Once upon a time...
.
A person in a coma has to be fed. They don't wake up to eat and then go back to sleep. These people are usually fitted with a feeding tube, and the giving of nutrition becomes a medical aspect of their care.
FEEDING TUBES ARE MEDICAL!
Formula is used for nutrition. The "drink" is this formula. Patients don't drink it at all. Rather, it is personally delivered by a feeding-tube. A person dies without food. The formula has all the nutrients of food. If given the formula, a patient who cannot eat will live, usually. Other medical problems may occur, but feeding tubes are meant to avoid starvation.
My formula happens to be Ensure. It is sold at the local grocery store. In an emergency I could get some. The containers look different on the outside, but that is marketing. I get the wholesale medical cartons from a supplier, not the fancy bottles sold in stores. Marketing now has all kinds and flavors, but I take the good, ol' original. Going back in history, it may have been the original formula.
I bought this on-line.
"Bleh," is all I can say about the unflavored formula given at one hospital. I get "You can taste?" Yes, I can taste, and tasting unflavored feeding placed directly in the stomach is not instant. I have reflux. I'll instantly taste it if it comes back up. It's usually vomit by then. Tasting unflavored formula and barf is not pleasant.
Recently I saw a science video talking about holes in the body. I guess if you rub a raw, cut clove of garlic on the sole of your foot, you taste garlic an hour later. In the same way, give me coffee flavor Ensure and I taste cheesecake an hour later. I assume digestion has something to do with the flavor.
The formula has to make it's way into the body. This is how it becomes a medical procedure.
The feeding tube is a port into the body through the stomach. Likewise, an IV is a port into the body through a vein. There also is special tubing and usually a bag to hold the substance. These are medical supplies and not food.
Sometimes there is a pump. I do not have one. I have a Feeding/IV Pole, and natural gravity becomes the driving force of moving the formula.
Learning to Taste
My favorite flavor was Butter Cream Frosting. I believe it was this brand, and I doubt they still make it. This picture was on E-Bay and the product is probably discontinued.
During 2003-2006, while still in the hospital, I taught myself how to taste. How you ask? I used the flavored lip-glosses and lip-balms for children. I had a ton. I couldn't eat. I'd put on a flavor when I had a tube-feeding.
Applying and opening/closing lip balm became Occupational Therapy. I was careful to remove lids over my lap. Retrieving a lid that rolls under something could be impossible.

I know how important the feeding-tube is for survival.

I watch my feeding-tube like a hawk. I got it 18 yrs ago. I should have died 18 yrs ago. It kept me alive for 2 years while waiting for life-saving surgery. I breath on my own; I speak on my own; and I now write on my own. That feeding-tube has kept me alive. (It's not the same tube. I periodically have it changed to prolong life.)
I know how to temporarily reinsert the tube until medical care arrives. I know how to provide daily care to keep it maintained. A person in a coma can not coordinate their care. A service coordinator is needed. Emergency services can be provided by a nurse.
There is a difference between food/formula and medical supplies. A conscious, aware person, with knowledge can serve as coordinator.
The lollipop thing I do is something I dreamed up all by myself. I'll need to explain, or me eating anything will look like a miracle. I used to provide early intervention and I also did the job of disabled services coordinator. The lollipop training I do comes from these experiences.
My formula and feeding supplies were once cut off by the government. They required a swallowing evaluation.
I thought that if I could only swallow the formula, then I wouldn't need any supplies. Then I thought, "I can do that, sort of." When I did Early Intervention a few kids had eating problems. I'd use my experience.
________________
I haven't had food in a long time. Lollipops are used in a patient that can handle their saliva but cannot swallow food. This is why I use lollipops. The goal is only formula intake.
Swallowing would be an outcome. This now happens to be the issue that determines me being vegetative. We'll see what happens.
I have somewhat of a swallow now, but nothing that would pass a test. It needs to be stronger and more consistent. I continue with lollipops.
If you say it's slow...
