I agree with CJ, I'd try to get hospice in there ASAP. That being said, the only thing I would caution, would be to make sure you have all surgeries and equipment for her before hospice comes in, because once she is in hospice, medicare/medicaid will not pay for surgeries or equipment because they just pay a lump sum to the hospice agency and usually it is not enough to cover all of thier expenses.
As far as equipment, my husband has: hospital bed, motorized chair, rollater (which he no longer uses), bedside commode (which he no longer uses), bi-pap machine, suction device, cough assist maching, and a dynavox communication device with eye gaze attatchment.
We also had to get his PEG feeding tube surgically placed before hospice. Also any modifications to her chair are also considered "equipment related" and so I'd do them before hospice. Currently we are doing an additional control on my husband's chair in order for me to drive it (as he is having a hard time driving it), and we are replacing his current head rest, with a head rest that also has a "U" shape to support his neck and a strap across his forhead to steady his head, as his neck and all is becoming "floppy". Once that is done, he will be in hospice.
As far as bodily functions:
My husband is mainly bed ridden at this point, unless I use the hoyer lift to get him in his motorized chair.
For urine, I just use the urinal with him. I am not sure how it would go with a woman. So I don't know how much help that is to you. When my husband has to poop, he just poops in his bed (trying to lift him too many times and putting a bed pan under him is too painful for him, so I try to limit the amount of times I lift and roll him.) So once he has pooped, then I roll him onto his one side and clean him up, then put balm on his bed sores, then I roll up the soiled bedding into the middle of the bed, and put on the clean linens then roll the remainder of the clean linens and place that roll under the soiled roll. Then I roll my husband back on his back (with a big rolled lump in the middle of his back momentarily). Then I go onto the otherside and roll my husband the opposite way, pull the soiled linens off of the bed and place on the floor (I then put them in a hamper once I am done taking care of my husband), then pull the clean linens and make the rest of the bed. Then I roll my husband back on his back and pull him up towards the head of the mattress, then I lift the foot of the matress then the head of the mattress.
You can also google or youtube how to's in how to change a patient in a hospital bed, how to roll or transfer a patient , in order to maybe get a better "how to" in how to do this.
As far as linens, I have a fitted sheet, and a draw sheet and a bed pad. Bed pads can be found at like Walgreens, or your local hospital. A draw sheet is a flat twin sheet folded in half.
My husband normally wears a hospital gown and a sheet most days. I would go to your local hospital and see if they have any hospital gowns. I went to my local hospital and when a patient transfers from another hospital they normally change them into thier hospital gowns, and so the hospital gowns they come in can't be used at the new hospital and so they are normally are put into a closet never to be used. So I got like 5 for free.
As far as her chair, I would talk to where you got it from. Our equipment specialist are rigging my husband's chair with another joystick controller on the back of the chair so that I can drive it, as my husband is having a hard time driving it lately.
Hope this helps.
