7. Align the slot and the spindle on the crank handle with the rotor latch and hole as shown
in Figure 58 #2 above.
8. Slide the crank handle in as far as it will go. The crank latch will protrude slightly from
the crank handle (see Figure 58 #3).
9. Rotate the crank clockwise and rinse back the blood with the saline according to unit
protocol. The blood should be returned under strict visual control.
Warning! Carefully observe the venous chamber and bloodline for the presence of air. Be
sure no air will be infused into the patient.
10. Clamp the arterial and venous bloodlines and the patient's arterial and venous access
lines, and aseptically disconnect them.

Manual Circulation

To circulate the blood manually:
1. Remove venous line from clamp. Be sure no air will be infused into the bloodline. If you
are performing single-needle dialysis, remove the pump segment from the single-needle
pump.
2. Open the pump door and flip the rotor latch outward (see Figure 58 #1).
3. Align the slot and the spindle on the crank handle with the rotor latch and hole as shown
in Figure 58 #2 above.
4. Slide the crank handle in as far as it will go. The crank latch will protrude slightly from
the crank handle (see Figure 58 #3).
5. Rotate the crank clockwise at a rate of 6–10 rotations per minute. This is equivalent to a
blood flow rate of 60–100 ml/min. Observe the venous chamber and bloodline to ensure
that no air is infused in the patient. Manual circulation time is the responsibility of the
clinic's medical supervisor.
Warning! Carefully observe the venous chamber and bloodline for the presence of air. Be
sure no air will be infused into the patient.
