Periodic Check Items and Procedures
Perform the periodic check according to the following list.
 The periodic check should be performed once a year.
 The "Periodic Check List" is on the last page of this manual.
 If the equipment fails any check item on the periodic check list, the general judgment will be "Fail". Repair the
equipment so that it passes all the check items.
 Use the equipment only if the judgments for all the items are "OK".
 Check all cables, equipments, accessories, earth impedance, leakage current, and accuracy.
CAUTION
 Before the check procedure, back up the setup data and patient data on a CF card.
 Some models of commercially available bench top functional testers and patient simulators
can be used to verify the proper functionality of SpO
2
monitoring system, sensors, cables,
but they are incapable of properly evaluating the SpO
2
measurement accuracy. SpO
2
measurement accuracy can only be evaluated by comparing measurement data with SaO
2
measurements obtained from simultaneously sampled arterial blood using a laboratory Co-
oximeter.
