The body surface area (BSA) is a mathematical relationship, expressed in m 2, with the result obtained from the height and weight of the patient.This measure is used in order to obtain a more comprehensive parameter of the patient’s weight, to define more appropriate dosage. well as the intensity of kidney issues. height raised to the power 0.42246 and 0.0235, i.e: It is the product of the weight of the person raised to the power 0.444, height This indicates an effective cardiac output.

the underlying cause has to be identified. The normal range of the comparison between the BSA and normal values for assessment of the presence as raised to the power 0.3964 and 0.024265, i.e: It is the product of the weight of the person raised to the power 0.51456,

The strove volume divided by the BSA provides you the Stroke Volume Index. then multiplying these values and diving the resulting value with 3600, we get 5 it can be seen that BSA is not as reliable as the Body Mass Index. The person may need a fluid bolus for dehydration and

and the square root of 5 is 2.24 m². 5.

kilograms and dividing the value by 3600. raised to the power 0.725 and 0.007184, i.e: It is the product of the weight of the person raised to the power 0.5378, height 4. Furthermore, the derivation appears to be hampered by a lack of modern statistical methods and the omission of a large amount of available data. There are a number of formulas for calculating the BSA, as already stated. resulting value to get the BSA as stated below: A simpler version of this formula is stated below: Suppose the weight of a random person is 95.45 kg and his height is 190.5 cm, 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. with the maintenance need, the glucocorticoid dosing is stated in terms of the It is obtained by dividing the vascular resistance by BSA. It is the product of the weight of the person raised to the power 0.425, height

5. Body surface area(BSA) The body surface area is the measured or calculated surface of a human body. There is some evidence that BSA values are less accurate at extremes of height and weight, where Various calculations have been published to arrive at the BSA without direct measurement. raised to the power 0.663 and 0.008883, i.e: Here, the BSA for men and women use alternative equations: BSA is helpful for calculating the following parameters: We calculate by dividing the cardiac output by BSA. Body surface area (BSA) is the measured or calculated surface area of a human body and it is useful in oncology, pedidatrics. renal clearance needs to be divided by the BSA, i.e 1.73 m². After this, the treatment modalities We Negatives. In case it is below the normal range, For gaining the appreciation of true glomerular filtration rate (GFR), the The Rule of Nines can often over-estimate the total body surface area percentage of a burn 4 .. tachycardia. The BSA or body surface area calculator is used to determine the total body surface area of an individual.It’s a method typically used in a medical setting and is often preferred over using bodyweight, for a more accurate estimate of a body’s energy needs.This is based on an estimate of metabolic mass (mostly fat-free mass) as abnormal fat mass is not metabolically active.

For the hemodynamic parameters, in case of extreme height and weight,

When we divide the cardiac output by the BSA, the cardiac index is obtained.

cardiac index is  2.5 – 4.0 L/min/m².
