What is nomogram scale?
A nomogram consists of a set of n scales, one for each variable in an equation. Knowing the values of n-1 variables, the value of the unknown variable can be found, or by fixing the values of some variables, the relationship between the unfixed ones can be studied.
What is nomogram method?
The Nomogram method is utilized to determine the correct pediatric medication dosage based specifically on the patient’s size. The patient’s size is identified as body surface area (BSA) in meters squared (M2). The average adult client (weighing 150 – 154 lbs) will have a BSA of 1.73M2.
Is nomogram an analog?
Nomogram: An analogue tool to deliver digital knowledge – The Journal of Thoracic and Cardiovascular Surgery.
Why do we use a nomogram?
Nomograms are designed to extract the maximum amount of information from data with the goal of providing the most accurate predictions.
What is henssge nomogram?
The Henssge nomogram technique for estimation of post mortem interval (PMI) utilizing body cooling is used worldwide by forensic pathologists (FPs) who may photocopy the nomogram from a popular source such as the textbook Knight’s Forensic Pathology [1, 2] to calculate the PMI.
How do you calculate Algor mortis?
Step 1: Calculate how many degrees were lost after the first 12 hours. Step 2: Now calculate how many hours past 12 hours the body has been dead. Step 3: Solve for number of hours past the 12 hours.
How accurate are nomograms?
The nomogram was 63.1% accurate in predicting lymph node metastases, when TUR stage and grade were used vs. 61% using TUR stage alone. The various components of these nomograms can be accessed at www.nomogram.org. The pre-RC nomograms provide only a modest increase in accuracy.
How do you use the Glaister equation?
The Glaister Equation calculates the hours passing after death as a linear function of the body temperature taken of the decedent. The equation is (98.7 degrees Fahrenheit – the body temperature of the decedent) / (1.5 degrees/hour) = PMI.
How do you convert BSA to BMI?
Body Surface Area (BSA)
- Calculate weight in kilograms: 210 pounds ÷ 2.2 = 95.45 kg.
- Calculate height in centimeters: 6 feet, 3 inches = 75 inches x 2.54 cm/inch = 190.5 cm.
- Multiply height by weight and divide by 3600. (190.5 cm x 95.45 kg) ÷ 3600 = 5.
- Take the square root of 5 = 2.24 m2
Is BSA same as BMI?
While Body Mass Index (BMI) is a measure of a person’s body fat mass, Body Surface Area measures the total surface area of a person’s body and is frequently used in order to calculate drug dosage and the amount of fluids to be administered by IV. Various formulas have been used over the last century to calculate BSA.
