Determination of Blood Volume in the Heart and Lungs
نویسندگان
چکیده
The dilution curve of the specific activity of the erythrocytes in the arterial blood after intravenous injection of labeled erythrocytes with p32 has been treated mathematically. It is possible with the help of the dilution curve to calculate the minute volume of the heart and the thoracic pool (the residual blood of the heart + the blood content of the lungs). The values of the thoracic pool amount to about 30 per cent of the total circulatory blood-volume.

Several therapeutic methods require an artificial lung (oxygenator) to replace the physiological function of lung. For instance, in some acute respiratory syndromes, the patient’s lungs are unable to perform their normal function and would need an assistive device to fulfill their performance. Moreover, in cardio-pulmonary bypass, when the heart has stopped pumping, blood is not sent to the lun...

Background: The dose-related effects of patient setup errors on bio-physical indices were evaluated for the conventional wedge (CW) and field-in-field (FIF) whole breast irradiation techniques (WBI). Materials and Methods: The treatment plans of 10 patients receiving left WBI were retrospectively selected for evaluation. The bio-physical effects of dose variations were evaluated by shifting the...
