Chest Tubes Flashcards

1
Q

Where are chest tubes placed?

A

Chest tubes are placed in the pleural space for the purpose of draining air or fluid and relieve resp distress
-comfort, perfusion and ventilation

Q

Who inserts the chest tube?

A

Placed by physician

Catheter is placed through chest wall into intrapleural space

Q

What does negative pressure do?

A

Allows air to enter but not escape
Pleural fluid keeps alveoli from collapsing
Allows lungs to expand

Q

What keeps lungs from collapsing?

A

Residual volume of air that keeps small airways always open
The surface tension of the serous fluid between the pleura together with the pressure induced by pulling action of the diaphragm

Q

Where is tubes placed that are used for air only?

A

Placement is usually the anterior cheat on the mid clavicular line at the 2nd and 3rd intercostal space

Located here because air rises to the highest point in the chest

Patient should be in semi to high fowler

Q

Tube location for blood, puss or effusion?

A

Usually placed lower in the chest on the mid axillary line of the 4th or 5th intercostal space

Patient should be in high fowler to facilitate gravity draining

Q

Pneumothorax?

A

Air enters chest cavity causing loss of negative pressure
Limits lung expansion

Causes: blunt trauma, spontaneous in young males

S&S: sharp pleuritic chest pain, decreased breath sounds, SOB

Q

Pleural effusion?

A

Non bloody fluid in the pleural space
Fluid takes up space in thoracic cavity resulting in decreased lung volumes

Cause: disease or inflammation

S&S: dull, achieve chest, decreased breath sounds, cough, dyspnea

Q

Water seal chamber?

A

Used to provide funnel to fill the water seal chamber with 2cm of sterile water

It allows air to exit from the pleural space on exhalation and prevents air from entering back into chest on inhalation

Q

Patient air leak meter?

A

Indicates the approximate degree of air leak from the chest cavity
-the higher the number the greater degree of air leak

Bottom left window

20
Q

Positive pressure relief valve?

A

Opens with increase in positive pressure, preventing pressure accumulation

do not obstruct positive pressure valve

Top left valve

21
Q

High negatively float valve and relief chamber?

A

Preserves the water seal in the presence of high negativity. Used to reduce negativity.

Action:

  • water floats the valve up into the closed position when excessive negativity occurs
  • valve opens upon decrease in negativity

Connected to air leak meter

22
Q

High negative relief valve?

A

Used to vent excessive negativity

Depress button to relive negativity
Causes filtered air to enter the unit and the water level in the water seal will drop
Release button when desired level of level of negativity is reached

Top right valve

23
Q

Collection chamber?

A

Used to collect drainage

Fluids overflow from one section to the next
Total capacity is 2500cc

Located on tubes on right

24
Q

Routine assessment for chest tubes?

A 
ABCs
Resp distress
Chest pain
Breath sounds over affected lung
VS 
Correct position 
Palpation: subcu emphysema 
Unit in upright position and below level of insertion 
Environment 
Dressing 
Tubing free from kinks and clots 
Listen for leaks 
Fluid check (2cm) 
Amount and type of drainage 
Suction
25
Q

What’s it called when water moves up and down the water seal chamber?

A

Tidaling

26
Q

What can occur with a chest tube?

A

Atelectasis

27
Q

What position should the patient be in when they have a chest tube?

A

Semi or high fowlers

Semi: to evacuate air

High: to drain fluid

28
Q

What can LPNs do with chest tubes?

A

LPNs can check and maintain chest tube equipment
Assist with set up and dressing changes
Monitor and asses
Report to RN and physician

29
Q

How frequent should assessments be done?

A

Every 4 hours unless pt condition changes

30
Q

What should always be in reach of chest tube?

A

2 clamps

  • no teeth
  • RN only

Clamping creates closed system

31
Q

When to use a clamp?

A

Changing unit
W/ physician order
Following instillation
Assessing for air leak

32
Q

Chest tube dressings?

A

Requires cleaning and monitoring
Change as per order q2days and PRN
Do not use waterproof tape on skin at insertion site

33
Q

What happens if chest tube is pulled out?

A

Cover with gauze
Tape only 3 sides
Call doctor

Potential of entry of microorganisms

34
Q

What to do if there’s pooling of secretions?

A

Need to change tension and proper positioning of tubing

Potential for pathogen build up

35
Q

How to decrease risk of patient pulling out tube?

A

Have tubing where they can see it so they don’t accidentally dislodge or roll over on it

36
Q

Assessment at insertion site?

A

Discharge
Redness
Shadowing
Dampness

Signs of infection*

37
Q

What to check if someone is experiencing SOB with chest tube?

A

Assess breath sounds
Is tubing secure?
Is tubing kinked, obstructed?
Is the clamp open?

38
Q

Bubbling in air leak meter?

A

Check and tighten connections
Test tubing for leaks
Check insertion site for obvious leaks?

39
Q

One way valve?

A

Let’s air and fluid pass in one direction only

Ex. Heimlich flutter valve

Used for simple pneumothorax

40
Q

Potential complications of chest tube?

A

Air leak
Severe resp distress or chest pain
Absence of breath sounds of affected side
Dependent loops of drainage trapped
Absence of fluctuation with respirations
Chest tube dislodged
Bleeding

41
Q

What to do if patient shows resp distress or chest pain?

A

Stay with patient
Call bell for RN or physician
Is drainage system in right position?

42
Q

What do you do if there’s absence of breath sounds?

A

Code blue

43
Q

What to do if there’s dependant loops with fluid trapped?

A

Drain into drain bottle
Reposition tubing
Patient teaching

44
Q

Valsalva maneuver?

A

the action of attempting to exhale with the nostrils and mouth, or the glottis, closed.

45
Q

What time of pressure is maintained during expiration?

A

Negative pressure
