One time Dr. G. mentioned respirator brain, a condition where the brain turned to jelly as a result of the patient being on a respirator prior to death. I am wondering if being on a CPAP machine would do the same thing. Thanks.
No. CPAP machines are to help keep your airways open when you sleep. They are not considered a "respirator". A respirator is a ventilator. A CPAP or Bipap machine you use at home is not a ventilator. It still requires you to make the effort to breathe, whereas a ventilator, it really doesn't matter, the machine does the breathing for you.
The "respirator brain" is a different condition. This is usually due to some form of trauma, hemorrhage ie bleeding in the brain, congestion, an overall loss of oxygen to the brain.
This has nothing to do with the ventilator, or cpap machine.
