Fail-safes and alarmsMachines have a lot of fail-safes and alarm-systems. A machine will alarm to warn you and will switch off … … if the ‘arterial’ pressure falls – 95% of all alarms occur when a blood line is kinked as you roll over on it during sleep and change the pressure in it … if the ‘venous’ pressure rises – usually for the same reason … if there is a blood leak – a rare event indeed … if the conductivity (dialysate fluid ‘mix’) alters … if the temperature drifts up or downThere are lots of safety nets built into machines. All you have to do is learn to recognize and correct them. But, remember, you are taught how to do this … this is part of the training process … to know what to do if a problem arises and what to do to correct it.So … will I be awoken, time and again?No … the average number of alarms per night is 1.5/night Think of an average 60+ year old man with normal kidneys and a 60+ year old prostate! He gets up in the dark, finds the toilet, gets cold feet, bumps his shin on the furniture … and often has to do this several times a night! All an NHHD patient has to do is to shake the fistula arm, un-kink the line and go back to sleep, his feet never touching the cold floor!If all else fails, you ‘come off’ and go back to sleep … there is always the next night!… in addition, there are other devices to offer protection.NHHD procedural/monitoring safety Several features can help ensure your dialysis safety while you sleep. We either use or have considered using:… an under-machine moisture-sensing device to detect moisture on the floor if the machine leaks any dialysate fluid. We use these… an ‘electrode-impregnated tape’ which sits under catheter connectors (if catheter access is used) or around the AV fistula (especially the venous needle site) to detect any blood leakage (See FAQ section)… a clip-lock ‘connector box’ is used by some centres – these fit and clip over the catheter connection to prevent any unexpected disconnection. Though these are available – or can be made simply by any instrument maker – though we have not routinely used these and all but one of our patients has a native AVFLight-weight ‘back-slabs’ (like those that are used by some orthopaedic services to immobilize wrist injuries) can be used to stabilize and/or protect the AVF needles and their insertion sites. Though potentially useful if the AVF is near the wrist or elbow, we have not routinely used back-slabs. Indeed, we encourage our patients to sleep normally, move normally during sleep, roll and turn as sleepers do. It isn’t natural to hold the arm stiff (or to protect it unduly) during sleep … so don’t. If your needling-stabilising tapes and techniques are correct, the needles will not be pulled out during sleep. Sleep is about relaxation so, you must learn to be confident (but never cocky) about your needling and securing methods … and relax.Modem/internet technology can be used to feed machine data back to a centralized monitoring station. We do not use this system in Australia though the original Canadian program in Toronto continues to do soA bedside telephone with logged ‘help’ numbers in a one-key-speed-dial system is essential NHHD back-up Back-up must be part of the support provided by your dialysis unit On-call, trained and experienced dialysis nursing staff must be at the end of the phone. This is, in our view, a non-negotiable ‘must’ Technical staff must be available the next morning to fix machine/water problems Regular servicing is vital to keep your machine running smoothly All this must be ‘set-up’ for a program to run well and efficiently
Securing the needles worries me...Desert dancer says she uses an old sock and that sounds a good idea and I saw someone else mention that they use a lot of tape.
I also saw someone say you need a blood pressure monitor...not sure why.
I only discovered this week that you have to sleep on your back, which makes sense but that must make sleep difficult for some.
The Fresenius machine that I use will go for 5 hours on a bottle of dialysate, then you have to change over...is there a way around that?
The only problem I've ever struck on dialysis is blood clotting stopping the machine, I've fixed it by adjusting my heparin infusion but would it be a problem over the long night hours.
And do users sleep in single beds, or put another way can you nocturnal in a double bed with a partner?
I see so many different reports on frequency, I've become confused...what is an ideal nocturnal dialysis schedule...I won't go two days without dialysis (that's silly in my view) but should it be successive nights with the occasional night off or what? Speak to me, fellow night owls...please.
