machines?
7.35-7.45 - ✔✔Normal range of pH of blood
acute - ✔✔______ renal failure is severe but often reversible.
air detector - ✔✔Air or foam has been detected by machine which
will sound the _____ _____ alarm and machine automatically clamps
off the line below the venous chamber. Blood pump stops- do not
disarm
air embolism - ✔✔How to prevent _____ _____?
,1. Test machine prior to use
2. Don't use if it fails
3. Make sure the air detector is armed
4. Keep at least 300 ml NS at all times
air embolism - ✔✔What are the signs and symptoms of an _____
_____?
-SOB
-Coughing
-Chest pain
anemia and ESRD patients - ✔✔Causes the lack of erythropoietin,
shortened life span of RBC, lack of iron absorption and blood loss
during HD
Treated with Epogen or iron supplement.
Arterial pressure alarm - ✔✔the amount of pressure it takes to "pull"
the blood from the access to get it to the dialyzer. Since it is a pull it is
negative pressure. Anything that blocks the pull will increase the
pressure which will make the _____ _____ alarm come on.
Arterial side up - ✔✔What end up on the dialyzer during treatment?
, aseptic technique - ✔✔A set of practices and procedures performed
under carefully controlled conditions with the goal of minimizing
contamination by pathogens.
Blood alarms - ✔✔pump stops, blood is no longer being cleaned, RTD
clock stops, no ultrafiltration, clotting can occur due to stagnant blood
blood clots - ✔✔these can cause _____ _____.
-not inverted
-overfilled tubes
-cold temps
-outdated blood tubes
-left too long
-pt has cold agglutinins- blood clumps when cold
-lab drawn before heparin
blood leak - ✔✔what does a _____ _____ alarm indicate and how do
you check for it?
-Fibers have broken inside the dialyzer
-Blood has crossed from blood compartment into dialysate and
dialysate (clean but not sterile) has crossed into blood.
-Confirm by checking effluent dialysate fluid (red hose) with a blood
leak strip. If positive- DO NOT return blood.
