Signs and Symptoms• Pain at site of injury
• Pain aggravated by increased breathing
• Bruising to chest wall
• Crepitus with palpation of chest
• Penetrating injury to chest
• Dyspnea
• Hemoptysis
• Failure of chest to expand normally
• Rapid, weak pulse and low blood pressure
• Cyanosis around lips or fingernails

Inspection
• Decreased breath sounds usually indicate significant damage to a lung.
• If both sides of chest do not have equal rise and fall, chest muscles have lost ability to work properly.
• If one section of chest moves in opposite direction from the rest of the chest (paradoxical motion), this is a life threat.

Immediate Interventions• Decide SICK/NOT SICK.• Provide complete spinal immobilization.• Apply an occlusive dressing to any
penetrating chest injury.• Stabilize paradoxical motion with a large
bulky dressing and 2'' tape.• Apply oxygen via non-rebreathing mask.• Provide positive pressure ventilations if
breathing is inadequate.• Control bleeding/treat for shock.

Circulation• Assess patient’s pulse.• Consider aggressive treatment for shock.• Internal bleeding can quickly cause death.• Pay attention to subtle clues such as:
– Skin signs– Level of consciousness– Sense of impending doom

Complications of Chest Injuries
3
A pneumothorax occurs when air leaks into the space between the pleural surfaces.
A pneumothorax occurs when air leaks into the space between the pleural surfaces.
![Page 60: Seattle/King County EMT-B Class. Topics 123 Eye Injuries: Chapter 25 Face & Throat Injuries: Chapter 26 Chest Injuries: Chapter 27](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649cfd5503460f949cde25/html5/thumbnails/60.jpg)
Pneumothorax• Air enters through a
hole in the chest wall.– The lung may
collapse in a few seconds or a few minutes.
• An open or penetrating wound to the chest is called a sucking chest wound.
3
![Page 61: Seattle/King County EMT-B Class. Topics 123 Eye Injuries: Chapter 25 Face & Throat Injuries: Chapter 26 Chest Injuries: Chapter 27](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649cfd5503460f949cde25/html5/thumbnails/61.jpg)
Care for Open Pneumothorax• Clear and manage
the airway.• Provide oxygen.• Seal an open
wound with an occlusive dressing.
• Depending on local protocol, tape down all four sides or create a flutter valve.

![Page 62: Seattle/King County EMT-B Class. Topics 123 Eye Injuries: Chapter 25 Face & Throat Injuries: Chapter 26 Chest Injuries: Chapter 27](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649cfd5503460f949cde25/html5/thumbnails/62.jpg)
Spontaneous Pneumothorax• Some people are born with or develop
weak areas on the surface of the lungs.• Occasionally, the area will rupture
spontaneously, allowing air into the pleural space.
• Patient experiences sudden chest pain and trouble breathing.
• Consider a spontaneous pneumothorax for a patient with chest pain without cause.

Tension PneumothoraxCan occur:
• from sealing all four sides of the dressing on a sucking chest wound.
• from a fractured rib (closed injury) puncturing the lung or bronchus.
• as a result from a spontaneous pneumothorax.

Care for Tension Pneumothorax• If a tension pneumothorax
develops from sealing an open chest wound, partly remove the dressing to let the air escape.
• If there is no open wound, follow local protocol.

![Page 67: Seattle/King County EMT-B Class. Topics 123 Eye Injuries: Chapter 25 Face & Throat Injuries: Chapter 26 Chest Injuries: Chapter 27](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649cfd5503460f949cde25/html5/thumbnails/67.jpg)
Hemothorax• Collection of blood in the pleural space• Suspect if the following are seen:
– Signs and symptoms of shock– Decreased breath sounds on affected
side
• If both air and blood are present in the pleural space, it is a hemopneumothorax.

Rib Fractures• They are very common in the older
people.• A fractured rib may lacerate the surface
of the lung.• Patients will avoid taking deep breaths
and breathing will be rapid and shallow.• The patient often holds the affected side
to minimize discomfort.• Administer oxygen.

![Page 70: Seattle/King County EMT-B Class. Topics 123 Eye Injuries: Chapter 25 Face & Throat Injuries: Chapter 26 Chest Injuries: Chapter 27](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649cfd5503460f949cde25/html5/thumbnails/70.jpg)
Flail Chest
• Segment of chest wall detached from rest of thoracic cage
• Occurs when:– Three or more ribs are fractured
in two or more places.– Sternum is fractured along with
several ribs.• Creates paradoxical motion
(asymmetrical and opposite movement of the chest during inspiration/expiration)

Care for Flail Chest• Maintain airway.• Provide respiratory
support with BVM if needed.
• Perform ongoing assessments for pneumothorax and other respiratory complications.
• Immobilize flail segment.

![Page 73: Seattle/King County EMT-B Class. Topics 123 Eye Injuries: Chapter 25 Face & Throat Injuries: Chapter 26 Chest Injuries: Chapter 27](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649cfd5503460f949cde25/html5/thumbnails/73.jpg)
Pulmonary Contusions
• Bruising of the lung.• Develops over hours.• Alveoli fill with blood, and edema
accumulates in the lung, causing hypoxia.
• Provide oxygen and ventilatory support.
3
![Page 74: Seattle/King County EMT-B Class. Topics 123 Eye Injuries: Chapter 25 Face & Throat Injuries: Chapter 26 Chest Injuries: Chapter 27](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649cfd5503460f949cde25/html5/thumbnails/74.jpg)
Traumatic Asphyxia• Sudden, severe compression of chest,
i.e.: (crushed by a car that fell of the jack)
• Produces rapid increase in pressure within chest
• Results in neck vein distention, cyanosis, and bleeding into the eyes
• Provide supplemental oxygen and monitor vital signs.
• Transport immediately.

![Page 75: Seattle/King County EMT-B Class. Topics 123 Eye Injuries: Chapter 25 Face & Throat Injuries: Chapter 26 Chest Injuries: Chapter 27](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649cfd5503460f949cde25/html5/thumbnails/75.jpg)
Blunt Myocardial Injury• Bruising of heart muscle.• Pulse is often irregular.• There is no prehospital treatment
for this condition.• Check patient’s pulse and note
irregularities.• Provide supplemental oxygen and
transport immediately.

Pericardial Tamponade• Blood or other fluids collect in the pericardium.

![Page 77: Seattle/King County EMT-B Class. Topics 123 Eye Injuries: Chapter 25 Face & Throat Injuries: Chapter 26 Chest Injuries: Chapter 27](https://reader030.vdocuments.us/reader030/viewer/2022032703/56649cfd5503460f949cde25/html5/thumbnails/77.jpg)
Pericardial Tamponade, cont'dSigns and symptoms include:
• Very soft and faint heart tones• Weak pulse• Low blood pressure• Decrease in difference between
systolic and diastolic blood pressure• Jugular vein distention (JVD)
Provide oxygen and transport quickly.

Laceration of the Great Vessels• The superior vena cava, inferior vena
cava, pulmonary arteries and veins, and aorta are contained in the chest.
• Injury to these vessels can cause fatal hemorrhage.
• Treatment includes:• Ventilatory support• Supplemental oxygen• CPR• Transport immediately.
