UWSD Flashcards
What is the purpose of a chest tube ?
A tube inserted into the pleural space to remove air/fluid and help lung re-expand
OR
Tube inserted in mediastinum space to drain fluid from around the heart after cardiac surgery
What are the reasons for a chest tube ?
-pneumothorax (air enters pleural space)
-pleural effusion (fluid in pleural space)
- haemothorax (blood enters pleural space)
-empyema (infection in pleural space)
-chylothorax(lymphatic fluid in pleural space)
- cardiac surgery
What are the different types of chest tube drainage ?
- wet suction
- dry suction
What is the nurses role w chest tubes
- keep drainage sys below pts chest
-keep tubing free from kinks + that it drains freely + connections are sealed
-monitor drainage collection chamber : drainage colour + amount + record reg
-monitor water seal drainage 2 see if water lvl fluctuating
-H2O in water chamber can evaporate so make sure to refill reg @ prescribed amount 4 suction
-monitor air leak monitor 4 excessive bubbling (not good)
-check suction pressure
How does the water seal chamber work ?
Performs underwater seal to allow air to be removed from pleural space while preventing outside air from entering lungs (creates neg pressure)
- water will fluctuate as pt breathes in and out
- water will increase during inspiration +decrease during expiration (opposite if pt on positive pressure device )
What does it mean if the water in the water seal chamber is not fluctuating at all?
- lung may have re-expanded (prob corrected
- there is a kink somewhere
What are we looking for in the air leak monitoring area ?
- excessive bubbling as it could mean air leak
- if pt has pneumothorax there could be intermittent bubbling
What is the assessment nd mgt 4 pts w a chest tube ?
Monitor pts :
-lung sounds
-resp rate nd effort
-4 dysopnea
-SpO2 readings
- insertion site - free 4rm infection
- sub-cut crepitus ( CO2 escaping into tissues - will feel puffy + like crackling sensation under d skin)
Encourage pt 2 cough + deep breathing - moves fluid and helps lung function
Reposition pt reg
Check drainage tubing
Check CDU (collection chamber, water seal chamber, suction Chamber)
What should you do if a pts chest tube becomes dislodged?
-cover site w sterile dress + tape on 3 sides + notify doc
What should you do if the system breaks ?
Insert tubing 1-inch into bottle of sterile water + get new drainage system
What is the protocol for clamping the tube ?
Follow hospital policy as clamping ^ risk of tension pneumothorax
Never clamp w/o doctors order
What are the functions of a chest tube
-drain fluid and/or air from chest
-prevent air from entering chest and creating a pneumothorax
-control the lvl of suction (if being used ) to facilitate re-expansion of the lung
What are the chambers that chest drainage units consist of ?
- Chamber that collects the chest drainage
- Chamber that prevents air from entering the chest
- Chamber that controls suction
What are the times where the suction chamber is used ?
- to assist removal of thick drainage,bloody drainage or large amounts of drainage
What is the difference between a wet suction unit and dry suction unit ?
Wet suction- uses chamber filled w water to control lvl of suction
Dry suction- uses mechanical suction control rather than a water sealed chamber (more popular choice)
