Electroencephalography (EEG) equipment is used for measuring brain activity, and different types of this equipment perform various functions. EEG brainwave diagnostic testing devices are used to diagnose certain malfunctions or disorders within the brain. Ambulatory EEG equipment may be used by emergency medical technicians (EMTs) while transporting patients to the hospital. EEG analysis software is a type of EEG equipment necessary for printouts and digital readings. Clinical studies involving brain function often involve the use of neurofeedback and biofeedback machines.
An EEG monitor is necessary to view brain activity during testing. These are often used in conjunction with sensors and cables. During diagnostic testing or feedback, a sensor may be placed on the patient's forehead, then attached to a cable. The cable is connected to the EEG monitor. The EEG equipment enables technicians or physicians to view brain activity.
One computer-based type of EEG device is known as the polysomnography machine. This equipment may work with a video camera. The polysomnography device records brain activity when connected to a person's forehead or scalp. Another type of EEG equipment is known as a peripheral nerve stimulator. These machines often use electrodes to stimulate damaged nerves. These are typically made with an LCD window and may be battery powered or operate on electrical current.
Amplifiers are accessories that are used with various types of EEG machines. Amplifier holders are EEG equipment accessories as well. These are also made for use in ambulances.
EEG equipment such as electromyograph machines often require the use of a neurotrac printer. These special printers provide readouts of brain activity generally printed on thermal paper. These devices are typically portable and often weigh less than 25 pounds (11.36 kilograms).
There are also EEG devices used for monitoring home care patients. One such device is a hand-held modular ambulatory EEG. These can typically record activity for up to 48 hours. They are very lightweight and may be kept in a pouch for easy storage.
Eye tracking devices are another type of EEG equipment. This equipment may be mounted on the head to track eye movements in a patient. A long-range optics module will enable the technician or physician to obtain a clear view of the structure of the patient's eye. Redirection mirrors and filters are often used with this type of device.
Wireless devices are also used for EEG testing. This type of equipment will capture EEG activity in real time and the devices are also hand held. These radios generally can monitor electrical activity within the brain.
