I found that I needed to calibrate the spring scale (it has a sliding gauge that can move up and down) by weighing the empty bag and tubing and setting the scale to zero. I suppose you could add a "smidge" to account for the fluid in the lines, but at least my scale isn't accurate enough to account for that difference. When doing manuals I basically just round off to the closest 50ml anyway.
I am still pre-D, but I have to say I totally respect all of you doing home hemo and PD .... all of this seems overwhelming to me. My new fistula is two weeks old today (HAPPY BIRTHDAY, FISTULA !!) and I'm hoping I don't have to use it anytime soon ..... but I plan on starting my D in center because all of this stuff seems a bit crazy to learn. I'm sure eventually I'll 'get it' and hopefully get a chance to switch over to home treatment myself .... but I live alone, so I have that hurtle as well. YIKES.Congrats to all of you home dialysizers !!! GREAT JOB.
Wow, that's a lot. I use Fresenius and loss is minimal. Less than 20 ml.I may not be reading your post right, but it reads to me like you are charging your line and wasting into your drain bag, before you start to drain. Is that right?If so, I don't understand why you would.I do my drain first, then weigh that, then charge my line (Just a few air bubbles with Fresenius) and then start to fill.Losses are minimal. I don't do the counting thing, - just watch for air bubbles. I can purge the large ones, start to filland if another one appears I flick the switch back momentarily to purge. Great system.
I use the Baxter system too, but I only count to 3 when I'm priming the line, and that's only if I don't actually see dialysiate flow into the top of the drain bag. As soon as I see anything in the drain bag, I'm primed. Haven't had a problem with that yet.
Ok, I get it, sounds like a pain to me, would be more difficult than Fresenius in the truck/machines etc.If you look at the first pic, it shows the line, which is packaged pre-charged, so all I have to do is purge the little bit of air in the line (bubbles shown by arrow). Since 50% of that is air, there would be lucky to be 10ml of fluid goes to waste. That is always purged after I finish draining. Its controlled by the rotary dial, which has a close-up in the second pic.1/.Remove yellow cap and hook up. Release catheter clamp. Drain. Weigh bag.2/. Rotate dial to next stage, purge air bubbles with small amount of fluid.3/. Turn dial to fill, (Slow,Medium or Fast). Sometimes a small bubble travels down the tube from where it meets the bag. I watch for this then flick the dial back to purge for a second to get rid of it, then back to fill.4/. When fill bag is empty, turn to switch off position which also drives a pin into the line connector.5/. Disconnect and screw safety cap into connector (Pin punctures disinfectant solution.)
Good job! But how come you have blue clamps? Mine are red...And I only do one manual a day, it's typically just a fill. I drain when I go on the cycler at night and am empty all day.But I will weigh today when I do my setup and report back.
I did as we discussed and have the following observations:Baxter does overfill their 2L bags, at least mine are marked that there is approximately 80ml overfill in each bag.I weighed my drain bag and line before priming, and zeroed my scale with them on, effectively negating the weight of the empty bag and the line.I connected as usual, and primed the line. To do this, I drop the drain bag on the floor, put my RED clamp the fill bag, break the frangible, open the RED clamp and count to 3 while watching to see when fluid hits the drain bag. (I usually hit 3 the same time fluid hits the drain bag.)I weighed the drain bag, and the line as it's full now, and came up with less than 50ml. While I'm not this precise every time I do my manual exchange, I feel it was pretty typical of what I do every day.That said, I only do one manual exchange a day, so 50ml is pretty negligible in my overall UF. As the majority of my PD is CCPD, like Willis, my machine handles the counting for everything else. The only time I really pay attention to what is in this drain is when I haven't gotten everything off during my last cycle on the machine (but that's another thread.)If I was still doing my 4 exchanges a day, this would add up to about 200ml a day. While it doesn't appear to be terribly significant, every little bit counts!And if you'd like some red clamps, shoot me a pm and I'll trade you 3. More than happy to share.
Only because I didn't have the "Stay-Safe" adapter to fiddle with. Once, on the way north I threw it in the garbage at a gas station, but realized it and retrieved it before we left the station. WHEW

WHEWAre you talking about the part that mounts on the pole or the machine? When I had to do a couple of exchanges in the car I didn't put the valve in the adapter. I just used what came attached to the bags.
