How is body surface area classified?

It is not only height and weight that determine BSA. Age and gender make up the rest of the factors. Here are the classifications:
  • BSA is 1.9 m2 on average for adult men
  • For adult women, it is 1.6 m2
  • It is 0.25 m2 for newborns, 0.5 m2 for 2-year-olds, 1.14 m2 for 10-year-olds, and 1.33 m2 for 12-13-year-olds.

Are there any parameters that require for BSA calculation?

The BSA can be used to calculate the following parameters:
  • CI (Cardiac Index): Divide the cardiac output by BSA to calculate the cardiac index. The normal range for the cardiac index is 2.5 – 4.0 L/min/m2. An individual with an index below the normal range needs to be identified to determine the underlying cause, and treatment options must be chosen. A fluid bolus may be necessary if the individual is dehydrated or has tachycardia. An inotropic agent may also be necessary for heart failure.
  • SVI (Stroke Volume Index): Stroke Volume Index is calculated by dividing stroke volume by BSA.
  • SVRI (Systemic Vascular Resistance Index): You can calculate the SVRI by dividing the systemic vascular resistance by the body surface area.
  • PVRI (Pulmonary Vascular Resistance Index): The vascular resistance is divided by BSA to obtain this value.

Exactly how does BSA work?

Here are some things you can do with BSA:
  • The dose of chemotherapy is determined by it.
  • The glucocorticoid dose is expressed in terms of the BSA so that you can calculate the maintenance doses.
  • It's important to divide the renal clearance by the BSA to get a true glomerular filtration rate (GFR)
  • There's also an index called the Quetelet index that's modified from the BSA.
  • It tells us the effective cardiac output when dividing the cardiac output by the BSA.
  • BSA does not provide a reliable measure of hemodynamic parameters if height and weight are extreme
  • As part of assessing the presence and intensity of kidney issues, this parameter adjusts the creatinine clearance while comparing the BSA and normal values.

What is the clinical significance of BSA?

In pharmacology and physiologic data measurement, body surface area plays an important role. In chemotherapy, body surface area is most used to guide dosages. Researchers found that chemotherapy had a much more consistent effect on cancer treatment patients when dosed based on body surface area rather than body weight. Severe burn injury patients can also be assessed based on their body surface area.

To stratify a patient's severity and guide their management, it is essential to know what percentage of the patient's total body surface area has been burned. The body surface area can be used in part to calculate physiological information. It is also important to use body surface area to calculate the physiologic status of the heart by calculating the cardiac index. Several clinical tools, such as nomograms, calculate body surface area by using the height and weight of the patient graphically.
