10. ANATOMY OF THE CHEST

11. Anatomy of the Chest
Chest cavity (thoracic cavity) makes up approximately half of torso.
Gets shape from 12 pairs of ribs.
Major organs contained within chest are heart and lungs.
Mediastinum houses trachea, esophagus, heart, vena cava, and aorta.
Teaching Tip: Use anatomical models, x-rays, and multimedia graphics to better illustrate anatomy and physiology of the chest.

12. The chest contains the heart and lungs and is separated from the abdominal cavity by the diaphragm muscle.

13. Anatomy of the Chest
Left and right sides of chest are occupied by the lungs.
Pleura: thin saclike structure that surrounds each lung.
Pleural space: potential space that exists between visceral and parietal pleura in chest.
Critical Thinking: Where does the chest end and the abdomen begin?

14. Each lung is surrounded by a thin lining of tissue called the pleura.
Class Activity: Divide class into groups. Provide one box of items to each group and direct students to create a lung model to demonstrate the mechanics of breathing. (A web search will produce a variety of sample plans to conduct this project.)
Box of items: Scissors, 3 Large balloons, 2 Rubber bands, Electrical tape, Plastic 2 liter bottle, Flexible plastic tubing - 8 inches, Y-shaped hose connector.
Each lung is surrounded by a thin lining of tissue called the pleura.

15. Think About It
What might happen if a chest injury disrupts the parietal pleura?
What might happen if a lung injury disrupts the visceral pleura?
What if there is a problem with the fluid that provides lubrication between the pleural layers?

16. CHEST INJURIES

17. Chest Injuries Closed Chest Injuries Open Chest Injuries
Result of blunt force trauma from falls, contact sports, vehicle collisions, blasts.
Open Chest Injuries
Result of penetrating injury from bullet, knife, or similar projectile.
Discussion Topic: Compare and contrast closed and open chest injuries.

18. An open chest injury.

19. Chest Injuries Blunt trauma Penetrating objects
Blow to chest can fracture ribs, sternum, and rib cartilages.
Penetrating objects
Bullets, knives, pieces of metal or glass, steel rods, pipes can penetrate chest wall, damaging internal organs and impairing respiration.
Talking Point: Although penetrating trauma can be more dramatic, do not underestimate the damage that can be done by blunt trauma.

20. Chest Injuries Compression
Results from severe blunt trauma in which chest is rapidly compressed (driver in motor-vehicle collision strikes chest on steering column).
Discussion Question: How else might organs of the chest be injured by blunt trauma?

21. Chest Injuries
Closed Chest Injuries: often caused by blunt force trauma to chest or back and are not associated with open wound.
Damage to ribs.
Pneumothorax: chest cavity filling with air from ruptured lung.
Hemothorax: blood from damaged soft-tissues and vessels enter chest cavity.
Discussion Question: How might rib fractures impair adequate breathing?
(continued)

22. Injured ribs can be splinted by securing bulky dressings tightly over the injured area.

23. Chest Injuries Closed Chest Injuries Flail chest Crepitus
Results when two or more ribs are broken in two or more places; can be life-threatening.
Crepitus
Grating sound when bones rub together.
Discussion Topic: Describe flail chest and paradoxical movement. Describe crepitus and/or provide audio example.

24. A flail segment results when two or more ribs are fractured in two or more places.

25. Chest Injuries Closed Chest Injuries: Signs-Symptoms Pain on breathing
Ecchymosis
Increased difficulty breathing
Accessory muscle use
Uneven chest wall movement during breathing
Signs and symptoms of shock
Talking Point: Uneven chest wall movement during breathing is a critical sign!

26. Chest Injuries Chest Injury Assessment
Perform primary assessment; ensure ABCs are intact.
Provide positive pressure ventilations, if breathing is inadequate.
Remove clothing over area where there is complaint of pain.
Observe and palpate for signs of deformity.
Discussion Topic: Discuss the treatment of a closed chest injury.
(continued)

27. Chest Injuries Chest Injury Assessment
Administer oxygen; follow local protocols.
Splint chest using bulky dressings or towels.
Place patient in a position of comfort, if no suspected spine injury.
Care for shock.
Transport patient.

28. Class Activity: Using manikins, direct students to work in pairs to take turns performing an assessment, palpating the chest for pain and deformity. Circulate around the room to provide guidance.
Use both hands to carefully and thoroughly palpate the chest for pain and deformity.

29. Chest Injuries Open chest injuries Sucking chest wound
Injury to chest that is associated with open wound.
Sucking chest wound
Open chest wound characterized by sucking sound each time patient inhales.
Tension pneumothorax
Air builds up inside chest cavity, causing excessive pressure on one side of chest.
Discussion Question: How might a hole in the chest disrupt the mechanics of breathing? How does this relate to pneumothorax?

30. A B
(A) Penetrating chest injuries can allow air and blood to enter the chest cavity. (B) A collapsed lung (spontaneous pneumothorax) can occur without outside trauma.

31. Chest Injuries Open Chest Wounds
Immediately seal with something that prevents air from entering wound, like gloved hand.
Take appropriate Standard Precautions.
Occlusive dressing: sterile gauze saturated with petroleum jelly.
Place occlusive dressing directly over wound and hold it in place.
Provide high-flow oxygen; care for shock.
Class Activity: Using a manikin, simulate an open chest wound. Direct students to demonstrate the proper application of an occlusive dressing.

