The apache ii calculator works out apache ii score from a a gradient, age, creatinine, fio2, glasgow coma scale, heart rate, hematocrit, mean arterial pressure, arterial ph, pao₂, potassium (k⁺), renal failure, respiratory rate, sodium (na⁺), surgery required, temperature and white blood count. Enter what you have and the relationship is applied straight away, so you get the answer without working through the algebra yourself.
What Is the APACHE II Calculator?
The apache ii calculator gives you an estimate of apache ii score based on a a gradient, age, creatinine, fio2, glasgow coma scale, heart rate, hematocrit, mean arterial pressure, arterial ph, pao₂, potassium (k⁺), renal failure, respiratory rate, sodium (na⁺), surgery required, temperature and white blood count.
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 APACHE II 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 a a gradient set to 4, age set to 10, creatinine set to 10, the calculator returns apache ii 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 apache ii score?
Enter a a gradient, age, creatinine, fio2, glasgow coma scale, heart rate, hematocrit, mean arterial pressure, arterial ph, pao₂, potassium (k⁺), renal failure, respiratory rate, sodium (na⁺), surgery required, temperature and white blood count. The calculator then works through the relationship and reports apache ii score.
What does the apache ii actually calculate?
It takes a a gradient, age, creatinine, fio2, glasgow coma scale, heart rate, hematocrit, mean arterial pressure, arterial ph, pao₂, potassium (k⁺), renal failure, respiratory rate, sodium (na⁺), surgery required, temperature and white blood count and converts them into apache ii 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 a a gradient?
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.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
