Cardiac output (co, also denoted by the symbols and ˙), is a term used in cardiac physiology that describes the volume of blood being pumped by the heart, in particular by the left or right ventricle, per unit timecardiac output is the product of the heart rate (hr), or the number of heart beats per minute (bpm), and the stroke volume (sv), which is the volume of blood pumped from the. To estimate the dose, a patient’s body weight or body surface area (bsa) is often used1 bsa is difficult to measure directly, but may be calculated using formulae involving the patient’s weight and height1, 2 here we discuss bsa and when it is used in practice, in particular, for calculating drug doses in children and for cancer chemotherapy.

Abstract the dose of most cancer chemotherapeutic drugs administered to dogs is calculated on the basis of estimated body surface area (bsa) however, results of some chemotherapy trials have revealed that this dosing method increases toxicosis in small dogs. The body surface area (bsa) is the measured surface of a human body as it is less affected by abnormal adipose mass, bsa is found to be a better indicator of metabolic mass it can be calculated using various formulas. Body surface area calculation the formula for caculating the patient's body surface area (bsa) used in the corrected creatinine clearance calculation requires that the patient's height in inches and weight in pounds be supplied.

How to calculate the stroke volume index you can also use this stroke volume calculator to find the stroke volume index, normalized with respect to the body surface area (bsa) this way, you can easily compare your result with someone who has a different body type. An interest in the calculation of the body surface area (bsa) should be dosed on the basis of the bsa because it reflects the volume of extracellular fluid and the total volume of body water more precisely than the body weight itself 25 body surface area and body weight predict total liver volume in western adults.
