ECG gel, also known as electrocardiogram gel or EKG gel, is a conductive medium used in electrocardiography (ECG) procedures to improve the quality of electrical signal transmission between the skin and the electrodes of the ECG machine. Here's more information about ECG gel: Purpose: The primary purpose of ECG gel is to enhance the conductivity and reduce impedance between the skin and the ECG electrodes. This improves the quality and accuracy of the electrical signals detected by the electrodes, resulting in clearer and more reliable ECG readings. Composition: ECG gel is typically a water-based, conductive gel formulated to be non-greasy, non-staining, and hypoallergenic. It may contain ingredients such as water, glycerin, propylene glycol, carbomer, preservatives, and conductivity-enhancing agents. Conductivity: ECG gel is formulated to have high electrical conductivity, allowing it to effectively transmit electrical signals between the skin and the electrodes. This conductivity helps minimize impedance and artifacts, ensuring accurate ECG readings even in challenging conditions. Viscosity: ECG gel is usually designed to have a suitable viscosity that allows for easy application and smooth spreading on the skin. It should be thick enough to stay in place during the procedure but not so thick that it hinders electrode placement or skin contact. Compatibility: ECG gel is compatible with various types of ECG electrodes, including disposable electrodes, reusable electrodes, and adhesive electrodes. It can be used with both standard ECG procedures and specialized cardiac tests such as stress tests, Holter monitoring, and echocardiography. Application: ECG gel is applied directly to the skin at the electrode sites before attaching the electrodes. A sufficient amount of gel should be applied to ensure good contact between the electrodes and the skin surface. Excess gel can be wiped away after electrode placement. Hygiene: ECG gel should be stored in a clean and dry environment to prevent contamination. Disposable single-use packets or bottles with dispensing caps are commonly used to maintain hygiene and prevent cross-contamination between patients. Removal: After the ECG procedure, any remaining gel should be wiped off the skin using a clean, dry cloth or disposable wipe. Residual gel left on the skin can cause discomfort or irritation if not properly removed.
