect of hypothermia during extracorporeal circulation -- by quantitative measurement of myocardial oxygen consumption -.
OBJECTIVE To evaluate the effect of systemic temperature on myocardial protection during extracorporeal circulation, we quantitatively evaluated the relationship between myocardial oxygen consumption and rectal temperature. MATERIALS AND METHODS Myocardial oxygen consumption during cardiac arrest was calculated via blood gas analysis of venous blood samples collected from the coronary sinus. ...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Fish oil reduces heart rate and oxygen consumption during exercise.
Dietary omega-3 polyunsaturated fatty acids (PUFAs) are readily incorporated into heart and skeletal muscle membranes where, in the heart, animal studies show they reduce O2 consumption. To test the hypothesis that omega-3 PUFAs alter O2 efficiency in humans, the effects of fish oil (FO) supplementation on O2 consumption during exercise were evaluated. Sixteen well-trained men (cyclists), rando...
