Arterial Line

A very thin tube (catheter) is inserted into one of the patient's arteries (usually in the arm) to allow direct measurement of the blood pressure and to measure the concentration of oxygen and carbon dioxide in the blood. Arteries carry oxygen and nutrient-rich blood from the heart to tissues and organs throughout the body. Veins carry blood that is higher in waste products and carbon dioxide back to the heart and lungs. The arterial line allows nurses and doctors to monitor these levels at regular intervals. The arterial line is attached to a monitor. Click Here To Return To List

Brain Stem Evoked Response Equipment

Auditory brain stem responses evoked by stimulating the brain stem with painless sound waves using headphones. These sound waves are received by the brain, and a machine is used to test whether the brain stem has received the signals.

The quality of the brain stem's functioning in a comatose patient is thought to be an important indicator of the degree and location of brain injury. This highly specialized equipment is not available in all hospitals. Click Here To Return To List


A flexible plastic tube of varying sizes for withdrawing fluids from, or introducing fluids into, a cavity of the body. Frequently used to drain the urinary bladder. Click Here To Return To List

Central Venous (CVP) Line

A very thin tube which is inserted into a vein to measure the venous blood pressure (the pressure of the blood as it returns to the heart). CVP lines are inserted into veins in either the arm or the chest just below the shoulder, or occasionally on the side of the neck. The CVP line is connected to a monitor.

Chest Tubes

Tubes inserted into the chest between the lung and ribs to allow fluid and air to drain from the area surrounding the lungs. Removing this fluid and air from around the lungs allows them to more fully expand. An accumulation of fluid and air in the lung cavity can cause the lung to collapse. Chest tubes drain into a large plastic container near the foot of the patient's bed. The patient may have one or more of these tubes in place. Nurses will monitor the comatose patient for non-verbal signs of pain. Click Here To Return To List

Electrocardiogram (ECG/EKG)

The recording made by small, round electrode pads located on the patient's chest to monitor heart rate and rhythm. These are connected to a monitor and uses routinely in the intensive care unit. Click Here To Return To List

Endotracheal Tube (E.T. Tube)

A tube that serves as an artificial airway inserted through the patient's nose or mouth. It passes down the throat and into the air passages to help breathing. To do this, it must also pass through the vocal chords. 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.

Eye Tape

Tape used to close the patient's eyes. It is important that the eyes be kept moist. We do this naturally when we blink our eyes. This reflex is lost in the patient who is unresponsive but has open eyes. To protect the eyes and to prevent them from drying out, eye drops may be put into the eyes and eye tapes may be used to close them. Click Here To Return To List

Foley Catheter

This is a tube (catheter) inserted into the urinary bladder for drainage of urine. This helps to monitor the patient's fluid status and kidney function. The urine drains through the tube into a plastic bag hanging low by the foot of the bed. Click Here To Return To List

GI Tube

A tube inserted through a surgical opening into the stomach. It is used to introduce liquids, food, or medication into the stomach when the patient is unable to take these substances by mouth. Click Here To Return To List

Intracranial Pressure (ICP) Monitor

A monitoring device to determine the pressure within the brain. It consists of a small tube (catheter) attached to the patient's skull by either a ventriculostomy, subarachnoid bolt or screw and is then connected to a transducer, which registers the pressure.

Ventriculostomy is a procedure for measuring intracranial pressure by placing an ICP monitor within one of the fluid-filled, hollow chambers of the brain, called ventricles. These four natural cavities are filled with cerebrospinal fluid (CSF), which also surrounds the brain and spinal chord. Click Here To Return To List

Intravenous (IV) [ View Diagram]

Tubing inserted into a vein through which fluids and medications can be given. Click Here To Return To List

Intravenous Board

A simple wooden or plastic board usually attached with tape to the patient's forearm. It prevents bending and dislocation of the intravenous (IV), arterial or CVP lines. Click Here To Return To List

Jejunostomy Tube (J Tube)

A type of feeding tube surgically inserted into the small intestine. Click Here To Return To List

Leg Bag

A small, thick plastic bag that can be tied to the leg and collects urine. It is connected by tubing to a catheter inserted into the urinary bladder. Click Here To Return To List

Monitor, Intensive Care

A TV-like screen with a continuous display of different wave forms representing different pressures and activities in the body such as blood pressure, intracranial pressure, and EKG. It may also show a corresponding number for them (digital readout). Click Here To Return To List

Nasogastric Tube (NG Tube) [View Diagram]

A tube that passes through the patient's nose and throat and ends in the patient's stomach. This tube allows for direct "tube feeding" to maintain the nutritional status of the patient or removal of stomach acids. Click Here To Return To List

Posey Vest/Houdini Jacket

A vest worn to keep the patient stationary. This is for the patient's safety. Click Here To Return To List


A machine that does the breathing work for the unresponsive patient. It serves to deliver air in the appropriate percentage of oxygen and at the appropriate rate. The air is also humidified by the respirator. Click Here To Return To List


A procedure to draw off excessive fluid in the brain. A surgically-placed tube running from the ventricles which deposits fluids into either the abdominal cavity, heart or large veins of the neck. Click Here To Return To List

"Space Boots" (Spenco Boots)

Padded support devices made of lamb's wool used to position the feet and ankles of the patient. Without this support and alignment, patients who are unconscious for long periods may develop deformities limiting future movement. Click Here To Return To List

Subarachnoid Screw

Also Subarachnoid Bolt. A device for measuring intracranial pressure which is screwed through a hole in the skull and rests on the surface of the brain. Click Here To Return To List

Support Hose/TEDS

Anti-embolic stockings. Tight knee or thigh-high stockings that support the leg muscles and thus help prevent pooling of blood in veins of legs. Click Here To Return To List

Swan-Ganz Monitor

A catheter (tube) similar to the Central Venous Pressure (CVP) Line. It is used to measure blood pressure and blood gas concentrations in the right side of the heart, in vessels of the lungs and in the left side of the heart. Click Here To Return To List

Tracheostomy Tube

A tube inserted into a temporary surgical opening at the front of the throat providing access to the trachea and windpipe to assist in breathing. Click Here To Return To List


A weighted traction setup composed of pulleys and lines used in the care of the patient with broken leg or spine. After repair of the fractures and application of the appropriate casts, weights are used to keep the bones in alignment. Click Here To Return To List


A sensitive electronic device which detects bodily functions, such as heart rate and blood pressure, and transmits signals representing those functions to a monitor so that the can be observed. Click Here To Return To List
