Im a bit confused about you asking about driving to dialysis ? If he does APD (which is PD) he will do it at home . If he does Hemo (which involves the fistula being made he will do it at the hospital)
the fitter you are , the worse it is for you!
You have not mentioned about the room you will need for the boxes of fluid and the ticky tacky you get with the cycler, have you plenty of room?
Also no one has mentioned the noise the machine makes, trust me it does. You will take a while to get use to it , but you will.
As far as supplies, a month's worth is about four stacks almost as wide as my shoulders, and stacked up to my chin for the dialysate, and then four wide boxes for the cassettes, and some various smaller amounts of space for caps etc. I also use a manual each day, so that's one more stack up to my chin.I keep it all in the garage.
