Electrodes are important sensors for medical exams such as ECGs. They allow sensors to stick to a patient’s skin and pick up on valuable readings, giving medical professionals an accurate view of a patient’s health. There are many different types of electrodes, including foam electrodes. Here are a few reasons why these electrodes are used in medicine and why they are so popular in the medical world.
Foam Electrodes Adhere Better
These types of electrodes use a special type of adhesive called adhesive hydrogels that have a much better track record of sticking to the skin. This is particularly valuable for tests that require a lot of movement, such as stress tests and halter tests. You don’t want to have to worry about the electrode slipping out of place and damaging the reading because it’s able to stick to the skin properly.
They Have a Barrier Against Fluids
Electrodes are valuable in gathering readings about a patient’s heart functioning and other problems, but anything that disturbs the sensors can make the results unreadable, especially fluids. Luckily, foam electrodes are fluid-resistant, which means that liquids cannot get into the sensor itself. You may wonder why electrodes need to fend off fluids, but even a patient’s sweat can affect the accuracy of reading, so a resistant electrode is important.
They Yield Accurate Readings
Thanks to these properties, electrodes made out of foam yield some of the most accurate readings. Even a small difference can mean vital early detection of a health problem, so accuracy is very important.
