One of the things to remember about the device is that there are different types of feeds that are available for use with it. These include protein feeds, carbohydrates, water, fat, minerals, and vitamins. Depending on the type of treatment needed, the pump will have different types of tubes in order to accomplish the feedings. These include NG tubes, NJ tubes, and PEG tubes. The NG tubes are the most common. Most of the devices have large displays which make it easy to view them from a distance, as well as alarm tones for different issues that could occur.
