Chapter 30: Lower Respiratory Problems
Overview
Focus on chest trauma and thoracic injuries
Page 2: Chest Trauma and Thoracic Injuries
Recognition of the impact of traumatic injuries on respiratory system and mortality.
Page 3: Traumatic Chest Injuries
Traumatic injuries range from simple rib fractures to cardiorespiratory arrest.
Classify injuries into:
Blunt Trauma: No object penetrates the body, resulting from strikes or impacts.
Penetrating Trauma: Involves foreign objects penetrating body tissues.
Page 4: Mechanisms of Injury
Blunt Trauma
Caused by external forces striking or impacting the chest.
Can cause shearing, and compression injuries of structures beneath the chest wall.
Symptoms may appear minor externally but lead to severe internal damage.
Penetrating Trauma
Involves an object impaling or passing through the body, creating wounds.
Page 5: Fractured Ribs
Characteristics
Most commonly affect ribs 5 through 9, which are least protected. (could stab an organ)
Potential damage to pleura, lungs, heart, and other organs.
Manifestations
Symptoms include:
Pain upon inspiration and coughing
Splinting (restrictive breathing)
Shallow respirations
guarding
Page 6: Complications and Treatment for Rib Fractures
Complications
Potential for atelectasis and pneumonia.
Avoid tape or thoracic binders. DO NOT!
Treatment Approaches
Pain management using NSAIDs, opioids, nerve blocks.
Patient education on:
Deep breathing and coughing exercises
Use of incentive spirometry
Analgesic use
Importance of early mobility.
Page 7: Flail Chest
Definition
Occurs with 3 or more consecutive rib fractures in multiple places leading to unstable chest wall. (unstable segment)
Results in paradoxical movement:
Inspiration: Flail segment retracts inward.
Expiration: Flail segment bulges outward.
Consequences
Leads to inadequate ventilation and increased work of breathing (WOB).
Page 9: Flail Chest: Physical Examination
Findings
Rapid, shallow respirations
tachycardia
bruise, tender
paradoxical movement of the chest wall
decreased breath sounds on the affected side
Asymmetrical chest movement
Signs of inadequate ventilation
Splinting and crepitus near fractured areas.
plural effusion
hypotension
Diagnostic Studies
Chest x-ray is the primary diagnostic method to assess rib injuries.
Prepare chest tube
Page 10: Flail Chest Treatment
Management Strategies
Ensure adequate lung expansion and adequate oxygenation.
Effective pain management.
High flow o2
Prepare for intubation
Additional interventions if necessary:
Intubation and mechanical ventilation.
Surgical fixation of ribs/ wiring.
Page 14: Pneumothorax
Definition
Condition caused by air entering pleural cavity.
Results in positive pressure that collapses the lung fully or partially.
Types
Open Pneumothorax: Identifiable external wound (e.g., sucking chest wound).
Closed Pneumothorax: No external wound present.
Spontaneous -
Latrogenic - Laceration from procedure
Tension - Rubbing
Hemothorax - Stab
Chylothorax - Lymph in plural space
Page 16: Pneumothorax Manifestations
Symptoms
Small Pneumothorax: Mild tachycardia, dyspnea.
Large Pneumothorax: Severe respiratory distress with rapid, shallow breaths, low oxygen saturation, and absent breath sounds over the affected area.
Diagnostic Tools
Chest x-ray to identify air/fluid in pleural space and assess lung volume reduction.
Page 19: Tension Pneumothorax
Seriousness
Life-threatening accumulation of air in the pleural space that prevents escape, causing increased pleural pressure.
Clinical manifestations include:
Severe dyspnea
Tachycardia
Tracheal deviation
Distended neck veins
Cyanosis and diaphoresis.
Page 22: Hemothorax and Chylothorax
Hemothorax
Presence of blood in pleural space due to various injuries.
Treatment typically requires a chest tube.
Low hemoglobin
Decrease breath sounds
Watch chest tube for large amounts of blood = call MD
Chylothorax
Presence of lymphatic fluid in the pleural space.
Treatment may involve conservative methods or surgery (pleurodesis) when necessary.
Page 23: Interprofessional Care for Pneumothorax
Care Approach
Cover wounds with a three-sided dressing to prevent air entry during inspiration and allow escape during expiration.
Stabilize impaled objects with bulky dressings without removal.
Page 24: Pneumothorax Treatments
Treatment Options
Utilization of chest tubes with water-seal drainage.
Immediate needle decompression for tension pneumothorax; followed by chest tube insertion.
Page 27: Nursing Considerations
Priorities for M.Z.
Focus on critical assessments and interventions related to M.Z.'s injuries and symptoms in preparation for medical procedures.
Cardia Tamponade
Monitor vital signs closely, paying special attention to blood pressure and heart rate changes.
Assess for signs of decreased cardiac output, such as altered mental status or peripheral cyanosis.
Prepare for potential interventions, including pericardiocentesis, to relieve pressure on the heart.
Signs & Symptoms
Muffled heart sounds
Medical emergency
Pericardiocentesis is a procedure used to remove excess fluid from the pericardial sac surrounding the heart.
