However, the monitor will force you to test for accuracy every 30 days.The verification filter, a specially modified blood chamber

In one minute, the screen will read either; “VERIFICATION PASSED READY FOR CLINICAL USE” or “VERIFICATION FAILED”.If “VERIF

Tighten the blood chamber into the dialyzer by twisting at the “wings” of the adapter until the luer-lock threads are covered. Excessive force should be avoided.

(If air bubbles are noted in the blood chamber during priming, remove by inverting the dialyzer and/or gently tapping the blood chamber while varying its position).Observe for leakage during the priming. If a leak occurs that is not alleviated by tightening t

(Note: occasionally when inserting the blood chamber onto a “Dry Pack” dialyzer, leakage may occur after priming which is generally alleviated by tightening the conn

Periodically throughout the treatment, the security of the connections and absence of blood tubing kinking should be verified per facility policy.EFFEC
