Conrm the enFlow and the ECG monitor are plugged into dierent outlets

There are two reasons for this action. It is possible that the two systems are in an electrical phase related conict, which is being expressed on the monitor.

Secondly, it is possible that the outlets are not properly grounded or grounded in dierent locations. While rare, it can be the case and outwardly there would

be no way to tell.

Conrm the Warmer cord is not entwined or near the ECG lead cable

Separating the two cords will allow each cable’s shielding to work to its full potential.

Conrm the monitoring cables and lead wires are in proper working order

The insulating layer on lead wires and cables degrades over time and with use. Conrm the insulation is intact and operates at its stated specications.

Review the monitor’s notch lter

Check to ensure that the monitoring system’s frequency lter is set appropriately.

Determine the monitor’s sensitivity setting

Many physiological monitors have the ability to interpret electrical signals in two distinct modes: a highly sensitive “Diagnostic” mode or a more ltered

“Monitoring” mode. Determine the current mode of operation. If the current mode is set on “Diagnostic” consider adjusting it to “Monitoring.”

Check the ECG pads impedance

Contact your current supplier of monitoring pads or your local Vital Signs representative to determine if a lower impedance version is available. High

impedance monitoring pads are less sensitive to the very low signal strength from the heart beat and appear to be more prone to pronounced interference.

enCheck (Model 400) user guide

Intended use

Use this product only for the purpose for which it was designed; refer to product description below.

Purpose

The enCheck tester was developed to quickly and reliably trigger the over-temperature alarm condition on the enFlow Warmer. Within seconds, the enCheck

unit will heat the Warmer to an over- temperature scenario causing the alarm to sound. Additionally, the enCheck is designed to verify the Warmer operation

at enFlow’s installation site.

Procedure

When the enCheck is connected and running in the normal mode, the heat is generated from the Warmer unit using the same technology as when a

cartridge is installed. This mode allows for conrmation of the temperature output of the Warmer. (See Appendix E, section on “Simulated Use Performance

Testing.”)

enCheck system description

The enCheck is designed to verify the Warmer operation at enFlow’s installation site. In the Normal Mode, it allows for conrmation of the temperature

output of the Warmer. In the Overheat Mode, it heats the Warmer to an over-temperature scenario causing the alarm to sound.
