Before attempting to use the Sechrist Millennium® in a patient care setting, you must make yourself thoroughly familiar with the instructions in the User’s Manual and all product labeling.

PERFORMANCE VERIFICATION The performance verification procedure provides a means of determining whether the Sechrist Millennium® meets its performance specifications. The procedure should be performed by qualified technical personnel and should be conducted prior to each clinical application or at least once per month, whichever is soonest. The procedure can be conducted more frequently if desired. If the Sechrist Millennium® fails any facet of the verification procedure, the ventilator should be removed from use pending further evaluation and possible service. It is recommended that hospital personnel maintain records documenting completion of the performance verification procedure.

Preliminary Setup: •

Connect the Sechrist Millennium® to an appropriate power source. (Note that both visual and audible alarms will be activated momentarily during ventilator power-up).

•

Connect the ventilator to both oxygen and medical air sources. (Check that the inlet gas pressures are set at approximately 50 psi.)

•

Connect an appropriate patient circuit to the ventilator, using a test lung, e.g. Sechrist Infant Test Lung P/N 20113.
