10.4.3 Reusable Electrodes
Follow the below guidelines to maintain the reusable electrodes:
 Clean the electrodes after each use and make sure there is no
remainder gel on them.
 Keep the rubber bulbs of chest electrodes away from direct
sunshine and excessive temperature.
 After long-term use, the surfaces of electrodes will be oxidized
because of erosion and other causes. At this time, electrodes
should be replaced to achieve high-quality ECG records.
 For the replacement cycle of the electrodes, refer to their
instructions for use.
10.4.4 Recording Paper
Follow the below guidelines to store the thermal recording paper:
 Recording paper should be stored in dry, dark and cool area,
avoiding excessive temperature, humidity and sunshine.
 Do not put the paper under fluorescence for a long time.
 Be sure that there is no polyvinyl chloride or other chemicals in
the storage environment, which will lead to color change of the
paper.
 Do not stack up the recording paper for a long time, or else the
ECG record may trans-print each other.
