I find that after I let the machine cycle for a few minutes after the inital prime that clamping the arterial (red clamp) for a second or so does wonders for clearing micro bubbles.With the 171 cartridge you can leave the red clamp closed for quite awhile but clamping for just a second or two makes snap and tap go much easier.If I wasn't doing nocturnal I don't think I could stay on NxStage, a short daily schedule is a grind.
I'd love to see data backing up your "usually" assertion.
The web based calculator can be used by your nephrologist to figure out how to change your settings to get better hours. For example an increse in the flow fraction can speed up the dialysate to get the 30 liters in much faster than current time . The flow fraction can go quite high. The fastest dialysate rate is 12 liters per hour. With the machine at max, 30 liters would only take 2.5 hours. There are ways to do it easily including fewer days. Your nephrologist should go online to the calculator and plug in your numbers and show you the various optiions. there should be 4, 5, 6 day options and various times and speeds.

The way NxStage connected blood pump speed to dialysate speed has always been a weird quirk of the system. The issue for NxStage is the dialysate - their system limits dialysate so it is designed to make the most of each unit of dialysate. Machines like the Baby K have unlimited dialysate so they are designed to make the most out of unit of time. The complaints I hear are from people who value a unit of their time more than a unit of dialysate.It is hard for me to not feel wistful for the Aksys PHD - if it could only come back to the market as a device that was reliable and had a business savvy tech support system, like NxStage's swap out approach, which is NxStage's key innovation. The Aksys had basically no set up time day to day, high clearances from fast dialysate pump speeds and hemodiafiltration, top of class biocompatibility, big high clearance artificial kidneys ... sigh.
I'm not sure I see the point in doing a 3x/week schedule at home. The biggest reason I wanted to do home hemo was for better, more consistent treatment, hence the 5 treatments a week. If I'm going to be doing what's basically the same as in-center treatment, just at home, and I don't have the option to travel any easier, and I have to do all the setup, testing, and sterilizing myself, I don't see the benefit in that.
I've been searching for a post like this thank you all.You see I am having a horrible time with getting rid of air too.It literally takes hours. I let it go through prime, but unless I wait at least an hour idling the bubbles are horrendous. I know why and it's a temperature issue with the de-gassing. In the Northeast my house is at 68deg. The machine is 85deg. When all 3 pumps run at full speed at 2.1 they saturate the saline and it de-gasses as the temp of the saline rises. Depending on the ambient temp will dictate how bad or if this will even happen.So here's the deal.NxStage says that no one has ever complained about this before. BS, I've been complaining about it to them for over a year. I spoke with someone there a year ago and now according to them it never happened. I pushed them on it and they did admit that it actually does happen, but not often. Funny how a year ago they knew all about it. I am fighting an up hill battle for them to first acknowledge it and then fix it. They are stonewalling big time.If anyone is seeing air that goes away with time and waiting please call NxStage and ask to talk to Peter. Do not let him dismiss you and hold his feet to the fire to fix this. I am frustrated as you are that treatment takes so long. I need to do treatments in the morning and don't feel that I should have to get up at 4am to be on by 7am. Yesterday and today it took all day. Today I started prime at 9:30am and I came off at 4:30pm. Not acceptable.Whenever you have issues, please call NxStage even just as a second thought. In our area patients have been having issues with defective cartridges also. But when I and the home memo nurse call in, NxStage says they never see any other issues. Please report any and all issues so they can be fixed.Thanks in advance,Mark
