Cardiopulmonary Devices and Central Venous Lines Vocabulary

Vocabulary flashcards covering ventilators, chest tubes, endotracheal tubes, central venous catheters, and cardiac output parameters from the lecture material.

Mechanical Ventilators

Devices connected to an artificial airway inserted into the trachea when the cardiopulmonary system cannot adequately supply oxygen to the tissues.

Thoracostomy Tube (Chest Tube)

A tube used to drain the intrapleural space and the mediastinum, and to reestablish negative intrapleural pressure in cases of a pneumothorax, hemothorax, pleural effusion, and empyema.

Endotracheal Tubes

Tubes placed into the trachea usually through the mouth or nose, or sometimes through a tracheostomy, whose proper positioning is verified by chest radiography with the tip 1-2" above the carina.

Central Venous Lines

Catheters inserted into a large central vein (preferably the SVC due to its size) for administration of drugs, transfusions, and to monitor cardiac pressures.

Totally Implanted Access Ports

Central access devices implanted under the skin, which include Infusa port, Port-a-cath, and Mediport.

PICCs

Peripherally inserted catheters used as central venous lines.

Externally Tunneled Catheters

Central venous lines that pass under the skin, including Broviac, Hickman, and Groshong catheters.

Swan-Ganz Catheters

Central venous lines that incorporate a small electrode at the distal end used to monitor heart blood flow and pressures.

Electrocardiogram

A cardiac trace device named after 'Kardia', the Greek word for heart; EKG and ECG are used synonymously.

Cardiac Output

The product of heart rate and stroke volume, which requires adequate blood volume and a regular cycle of muscular contraction and relaxation.
