This is a PHP file that I made that is compose of three types of calculators, specifically designed for calculating Intravenous (IV) Fluid infusion-related equations. One calculator is designed to get the amount of IV Fluid to infuse each hour. The second is designed to get the Drip Rate, while the final calculator is for getting the time to complete an infusion. This is a small project that I created for nurses and nurse-aspiring students.
Well, I used to be a nurse, but it seems my nursing days are over as I move into a new field now; a field so much different from the degree that I actually completed. Still, I understand how hard it is to study nursing so I think with the new fond field that I am in now, I might still be able to give little help to my nurse colleagues and future nurse colleagues.
Where is the IV Drip Rate Calculator?
The calculator is in PHP file format and runs in my server. To access the IV Drip Rate Calculator, click here.
The Source Code
I’m distributing the source code so that not only would it benefit nurses but it would also benefit aspiring Web Developers and Programmers. As to how I manage to make it work, you can read my entry here. Note, you need to create two files for this one, a CSS file (yourfilename.css) and the PHP file (yourfilename.php). To project the same PHP function, just copy the codes below and put them in your PHP file. Note, however, that PHP files don’t run on your computer without a PHP Processor or a server emulator like XAMPP or WAMP. To make your PHP file mobile-friendly, you also need to copy the CSS code found after the PHP code and put it into a CSS file. Put the two files in the same folder. Use the tools that appear at the upper right portion of the code page (ie. View Source, Print) to copy or print the codes.
