  • Implement quality improvement initiatives to enhance the identification and management of pulmonary embolism cases. Establish mechanisms for ongoing monitoring of patient outcomes and adherence to evidence-based practices.

Pathophysiology of Pulmonary Embolism (PE)

• Thrombus Formation:
  • Pulmonary embolism often originates from deep vein thrombosis (DVT), where a blood clot forms in the deep veins of the lower extremities or pelvis. This thrombus can dislodge and travel through the bloodstream.
• Embolization to Pulmonary Arteries:
  • The thrombus, now an embolus, can travel through the venous system, reaching the right side of the heart. From there, it can be propelled into the pulmonary arteries, causing a blockage.
• Obstruction of Pulmonary Vasculature:
  • As the embolus lodges in the pulmonary arteries, it obstructs blood flow to a portion of the lung, leading to impaired gas exchange and increased pulmonary vascular resistance.
• Pulmonary Infarction and Inflammation:
  • Severe cases of PE may result in pulmonary infarction, causing localized lung tissue damage. Additionally, the sudden obstruction triggers an inflammatory response, contributing to symptoms and complications.
• Hemodynamic Consequences:
  • The obstruction of pulmonary blood flow increases right ventricular afterload, leading to right ventricular strain. In severe cases, this can progress to right heart failure, causing systemic hypotension and compromised cardiac output.

Etiology of Pulmonary Embolism (PE)

• Deep Vein Thrombosis (DVT):
  • The most common cause of pulmonary embolism is the migration of a blood clot from a deep vein, typically in the legs or pelvis. Conditions promoting DVT include prolonged immobility, surgery, trauma, and certain medical conditions.
• Hypercoagulable States:
  • Individuals with hypercoagulable conditions, such as inherited clotting disorders or acquired conditions like antiphospholipid syndrome, are at an increased risk of developing blood clots that may lead to pulmonary embolism.
• Venous Stasis:
  • Conditions that promote venous stasis, such as prolonged bed rest, long flights, or congestive heart failure, contribute to the development of clots that can embolize to the pulmonary arteries.
• Trauma or Surgery:
  • Surgical procedures, particularly orthopedic surgeries, can increase the risk of clot formation. Trauma, especially fractures or extensive soft tissue injuries, can also predispose individuals to PE.
• Cancer and Chemotherapy:
  • Cancer, especially certain types like lung, pancreatic, or ovarian cancer, is associated with an increased risk of developing blood clots. Additionally, some chemotherapy agents can contribute to hypercoagulability.

Desired Outcome for Pulmonary Embolism Nursing Care

• Effective Oxygenation:
  • Ensure adequate oxygenation and maintenance of optimal oxygen saturation levels to prevent hypoxia and support respiratory function.
• Hemodynamic Stability:
  • Maintain hemodynamic stability by preventing further right ventricular strain, optimizing cardiac output, and preventing complications such as shock.
• Pain Management:
  • Alleviate and manage pain associated with pulmonary embolism, promoting the patient’s comfort and facilitating participation in therapeutic activities.
• Prevention of Complications:
  • Minimize the risk of complications such as deep vein thrombosis, recurrent embolism, and pulmonary infarction through timely and appropriate interventions.
• Patient Education and Psychosocial Support:
  • Provide comprehensive patient education on anticoagulant therapy, signs of recurrence, and lifestyle modifications to prevent future clots. Offer psychosocial support to address emotional and psychological aspects of the diagnosis.

Subjective Data:

• Reports sudden onset of chest pain, described as sharp or stabbing.
• Complains of shortness of breath, especially upon exertion.
• Describes a feeling of anxiety or impending doom.
• Reports recent history of prolonged immobility, such as a long flight or bed rest.
• Mentions a personal or family history of deep vein thrombosis (DVT).
• Expresses awareness of risk factors, such as recent surgery or trauma.
• Reports cough, possibly with hemoptysis (coughing up blood).

