The Patient Session
3-22 ST80i Stress Test System Instructions for Use
Power on/off the PIM
Check PIM battery status, wireless link quality, and lead contact quality
When requested to check battery status, the wireless PIM will provide indication of estimated
battery power remaining.
When requested to check status of connection to the host system, the wireless PIM will
indicate relative signal strength based on the measured signal quality for the link to the host
receiver.
When requested to check lead/electrode connections, the wireless PIM will indicate “Poor
Lead Signal Quality” condition for any patient electrode connection where the measured
impedance is considered excessively high for good quality, low noise ECG measurements.
You are able to check the lead signal quality of lead connections while hooking up and
preparing patient in an area outside of the range of the system’s radio connection.
