Instructions on Using Nathan's Chart


Nathan's Chart is designed to be simple to use. I recommend just playing around with the application, and you can teach yourself within 10 minutes. If you need further instructions, please read the below which breaks up the application into each section.

1. Units of Measure

Choose 1 radial button based on your preferred unit of measure. You may choose fluid ounces (fl oz) because your doctor says to take “12 fl oz. per day” of food. For Nathan, we use calories since we want to reflect that the food he is given is 45 calories per ounce. Depending on what you select, the headings in each section will change to reflect your choice. Choose different radial buttons and watch how the headings update.

2. Total Amounts

The food and water amount in this section will be given to you by your doctor. Nathan’s pediatrician and gastroenterologist both give the amounts needed each time we have an appointment for Nathan based on his current weight. Sometimes it is based on weight, height and age. The amount for food defaults to 500 and the amount for water defaults to 300. For Nathan, he currently gets 300 mLs of food, so I would put 300 in the first box labeled ‘food’. Nathan also needs 600 mLs of water over 24 hours, so we put ‘600’ in the second box labeled ‘water’.

3. Default Water Flush

This section is optional depending on whether or not you need to keep track of water given while flushing the tube. We give Nathan water throughout the day without using the feeding pump. We usually give Nathan 30 mLs each time we flush, so we put 30 in the box labeled ‘water’.

4. Reset Button

The Reset button will delete any value you have entered in the entire page and reset the values to a standard set.

5. Menu Planner

This section simulates a feeding pump machine. You can select the pump rate using the slide bar. You can use the arrows on your keyboard to help get to a desired number on the bar. There are 3 columns to choose from: food, water and water flushing. For Nathan, each meal he gets is a dose of 100 with a pump rate of 185. Next, select the ‘Add Meal’ button. Once you select to add a meal, the below dialog box appears for you to select a time for the meal. Once a time is selected, the meal will appear in the Daily Menu section. You can also add water and oral meals in this section.


6. Daily Menu

Each time you add a meal, water, or oral meal from the Menu Planner, it will appear in the Daily Menu section. It will list them in order of time, and it shows how long the meal will last. It displays the pump rate and food or water amount. It will keep track of the amount of food consumed or remaining while you are planning the menu. There is also a progress bar in orange and turquoise to show the % complete for a 24 hour period. On each row, there is an option to delete that row, so you do not need to start over if you make a mistake. On the water row, if the water meal is a water flush, there is an asterisk to indicate this. The asterisk also shows in the printed version of the daily menu.

7. Print

The Print button allows you the Print the Daily Menu that you have completed. When you hit the Print button, a dialog box will pop up to have you enter the name of the person on the feeding tube which will appear on the top of the printed Daily Menu. It also has a Special Instructions section to allow you to write any message you want. We write Nathan’s medicine schedule in the window.


Once you select the Accept button, the printer dialog box will appear and you can print the final daily menu. Please share this menu with caregivers, teachers, doctors, therapists, parents, baby sitters and siblings, or whoever may need to know this information.
