What is normal BSA level?
1.7 m2
The average adult BSA is 1.7 m2 (1.9 m2 for adult males and 1.6 m2 for adult females). This number is used to calculate dosages for cytotoxic anticancer agents.
What BSA is obese?
The DuBois and DuBois (Arch Intern Med 1916;17:863-71) BSA equation is the most widely used, although derived from only 9 subjects. … The overall BSA was 2.04 +/- 0.24 m(2): 1.81 +/- 0.19 m(2) in normal-weight, 1.99 +/- 0.16 m(2) in overweight, and 2.21 +/- 0.22 m(2) in obese subjects.
What is BSA in cardiology?
Cardiac index (CI) is a haemodynamic parameter that relates the cardiac output (CO) from left ventricle in one minute to body surface area (BSA), thus relating heart performance to the size of the individual.
What is BSA weight?
In physiology and medicine, the body surface area (BSA) is the measured or calculated surface area of a human body. For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass.
What is BSA vs BMI?
While Body Mass Index (BMI) is a measure of a person’s body fat mass, Body Surface Area measures the total surface area of a person’s body and is frequently used in order to calculate drug dosage and the amount of fluids to be administered by IV.
How do you calculate BSA for chemotherapy?
Cancer Chemother Rep 1970;54:225-35.
- Equation: BSA (m2) = 0.0235 x Height(cm)0.42246 x Weight(kg)0.51456
- Equation: BSA (m2) = 0.024265 x Height(cm)0.3964 x Weight(kg)0.5378
- Equation: BSA (m2) = SQR RT ( [Height(cm) x Weight(kg) ]/ 3600 )

Is a low heart index good?
If your heart doesn’t pump enough blood to supply your body and tissues, it could signal heart failure. Low output also could happen after you’ve lost too much blood, had a severe infection called sepsis, or had severe heart damage.
What is a good cardiac index?
The cardiac index is an assessment of the cardiac output value based on the patient’s size. To find the cardiac index, divide the cardiac output by the person’s body surface area (BSA). The normal range for CI is 2.5 to 4 L/min/m2.
How do I calculate BSA?
According to Mosteller’s “simplified calculation of body-surface area In metric terms” the body surface area = the square root of product of the weight in kg times the height in cm divided by 3600.
What is a BSA test?
Body Surface Area (BSA) measures the total surface area of a person’s body and is frequently used in order to calculate drug dosage. … It calculates BSA by taking the square root of height (cm) multiplied by weight (kg) divided by 3600.
How is carboplatin dosed?
-This drug is usually administered by an infusion lasting 15 minutes or longer. -No pre- or post-treatment hydration or forced diuresis is required. -The target AUC of 4 to 6 mg/mL/min using single agent carboplatin appears to provide the most appropriate dose range in previously treated patients.
Why is chemotherapy based on body surface area?
Dosing based on body surface area (BSA) is generally used in an effort to normalize drug concentrations. This is because it is well recognized that measures of many physiologic parameters that are responsible for drug disposition, including renal function and energy expenditure, can be normalized by use of BSA.
What are signs of decreased cardiac output?
A decrease in cardiac output is characterized by the following manifestations:
- Abnormal heart sounds (S3, S4)
- Angina.
- Anxiety, restlessness.
- Change in level of consciousness.
- Crackles, dyspnea, orthopnea, tachypnea.
- Decreased activity tolerance.
- Decreased cardiac output.
What is the normal resting cardiac output?
A healthy heart with a normal cardiac output pumps about 5 to 6 liters of blood every minute when a person is resting.
What is low cardiac output?
Low cardiac output syndrome (LCOS) is a clinical condition that is caused by a transient decrease in systemic perfusion secondary to myocardial dysfunction. The outcome is an imbalance between oxygen delivery and oxygen consumption at the cellular level which leads to metabolic acidosis.
What is the difference between BSA and BMI?
While Body Mass Index (BMI) is a measure of a person’s body fat mass, Body Surface Area measures the total surface area of a person’s body and is frequently used in order to calculate drug dosage and the amount of fluids to be administered by IV.
How do you calculate BSA without height?

What is BSA Biochem?
Bovine serum albumin (BSA or “Fraction V”) is a serum albumin protein derived from cows. It is often used as a protein concentration standard in lab experiments.
