Patient ECG Hookup
Skin Preparation
Skin preparation is important to perform before electrode attachment to help ensure good signal quality when
transmitting patient data. Poor skin-electrode contact may cause noise or artifact which can affect the analysis of the
ECG data. Low amplitude signals may also be the result of poor skin-electrode contact.
To prepare the skin
1. Identify the electrode sites on the torso by referring to Positioning the Electrodes.
2. Remove any hair from the electrode sites using a razor.
3. Wipe oils from the electrode sites with an alcohol prep pad.
4. Remove any dead skin from the electrode sites with an abrasive pad. Two to three moderate rubs at each site
should be sufficient.
