If you need total sofa score and you already have cardiovascular system, respiratory system: pao2/fio2, liver: bilirubin, kidneys: creatinine lv / urine output, central nervous system: glasgow coma scale score and coagulation: platelets, this calculator does the substitution for you. It suits a quick check, a homework answer you want to confirm, or any figure you need to sanity test.
What Is the SOFA Score Calculator?
The sofa score calculator gives you an estimate of total sofa score based on cardiovascular system, respiratory system: pao2/fio2, liver: bilirubin, kidneys: creatinine lv / urine output, central nervous system: glasgow coma scale score and coagulation: platelets.
It is a quick reference figure rather than a diagnosis, and it is most useful for tracking how a number moves over time rather than for interpreting a single reading.
How the SOFA Score Estimate Is Worked Out
The calculation follows published reference relationships, so it is a reasonable approximation when the inputs are accurate. It assumes an average adult and does not account for individual variation.
If you are comparing two people, or the same person over a period of weeks, keep the method and the inputs identical. A change in the method can easily look like a change in the person.
What This Calculator Does Not Do
It does not diagnose anything, and it does not replace advice from a clinician. If a figure comes out at an extreme, or if it differs sharply from what you expect, that is a reason to speak to a professional rather than to adjust the inputs.
Nothing you type here is stored or sent anywhere. The whole calculation happens in your browser.
A Worked Example
Working through an example, with cardiovascular system set to 0.000000000000000, respiratory system: pao2/fio2 set to 0.000000000000000, liver: bilirubin set to 0.000000000000000, the calculator returns total sofa score of -. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out total sofa score?
Enter cardiovascular system, respiratory system: pao2/fio2, liver: bilirubin, kidneys: creatinine lv / urine output, central nervous system: glasgow coma scale score and coagulation: platelets. The calculator then works through the relationship and reports total sofa score.
What does the sofa score actually calculate?
It takes cardiovascular system, respiratory system: pao2/fio2, liver: bilirubin, kidneys: creatinine lv / urine output, central nervous system: glasgow coma scale score and coagulation: platelets and converts them into total sofa score using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter cardiovascular system?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
Can I use this for a quick estimate as well as a precise answer?
Yes. The calculator is built for quick checks, so round your inputs to a sensible number of significant figures and the result will be just as useful. If you need more precision, keep the same method and add digits to the inputs rather than adjusting the method itself.
