Edema
Collection of fluid in the tissue causing swelling.
Electroencephalogram (EEG)
A procedure that uses electrodes on the scalp to record electrical activity of the brain. Used for detection of epilepsy, coma, and brain death.
Electromyography (EMG)
An insertion of needle electrodes into muscles to study the electrical activity of muscle and nerve fibers. It may be somewhat painful to the patient. Helps diagnose damage to nerves or muscles.
Emotional Lability
Exhibiting rapid and drastic changes in emotional state (laughing, crying, anger) inappropriately without apparent reason.
Endotracheal Tube
A tube that serves as an artificial airway and is inserted through the patient's mouth or nose. It passes through the throat and into the air passages to help breathing. To do this it must also pass through the patient's vocal cords. The patient will be unable to speak as long as the endotracheal tube is in place. It is this tube that connects the respirator to the patient.
Evoked Potential
Registration of the electrical responses of active brain cells as detected by electrodes placed on the surface of the head at various places. The evoked potential, unlike the waves on an EEG, is elicited by a specific stimulus applied to the visual, auditory or other sensory receptors of the body. Evoked potentials are used to diagnose a wide variety of central nervous system disorders.
Extended Care Facility-Basic
Residential facility which supplies 24-hour nursing care and supervision and assistance with activities of daily life. See Program/Service Types.
Extended Care Facility-Skilled
A residential facility for the patient who requires 24-hour nursing care (IV, intramuscular injections, special feeding tubes, skin care, oxygen) and rehabilitative therapy, such as physical therapy, occupational therapy, or speech therapy on a less intensive basis than as an inpatient in a comprehensive rehabilitation center. An extended care facility can be a short-term alternative (a few months) prior to placement at home (with outpatient therapy) or in a nursing home. See Program/Service Types.
Extremity
Arm or leg.
