Yes
FPOS
more than 7000! See procedure number
(page 539).
No
FPOS
less than 7000. See (ABOVE) procedure number
(page 535) to check
the Flow Pump.
BC LEAK- 3.2.0 PERFORM DIAPHRAGM LEAK TEST
WITHOUT LOOKING AWAY, NOW watch
FPRE
for up to three (3) minutes. Does it EVER, even if only
once, increase or fluctuate to MORE THAN four thousand (4000)?
Yes
FPRE
fluctuates to 4000 or more! A torn balancing chamber diaphragm is indicated. Remove the
clamp from valve #29 then replace BOTH balancing chamber diaphragms.
No
FPRE
remains ALWAYS approximately 2300! See parts a and b below:
a) A torn diaphragm is NOT indicated!
IMPORTANT!
Remove the clamp from valve #29 and
return the dialyzer lines to the shunt!
b). If referred to TESTING FOR A LEAKING BALANCING CHAMBER DIAPHRAGM, return to the
procedure that brought you here as NOTED!
Balancing Chamber Diaphragm Leak Test Theory:
Referring to the Figure below, the Flow Pump #21
delivers a highly conductive acid solution into the ‘spent’ (S) side of the balancing chambers at high pressure.
Both balancing chamber ‘fresh’ (F) sides are open to low pressure because the blue (to dialyzer connector)
line is in a bucket open to atmosphere. If a balancing chamber diaphragm is torn (right side in this case) the
conductive acid solution is forced through the hole, into the fresh side, through Conductivity Cell #7 causing
FPRE
to increase. If neither diaphragm is torn they prevent the acid solution from entering the fresh side and
FPRE
will not increase. Recirc valve #29 must be clamped to prevent its eventual opening from recirculating
the acid solution back into the hydrochamber causing
FPRE
to
increase falsely.
