If I understood what you are saying, we call that part of the treatment "rinse back". I would NEVER under any circumstances allow anyone to squeeze the bad of fluids to rinse back my blood. You don't know the pressure you are getting and you don't know if there maybe a chance of getting air in the lines. If your machine is alarming, that means there is a problem. You must stop and identify the problem, and address that problem. I may be the only one that feels this way, but being a dialysis RN of many years, I would never allow anyone to use pressure on a bag of saline. I don't know.... maybe I am being too cautious. Good luck to you!
What about a manual rinseback? I was trained to squeeze the shit out of the saline bag to return the blood. I would do this in case of emergency.
... returned by saline by removing the arterial tubing from the arterial needle, sticking the arterial tubing point (yes, in the old days they had a point, sort of) into the saline bag, ran the pump and let the saline push out the blood from the arterial tubing through the filter, all the way to the venous needle and into us.... returned arterial blood first, by stopping the blood pump, opening the saline connector, and letting gravity or squeezing the bag to push the arterial blood into the needle. That's followed with returning the venous blood with the saline open and using the blood pump to return the remaining blood through the venous tubing, the filter, and finally into your venous needle.Are one of those methods what you were referring to?
I'm not quite sure what you mean ... but let me have a moment.In the old days, with a nurse present, we (I started in a self-care unit) ... returned by air by removing the arterial tubing from the arterial needle, ran the pump and let the air push out the blood from the arterial tubing through the filter, all the way to the venous needle connector. But not into the patient!
We call it "Wash back". We were taught 2 methods. The best way is to connect the arterial line to the saline bag and start the pump. This way you get back as much blood as possible. The other way is called "running back via closed circut". This is usually done if you cannot disconnect the lines quick enough. All it is is you unclamp the saline, clamp the arterial, and start the pump. After that is done, unclamp arterial and gravity runs the blood back. I don't run back the arterial line as there is no air or clot catcher.