Objective Data:

• Elevated respiratory rate (tachypnea).
• Increased heart rate (tachycardia).
• Decreased oxygen saturation levels.
• Crackles or wheezing upon lung auscultation.
• Presence of a pleuritic rub on chest examination.
• Signs of deep vein thrombosis (DVT) if present, such as unilateral leg swelling and tenderness.
• Abnormal findings on imaging studies (CT pulmonary angiography, ventilation-perfusion scan).
• Signs of right ventricular strain on electrocardiogram (ECG).
• Elevated D-dimer levels.
• Hypotension or a drop in blood pressure.

Nursing Assessment for Pulmonary Embolism

• Respiratory Assessment:
  • Monitor respiratory rate, depth, and pattern to identify signs of respiratory distress, such as increased respiratory rate, dyspnea, and use of accessory muscles.
• Oxygenation Status:
  • Assess oxygen saturation levels using pulse oximetry. Maintain SaO2 within the target range and intervene promptly if levels fall below the acceptable range.
• Cardiovascular Assessment:
  • Monitor vital signs regularly, paying close attention to heart rate, blood pressure, and signs of right ventricular strain. Assess for the presence of jugular venous distension and peripheral edema.
• Pain Assessment:
  • Evaluate the patient’s pain intensity, location, and characteristics. Use a pain scale to assess and document pain regularly. Implement appropriate pain management strategies.
• Neurological Assessment:
  • Monitor neurological status, including mental status, orientation, and response to stimuli. Note any changes in consciousness or neurological deficits that may indicate complications.
• Laboratory Monitoring:
  • Regularly assess laboratory values, including D-dimer, to aid in the diagnosis and monitor the effectiveness of anticoagulant therapy. Monitor for signs of bleeding related to anticoagulation.
• Mobility and Ambulation:
  • Encourage and assess the patient’s mobility, promoting early ambulation when appropriate to prevent venous stasis and enhance overall circulation.
• Psychosocial Assessment:
  • Evaluate the patient’s emotional and psychological well-being, addressing anxiety, fear, and concerns related to the diagnosis of pulmonary embolism. Collaborate with other healthcare professionals for additional support.

Interventions and Rationales

• Administer Oxygen Therapy:
  • Rationale: Increases oxygen levels, addressing hypoxemia associated with pulmonary embolism, and supports respiratory function.
• Initiate Anticoagulant Therapy (e.g., Heparin):
  • Rationale: Prevents further clot formation and reduces the risk of additional emboli, promoting anticoagulation.
• Administer Analgesics for Pain Management:
  • Rationale: Relieves chest pain, promoting comfort and reducing anxiety, which can improve respiratory effort.
• Implement Bed Rest:
  • Rationale: Reduces oxygen demand and minimizes the risk of dislodging clots, preventing further complications.
• Monitor Vital Signs Closely:
  • Rationale: Allows for early detection of changes in respiratory rate, heart rate, and blood pressure, providing prompt intervention if needed.
• Assist with Diagnostic Tests (e.g., CT Angiography, D-dimer):
  • Rationale: Aids in confirming the diagnosis and determining the extent of pulmonary embolism for appropriate management.
• Elevate Legs and Encourage Ambulation (when appropriate):
  • Rationale: Enhances venous return and reduces the risk of deep vein thrombosis (DVT), a common precursor to pulmonary embolism.
• Provide Emotional Support and Education:
  • Rationale: Addresses anxiety and fear, enhances coping mechanisms, and educates the patient on medication adherence and lifestyle modifications.
• Prepare for Surgical Intervention (Embolectomy or Vena Cava Filter Placement):
  • Rationale: In cases of severe or recurrent pulmonary embolism, surgical interventions may be necessary to remove or prevent further emboli.
• Collaborate with Respiratory Therapy for Breathing Exercises:
  • Rationale: Promotes optimal lung function, assists in preventing atelectasis, and supports respiratory recovery.
