What is an electroencephalograph (EEG) machine?
An EEG machine is a device that measures the electrical activity in the brain. The electrical signals that come from the brain can help the doctor identify what is wrong with the brain. However, the EEG machine only measures electrical activity in the brain. There is much about brain function that cannot be measured by the EEG. The EEG machine may either be a separate piece of equipment or available in the bedside monitor. The EEG machine obtains its measurements through wires, called leads, connected to sensors (EEG pads) placed on a patient's head.
When is an EEG machine used?
An EEG machine is used when the doctor wants to monitor the electrical activity in the brain. This machine is used when the doctor wants to see if the brain is functioning normally and to monitor therapies that affect the brain.