32. Teaching Tip: Present examples of occlusive dressings
Teaching Tip: Present examples of occlusive dressings. Place an occlusive dressing over an open chest wound and tape in either three or four sides. Follow local protocol.

33. Chest Injuries Impaled Chest Wounds
Impaled objects must be stabilized and left in place.
Take appropriate Standard Precautions.
Perform primary assessment; ensure ABCs are intact.
Assist ventilations as appropriate.
Critical Thinking: Why is it important to never remove an impaled object?
(continued)

34. Chest Injuries Impaled Chest Wounds
Provide high-flow oxygen per local protocol.
Provide care for shock.
Initiate immediate transport.

35. Stabilize impaled objects using bulky dressings.

36. Think About It

What are your concerns?
How do you proceed?

37. ABDOMINAL EMERGENCIES

38. Abdominal Emergencies
Anatomy of the Abdomen and Pelvis
Diaphragm
Primary muscle of respiration; divides chest cavity from abdominal cavity.
Quadrant
Area of abdomen; used to identify location of pain during palpation.
Teaching Tip: Review the abdominal quadrants. Use landmarks to divide the abdomen and then discuss organ location within the quadrants.

(continued)

45. Abdominal Emergencies
Generalized Abdominal Pain
Diabetic emergencies
Kidney stones
Gallstones
Appendicitis
Ectopic pregnancy
Discussion Topic: Discuss the various medical causes for abdominal pain and how obtaining a thorough assessment in these cases is important.
(continued)

46. Abdominal Emergencies
Acute Abdominal Pain: Signs-Symptoms
Pain that is either sharp or dull
Pain on palpation
Rigid or tight abdomen
Bloating (distention)
Nausea/vomiting
Cramping
Pain that radiates to other areas
Guarding (protecting abdomen)
Critical Thinking: What medical problems might cause internal bleeding which would lead to abdominal pain?

47. Abdominal Emergencies
Acute Abdominal Pain: Assessment
Rule out history of trauma.
Injuries to abdomen can cause bleeding that is very slow.
Signs and symptoms can be delayed for hours, sometimes days.
Thorough medical history.
Talking Point: Emphasize that although thorough assessment is important, the primary goal is finding the life threat.

48. Think About It
You respond to the home of a 14-year-old female. Her mother reports that she dismissed her from school because of severe abdominal pain. She attempted to take the girl to the pediatrician, but the pain had intensified and she is unable to walk.
(continued)

49. Think About It
The patient has no other medical history, takes no medication, and has no allergies. She has a pulse of 100, blood pressure of 90/60, and respiratory rate of 24. You palpate the abdomen and find the patient guarding her RLQ, so you palpate that quadrant last (gently). She screams out in pain.
(continued)

50. Think About It What are your suspicions? How will you proceed?
What other questions should you be sure to include in your assessment of this patient?
Teaching Tip: Discuss referred tenderness (palpation of the left lower quadrant may produce tenderness and rebound tenderness in the right lower quadrant in appendicitis).

51. ABDOMINAL INJURIES

52. Abdominal Injuries
Abdominal injuries can produce life-threatening emergencies.
Signs and Symptoms
Deep cut or puncture wound to abdomen, pelvis, or lower back
Blunt trauma to abdomen or pelvis
Pain or cramps in abdominal or pelvic region
(continued)

53. Abdominal Injuries Signs and Symptoms Guarding
Lying still with legs drawn up
Rapid, shallow breathing; rapid pulse
Rigid, distended, and/or tender abdomen
Critical Thinking: A patient with abdominal pain will often find that lying with knees bent and feet flat on stretcher or lying lateral recumbent with knees bent is more comfortable than lying with legs extended. Why might that be?
Answer: It relieves abdominal musculature tension.

54. Abdominal Injuries Caring for Closed Abdominal Injury
Perform thorough assessment of abdomen; palpate all quadrants.
Expose abdomen to observe for signs of injury.
Allow patient to maintain position of comfort.
Discussion Question: What are the signs and symptoms of a closed abdominal injury? What are the potential life threats?

55. Abdominal Injuries

Never attempt to place spilled abdominal contents back into open wound.
Discussion Question: How will you manage the treatment of an abdominal evisceration?

56. Cut away clothing to expose the entire injury.

57. Place a large sterile dressing moistened with sterile water or saline over the exposed abdominal contents.

58. Place a plastic sheet over the dressing and secure in place.

59. An abdominal evisceration.
Class Activity: Using manikins or volunteers, simulate an evisceration with moulage. Read a realistic scenario and direct students to provide appropriate treatment.
An abdominal evisceration.

60. Think About It
You respond to a skateboard park where a 17-year-old boy has fallen onto concrete from a 20 foot height following a failed ramp jump attempt. He's complaining of persistent LUQ abdominal pain and nausea. His friends tell you he tried to get up but felt lightheaded.
(continued)

61. Think About It
Your patient is left lateral recumbent, guarding his abdomen, and moaning in pain. He has no other medical history, takes no medication, and is allergic to penicillin. His pulse is 100, blood pressure 100/70, and respirations are 28.
(continued)
