CHEST TUBE DRAINAGE SYSTEM

Description

• The chest tube drainage system returns negative pressure to the intrapleural space.
• The system is used to remove abnormal accumulations of air and fluids from the pleural space

Drainage collection chamber

• The drainage collection chamber is located where the chest tube from the client connects to the system.
• Drainage from the tube drains into and collects in a series of calibrated columns in this chamber.

Water seal chamber:

• The tip of the tube is underwater, allowing fluid and air to drain from the pleural space and preventing air from entering the pleural space.
• Water oscillates (moves up as the client inhales and moves down as the client exhales).
