1) Does the PD catheter take a long to be ready? Can I wait until I start feeling poorly to do the surgery?
Looking back at my calendar, three weeks passed between the time they installed the PD cath(s) and when I started moving any fluid at all, and then it took time to work its way up to my full amount. Remember, you'll start out doing things manually and they have to test whether your P does D fast enough to use a cycler. So the basic answer is no. By the time you feel poorly (by which I mean edema and vomiting) it will be too late to wait three weeks and they'll stick a hemo cath in your chest.
2) Can you shower with PD?
Once it's healed, yes.
3) Do you feel well enough to work 40 hour weeks in a office desk job environment with no physical activity?
Yes. Oh, and a warning about the default machine settings: By default the cycler is designed to take as long as it takes to do the cycling and dwells, so it will make you late for work. Change the settings so that it will stop after the allotted time and just make a note of how much time you missed. If it's just a couple of minutes it's no big deal, but if you're losing a significant amount of dwell time it matters. Just calculate the percentages and tell your nurses.
4) Is the machine loud at night?
There are different parts to the cycler's annoyance. The first is that it vibrates. You can make this less obnoxious by setting it on some sort of vibration-dampening material. I used a padded laptop sleeve that I wasn't using and that cut the hum way down. The second is that the display is very bright, but you can adjust the brightness of the display. Check the manual. Finally, you can turn down the alarm, which won't help much, but if you also tape a big hunk of gauze over the speaker grill it will make it a more reasonable volume.
5) I read for night time PD with machine, you have to be in bed for 10-12 hours. Can you do other activity in bed during that time like eat/read?
That's not technically correct. You have to be attached to the machine while it is moving fluid in or out, and that's it. My strategy was to set up the machine while dinner was cooking so it could do the self check and warm up the bags while I was doing something else. Then I would hook up for the first exchange then unhook and have about 2.5 hours of freedom. Then I'd hook up again before bed. You'll hear that unhooking is for emergencies, but so long as you don't contaminate anything you'll be fine. In bed you can do anything--eat, drink, read, have sex, watch tv, work on the computer, whatever.
6) Is there a machine to help you do PD exchanges during the day?
Nope. That one goes manually.
7) For daytime PD exchange, do you just sit in a bathroom for half an hour to do the exchanges?
Not a chance. I sat in my office and did the exchange at my desk while working away on the computer. If someone came by maybe I'd say something lame like "Excuse me while I tap a kidney." If I was being cruel I wouldn't explain anything. I kept my door closed while doing anything sensitive like connecting, disconnecting, or prepping bags for injections. (I kept a shoebox with all sorts of useful things on my shelf.)
