2.  Lungs  Mediastinum Heart Aorta and great vessels Esophagus Trachea

3.  Diaphragm contracts  Moves down  Increasing the volume of the thoracic cavity  When the volume increases, the pressure inside ________.  Pressure within the lungs is called intrapulmonary pressure

4.  Phrenic nerve stimulus stops  Diaphragm relaxes  This ______ the volume of the thoracic cavity  Lung volume decreases, intrapulmonary pressure _____

5. If two areas of different pressure communicate, gas will move from the area of higher pressure to the area of lower pressure

6. Parietal pleura lines the chest wall Visceral pleura (pulmonary) covers the lung

7. Parietal pleura Visceral pleura Normal Pleural Fluid Quantity: Approx. 20 - 25mL per lung Lung RibsIntercostal muscles

8.  Area between pleura ----“potential space”  Normally, negative pressure between pleura

15.  Diagnostic tests  Client position  Treatment depends on severity Chest tube Heimlich valve on chest tube

16.  Also called “thoracic catheters”  Different sizes From infants to adults Small for air, larger for fluid  Different configurations Curved or straight  Types of plastic PVC Silicone  Coated/Non-Coated Heparin Decrease friction

17.  In what setting/environment is a chest tube placed?

20.  Sterile Tech  Small incision  Tube is sutured  Dressing applied

24. Chest tube is attached to a drainage device Allows air and fluid to leave the chest Contains a one-way valve to prevent air & fluid returning to the chest Designed so that the device is below the level of the chest tube for gravity drainage

25. 1. Remove fluid & air as promptly as possible 2. Prevent drained air & fluid from returning to the pleural space 3. Restore negative pressure in the pleural space to re-expand the lung

26.  Dressing changes  No dependent loops  Oxygen therapy  Record output  Analgesics  IS and turn, cough, deep breathe

27.  Health history-respiratory disease, injury, smoking, progression of symptoms  Physical exam- degree of apparent resp distress, lung sounds, O2 sat, VS, LOC, neck vein distention, position of trachea  All require observation for respiratory symptoms  Pertinent nursing problems Acute pain Ineffective airway clearance Impaired gas exchange Home care

28. How a chest drainage system works

29. Tube open to atmosphere vents air Tube from patient

30.  For drainage, a second bottle was added  The first bottle collects the drainage  The second bottle is the water seal  With an extra bottle for drainage, the water seal will then remain at 2cm

31. The depth of the water in the suction bottle determines the amount of negative pressure that can be transmitted to the chest, NOT the reading on the vacuum regulator

32.  Expiratory positive pressure  Gravity  Suction

35.  Chamber A Suction control chamber  Chamber B Water seal chamber  Chamber C Air leak monitor  Chamber D Collection chamber Be sure you under stand how to set up the system, the function of each chamber and how to troubleshoot issues with each chamber.

36. Monitoring  Water seal is a window into the pleural space  Not only for pressure  If air is leaving the chest through an air leak, bubbling will be seen here  Air meter (1-5) provides a way to “measure” the air leaving and monitor over time – getting better or worse?

37.  Focused respiratory assessment Breath sounds Respiratory rate Respiratory depth SpO2 ABG CXR

38.  Cardiovascular assessment  Level of consciousness  Pain  Chest tube

39.  System position  Tubing position  Connections to patient and system  Assessing the system  Monitoring output

40. What are some common complications?

41.  Chest tube malposition (most common)  Subcutaneous emphysema  High Fluid in Water Seal Chamber Chest system may need to be vented  Air leak Others pleural effusion, inc. pneumo, pulmonary edema mediastinal shift ?

43.  Check fluid level in suction chamber  Observe water seal chamber fluid level  Assess for tidaling in water seal chamber  Assess for tubing – non dependent  Determine if the unit has been knocked over  Note the amount, color and consistency of drainage

44.  Monitor your client  Notify MD STAT if Significant drainage Increasing shortness of breath Pain Absence of breath sounds

45.  Do not remove suction without an order  Manage pain  When full - place in biohazard container  Do not change collection device on client with an air leak without an order  When suction discontinued, must disconnect from suction, not just turn off

46.  What is the progression of events for discontinuing a chest tube?  Can a patient ambulate with a chest tube?
