Today in this article I will show you how to create a convection and radiation worksheet. This is an important tool for any clinician who is required to use the Bode model.
A condensation/convection worksheet looks something like this:

Here is a quick explanation of the concept of a condensation/convection conduction/radiation worksheet. It is used to predict when a patient’s blood might be able to absorb x-rays. It is most useful for pre-hospital environments where the pressure of the atmosphere is very low. Many clinics have also started using a condensation/convection worksheet for their patients who require pre-hospital treatment. The two main variables that are measured are one patient’s blood loss and the other patient’s blood volume.
Radiation related worksheets can be generated using R(P) R(D) equations, D(P) R(D) equations, or the combined equations R(P) R(D) and D(P) R(D).
Using the simple PD-R(P) R(D) equation you can determine a conversion factor that tells you the density of blood needed for absorption of a single x-ray. To get a higher density of blood needed, you would need to give a higher blood loss. The formula for calculating the conversion factor is:
If you are uncertain of the conversion factor, you can make your own based on the density of the blood from the patient to which you are comparing. Of course if you are working with a comparison between two patients of different ages you should adjust the conversion factor so that the final density of blood you are testing is within the normal ranges. Remember that the conversion factor is related to the blood loss of the patient. Therefore if the patient has a higher blood loss you will need to give the patient a larger blood volume.
The most important thing about your condensation/convection worksheet is that it lets you decide how many samples you need to test before you can start to make a prediction. This will help you keep track of your testing and ensure that you have enough samples to give an accurate prediction of blood loss.
