During an ECG procedure, what should the gel on each electrode be?

The gel on each electrode should be moist and fresh to ensure optimal conduction of electrical signals from the heart to the ECG machine. Properly hydrated gel enhances the electrical contact between the skin and the electrode, reducing impedance and improving the quality of the ECG tracing. This is vital for an accurate assessment of the heart's electrical activity, aiding in the diagnosis of potential dysrhythmias and other cardiac conditions.

Using fresh gel ensures that it is effective in adhering to the skin and conducting electrical signals. Moisture helps decrease skin resistance, which can otherwise distort the ECG readings. Conversely, using dry, old, or improperly prepared gel could lead to poor signal quality and inaccurate results, making it difficult to diagnose any potential issues correctly. Therefore, maintaining the gel in a moist and fresh state is crucial for successful ECG monitoring and interpretation.
