## What is BSA formula?

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.

**How do you calculate the BSA of a child?**

Abstract. We retrospectively compared body surface area (BSA) using the Mosteller formula square root(H x (w/360)) and a simple weight-based BSA formula ([4Wkg+7]/ [90+Wkg]). The participants were 363 children who underwent cardiac surgery from 1991 to 2000.

### How do you prepare BSA standards?

Mix 50 μl of the BSA standard solution (2 mg/ml) with 950 μl of diluent and mix well to prepare a 0.1 mg/ml BSA standard solution. Prepare 2 sets of the dilutions of BSA standard solution as shown below 1.5 ml microtubes (7 types x 2 sets = 14 microtubes).

**What does the copper sulphate react with in the Lowry protein assay?**

The Lowry protein assay uses copper, which bonds with the peptide bonds in proteins under alkaline conditions. This forms a monovalent copper ion which can then react with the Folin reagent, which in turn can be reduced into a blue colored substance. Thus, the concentration of protein can be determined.

## How do you calculate total body burn in surface area?

Estimating burn size in adults See a picture of the “rule of nines” for adults. The front and back of the head and neck equal 9% of the body’s surface area. The front and back of each arm and hand equal 9% of the body’s surface area. The chest equals 9% and the stomach equals 9% of the body’s surface area.

**How do you figure surface area?**

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

### What are the 9 Rules of burns?

Rule of nines for burns

- The front and back of the head and neck equal 9% of the body’s surface area.
- The front and back of each arm and hand equal 9% of the body’s surface area.
- The chest equals 9% and the stomach equals 9% of the body’s surface area.
- The upper back equals 9% and the lower back equals 9% of the body’s surface area.

**What is Folin Lowry method?**

Lowry Method Lowry adds phosphomolybdic/phosphotungstic acid also known as Folin-Ciocalteu reagent. This reagent interacts with the cuprous ions and the side chains of tyrosine, tryptophan, and cysteine to produce a blue-green color that can be detected between 650 nm and 750 nm.

## What is the nine rule in math?

The divisibility test that an integer is divisible by 9 iff the sum of its digits is divisible by 9. SEE ALSO: Casting Out Nines, Divisibility Tests.

**What are numbers divisible by 9?**

If the sum of the digits of a number is divisible by 9, then the number is divisible by 9. Some examples of numbers divisible by 9 are as follows. The number 51984 is divisible by 9 because the sum of its digits 5+1+9+8+4=27 is divisible by 9.

### Why is BSA used?

BSA is used because of its stability to increase signal in assays, its lack of effect in many biochemical reactions, and its low cost, since large quantities of it can be readily purified from bovine blood, a byproduct of the cattle industry.

**What is a good BSA?**

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.

## How do you calculate BSA in Excel?

Using their example a height and weight of 121cm and a weight of 25 the BSA calculates at 0.92. On my formula in Excel: =SQRT(X172*N172)/3600 I get 0.12.

**How do you calculate 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.

### What two numbers add to 9?

2 + 7 = 9, cross out 2 and 7. 2.4 + 3 = 9, cross out 4, 3 and 2. 3. There are no other groups of numbers adding up to 9.

**How do you calculate BSA on a calculator?**

A formula to estimate the approximate surface area if height and weight be known….meters inches.

Body Surface Area | |
---|---|

Formula : | BSA (m2) = |

Mosteller : | = √ height (cm) x weight (kg) 3600 |

DuBois & DuBois : | = 0 |

## What is the rule of 9 in ASL?

The Rule of 9 in American Sign Language (ASL) is a term that describes a rule or pattern in numeral incorporation that a number only up to 9 is incorporated with a regular sign, usually related to time with a few exceptions. This can be done with a number between one and nine, but not beyond 10. That’s the Rule of 9.

**Why is it called the rule of nines?**

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 |

### Which amino acid is not targeted in Folin Lowry method?

Advantages: The Folin reagent reaction with intact proteins is relatively constant from protein to protein (Dorsey et al., 1977) and it does not react with free amino acids except tyrosine and tryptophan.
