To be able to keep my pressure low, the head of my bed is at 45 degrees. I am a medically necessary back sleeper. The high pressures needed when on a flat bed required me to make the 'flaps' too tight for comfort. Found a hospital bed at thrift store, like new...for $300. It has been a life saver.
Problem, while I am learning how to handle the Oracle, I am fair skinned, a former Chemo patient (made my skin like tissue paper) and the Oracle is causing problems. Got a script from the dentist for a possible infection. It helped immediately. I use a liner, put diaper paste on lips as my dermatologist recommended. That helps too.
Use a soft cervical collar to keep chin up. Then a horseshoe shaped travel pillow under head..so my neck/head stays upright. Having the head of the bed is not conducive for a straight head position.
Anyway...I need to try. I will keep you up to date, especially if it is a go! Scared and excited...
