At first, you start by taking a picture of the kid on a hospital bed, then, using AI, the app recognizes the corners of the bed and what it estimates as the kid’s height. If the kid’s height is not correct, you can move the bar that displays what the app perceived as the correct height, and place it where the correct measurement would be.
After making sure the kid’s height is correctly measured, you need to fill out basic information needed to calculate the patient’s measurements and doses. After filling the form you can submit all of the information, and the app calculates the kid’s height, weight and doses on its own.
