Cardiac Output by the Dilution Method without Arterial Sampling
The selection of an external site for a radioisotope determination of cardiac output is discussed with respect to satisfying the analytical conditions of the Stewart-Hamilton dilution equation. Examples of both single-chamber and multichamber recording are illustrated, along with a discussion of the difficulties of curve calibration and extrapola. tion from multiple sites. The development of a ...

متن کاملMeasurement of Cardiac Output using Bioimpedance Method
Cardiac output (CO), in conjunction with hemoglobin concentration and arterial oxygen saturation are the cornerstones of oxygen transport. Cardiac output is the functional expression of cardiovascular performance and can be used to confirm the need for, or usefulness of treatment. Determination of cardiac output is an important procedure in interventional cardiology and also used in cardiothora...
متن کاملUse of krypton85 for the measurement of cardiac output by the single-injection indicator-dilution technique.
W HEN radioactive krypton (Kr 85), a beta-emitting radioisotope, is introduced into the circulation, it does not act as a simple intravaseular indicator. As this substance, in solution in the blood stream, traverses the systemic capillary bed, it diffuses freely into the interstitial and intra-cellular spaces. When blood containing Kr 85 passes through the pulmonary capillary bed, approximately...
