Why is there a wandering baseline on my Welch Allyn CP 100 Medical Equipment?
If you observe a wandering baseline (an upward and downward fluctuation of the waveforms) on your Welch Allyn Medical Equipment, it could be due to several factors. Try these steps: * Clean the patient's skin with alcohol or acetone, especially if electrodes are dirty, corroded, loose, or positioned on a bony area. * Reposition or replace the electrodes if there is insufficient or dried electrode gel. * Help the patient relax, as oily skin or body lotions can interfere. * If wandering baseline persists due to rapid or apprehensive breathing, refer to the CP 200 or CP 100 Directions for Use Manual for instructions on turning on the baseline filter.
How to fix muscle tremor interference on Welch Allyn CP 100?
If you're experiencing muscle tremor interference (random, irregular voltage superimposed on the waveforms) on your Welch Allyn Medical Equipment, which may resemble AC interference, consider the following: 1. Help the patient get comfortable if they are tense or nervous. 2. Ensure the patient is warm to prevent shivering. 3. Check all electrode contacts. 4. Make sure the exam bed is wide or long enough to support arms and legs comfortably. If the issue continues, consult the CP 200 or CP 100 Directions for Use Manual for instructions on turning on the muscle-tremor filter. If interference still persists, the problem is probably electrical in nature; refer to the manual for reducing AC interference.
How to troubleshoot AC interference on Welch Allyn CP 100?
To resolve AC interference, check all electrode contacts and lead wires. Ensure the patient isn't touching any metal and that the AC power cable isn't touching the patient lead cable. Verify the correct AC filter is selected. If the problem continues, unplug the Welch Allyn Medical Equipment from AC power and run it on battery. If this fixes the issue, the noise is from the power line. If it persists, the noise may be from other equipment or poorly grounded power lines; try moving to another room. Dirty, corroded, or loose electrodes, insufficient electrode gel, a patient touching metal, broken wires, nearby electrical devices, or incorrect AC filter settings can cause AC interference.
What to do if a dot is flashing on the Lead Status screen of Welch Allyn CP 100 Medical Equipment?
If a dot is flashing on the Lead Status screen, lead-off information is displayed, or one or more leads prints as a square wave, it could be due to poor electrode contact or a loose lead. Try reattaching the lead, replacing the electrode, and ensuring the electrode area is properly prepared by shaving, cleaning with alcohol or acetone, and allowing it to dry. Also, make sure the electrodes have been stored and handled correctly.
