So glad to hear pulling off all that water helped reduce your edema! Using the reds are a great fix when your edema's caused by dialysate absorption. On the two separate occasions my dad suffered edema from absorption (due to long dwells), we temporarily had him on the red bags for about 2-3 days. Each night he was pulling out 3000 mL of UF! And right after seeing improvement we IMMEDIATELY dialed him down to 2.5 (green) bags to continue removing fluid (which was 2000 mL UF per night). As a standard now, we do a mix of greens and yellows, depending on his weight fluctuations. My nurses and the people here can't emphasize enough how important it is to consider the red bags as a very short term, temporary treatment! From what I've read and heard, you can do some damage to your peritoneal membrane if you use the reds for a prolonged period. And once you do that, PD is no longer an option.
BTW, you probably already know this, but if you're on a cycler the STAT DRAIN option is your friend! I use it a lot on my dad when he's out of breath and wheezing due to feeling full, or when I want to give his scheduled drains a bit more "oomph."
