ECG Electrodes - available at stock
The choice of electrode shape depends on several factors, including the type of monitoring or procedure, the type of gel being used, and personal preference in shape and backing material.
Monitoring electrodes with wet gel (liquid gel) are electrodes filled with a wet gel to allow better electrical conductivity and reduce the risk of electrical interference. This type of electrode is commonly used in cardiac monitoring and ECG recordings to ensure accurate recording of cardiac rhythm. Wet gel electrodes should be protected from moisture to prevent damage to the gel or the electrode itself, and stored in a cool place to prevent the growth of microorganisms.
Solid gel electrodes are suitable when rapid application is required and moisture is not needed to allow good electrical conductivity. This type of electrode can be applied directly to the skin and requires no preparation. They are often appropriate in short-term monitoring applications, such as emergencies or clinical examinations that do not require prolonged monitoring. In addition, they are convenient for mobile use and easy to deploy when needed.
However, round electrodes can be advantageous in certain applications because they are easier to apply and provide a larger contact area, which can result in better signal quality. Ultimately, it is important to choose the right electrode shape for the specific application, taking into account the manufacturer's recommendations and the experience and expertise of the medical staff.
The choice between nonwoven, fabric, or foam as the backing material for electrodes differs as follows: Nonwoven electrodes are soft and have good adhesion, which makes them advantageous for long-term monitoring or procedures that require a long electrode life. Fabric electrodes have a good skin contact area and high breathability, which makes them beneficial for monitoring in high physical stress or monitoring in high skin moisture. And foam electrodes are soft and comfortabe, havan excellentod fit , but can cause skin irritation if necessary.
