What does body surface area tell you?

Body Surface Area (BSA) BSA measures the total surface area of the body and is used to calculate drug dosages and medical indicators or assessments.

What is a normal body surface area?

The “normal” body surface area is generally taken to be 1.7 m2 but, in actual fact, the body surface area depends on more than just height and weight. Other influential factors include the age and gender of the individual. For example: Average body surface area for adult men: 1.9 m2.

How is body surface area calculated?

Body surface area: BSA. The total surface area of the human body. 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 percentage of your body is your face?

The front and back of the head and neck are 21% of the body’s surface area. The front and back of each arm and hand are 10% of the body’s surface area. The chest and stomach are 13% of the body’s surface area. The back is 13% of the body’s surface area.

What is the importance of body surface area?

Clinical Significance Body surface area is also useful to assess the degree of severity in severe burn injury patients. It is crucial to accurately assess the percentage of total body surface area that a patient has sustained burns to stratify the severity best and guide the management of patients with burn injuries.

What is the importance of BSA?

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 BMI and BSA?

Key Difference: BMI, abbreviation for Body Mass Index, is a body measurement technique that measures the body’s weight in relevance to its height. BSA stands for body surface area, and as its name suggests, it measures the body’s surface area. They help measure the body to see how healthy it is.

Why do infants have a higher body surface area?

The body contains 2 major fluid compartments: the intracellular fluid (ICF) and the extracellular fluid (ECF). Infants’ and children’s higher body water content, along with their higher metabolic rates and increased body surface area to mass index, contribute to their higher turnover of fluids and solute.

What is your heaviest organ?

What’s the largest solid internal organ? The largest solid internal organ is your liver. It weighs approximately 3–3.5 pounds or 1.36–1.59 kilograms and is about the size of a football. Your liver is located beneath your rib cage and lungs, in the upper right area of your abdomen.

What is your skin made of?

Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

What is the difference between BSA and BMI?

What is BSA in medical?

Values for body surface area (BSA) are commonly used in medicine, particularly to calculate doses of chemotherapeutic agents and index cardiac output. Various BSA formulas have been developed over the years.
