treatment not working

my husband has pneumonia & a staph infection.  He is not getting any better at all. He is on ventilator.  The hospital has him all sorts of antibiotics.  Why is  he not getting any better?

Watch his food & drink intake.  Is he drinking anything with artificial sweetners?  They can cause horrible side effects.  (look under Heart disease on forum to see a full posting) or on line under Aspartame side effects.
Are they giving him vitamins to boost his system? Like B-complex, C, etc..
Nutrition is so many times over looked by doctors in their rush to just medicate.  Hopefully you'll get some more suggestions.  good luck & God Bless

The man is on a ventilator, he is not eating or drinking. He gets fluid from IVs.  She needs to talk with his doctors about how many days of antibiotics might it take for them to combat his infection and what do they plan to do if he continues to not improve.
