## How do you calculate body surface area for a burn?

The Wallace Rule of Nines is a clinically efficient and accurate method to calculate the total body surface area of a burn….What is the Wallace Rule-of-Nines?

Rule-of-9s | Total | Subdivision |
---|---|---|

Head | 9% | Anterior Head = 4.5% Posterior Head = 4.5% |

Torso | 18% | Chest = 9% Abdomen = 9% |

Back | 18% | – |

**How do you calculate body surface area?**

The most commonly used formula now is that of Mosteller, published in 1987 in The New England Journal of Medicine. 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.

### How do you calculate the extent of a burn?

The rule of nines is meant to be used for: second-degree burns, also known as partial-thickness burns. third-degree burns, known as full-thickness burns….What is the rule of nines?

Body part | Percentage |
---|---|

Head and neck | 9 percent |

Legs (including the feet) | 18 percent each |

Posterior trunk (back of the body) | 18 percent |

**What is a good 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 women: 1.6 m2.

#### What is the Dubois formula?

Du·Bois for·mu·la (dū-bwah’), a formula for predicting a person’s surface area from weight and height: A = 71.84W0.425 H0.725, where A = surface area in cm2, W = weight in kg, and H = height in cm.

**What are the two categories of burns?**

What are the classifications of burns?

- First-degree (superficial) burns. First-degree burns affect only the outer layer of skin, the epidermis.
- Second-degree (partial thickness) burns.
- Third-degree (full thickness) burns.
- Fourth-degree burns.

## What are the 3 types of burn?

What are the types of burns?

- First-degree burns are mild (like most sunburns). The top layer of skin (epidermis) turns red and is painful but doesn’t typically blister.
- Second-degree burns affect skin’s top and lower layers (dermis).
- Third-degree burns affect all three skin layers: epidermis, dermis and fat.

**What is body surface area?**

Body Surface Area (BSA) is simply a measurement of the surface area of your body. Since the body is a complex figure, making an accurate measurement of its surface is a considerable challenge. To address it, scientists in the early 1900s took measurements via melted paraffin and paper strips applied to their body.

### What is the surface area of the body?

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.

**What is the surface of the human body?**

The surface areas for adult humans range from 1.3 square meters (4’10” and 90 lbs.) to 3 square meters (6’3″ and 370 lbs.), and everything in between. Body surface area doesn’t indicate the body type of an individual.

#### What is the surface area of a burn?

Surface area of the skin: The total area of the body surface covered by the skin is about 2m 2 in adults, and the skin thickness varies between 0-3 mm and 3mm. The assessment of percentage of skin-covered surface area is important in the treatment of extensive burns. It roughly follows ‘the rule of nines’ and is expressed as follows;
