    Study Notes

    Overview of Pulmonary Embolism (PE)

    • PE is an obstruction in the pulmonary artery or its branches, primarily caused by thrombus from the right side of the heart.
    • Other embolic sources include air, fat, amniotic fluid, and sepsis.

    Causes of Pulmonary Embolism

    • Fat embolism and multiple trauma increase risk.
    • Peripheral vascular disorders (PVDs) can contribute.
    • Abdominal surgery, immobility, and conditions leading to hypercoagulopathy are significant risk factors.

    Pathophysiology of Pulmonary Embolism

    • Thrombus formation is due to vascular wall damage, blood stasis, or hypercoagulability.
    • Trauma can lead to clot dissolution and changes in intravascular pressure.
    • Fragmented thrombus can travel to the right side of the heart and the lungs via the pulmonary artery, potentially causing further fragmentation or dissolution.
    • Occlusion of pulmonary arteries prevents surfactant production, leading to alveolar collapse and atelectasis.
    • A large embolus can completely block pulmonary vessels, resulting in death.

    Assessment Features

    • Common symptoms include restlessness, shortness of breath (SOB), dyspnea, and tachypnea.
    • Patients may experience stabbing chest pain, cyanosis, dilated pupils, and feelings of apprehension.
    • Additional signs can include diaphoresis, dysrhythmias, hypotension, fever, hemoptysis, and syncope.

    Potential Complications

    • Serious complications include pulmonary infarction, pulmonary hypertension, and embolic extension.
    • Other risks involve hepatic congestion, necrosis, pulmonary abscess, shock, ARDS, massive atelectasis, and right-sided heart failure.
    • Ventilation-perfusion mismatch can occur, leading to increased mortality.

    Diagnostic Tests

    • Common tests include chest X-ray, lung scan, pulmonary angiography, ECG, ABG measurements, thoracentesis, and plasma D-dimer test.

    Collaborative Management

    • Immediate oxygen therapy is critical.
    • Promote early ambulation and monitor obese patients; avoid leg massage.
    • Pain relief and elevation of the head of the bed enhance patient comfort.
    • Anticoagulation therapy involves heparin for two weeks, transitioning to Coumadin for 3-6 months.
    • Thrombolytic therapy and surgical options like pulmonary embolectomy or vena cava filter placement may be indicated.

    Nursing Interventions

    • Administer prescribed medications; IM injections should be avoided.
    • Monitor vital signs, respiratory status, and signs of DVT.
    • Encourage incentive spirometry use to promote lung function.

    Patient Education

    • Do's: Observe for bleeding, use soft toothbrushes, consider contraceptive options, and wear antiembolism stockings.
    • Don'ts: Avoid aspirin with Coumadin, restrictive leg clothing, prolonged immobility, smoking, and high-risk activities that can cause bruising.

    Key Points

    • PE is often a result of clots traveling from the legs to the lungs, leading to arterial blockage.
    • Risk factors include sluggish blood flow, vessel injury, and clotting abnormalities.
    • Sudden shortness of breath is the hallmark symptom of PE.
    • Diagnosis can be challenging due to non-specific signs and symptoms; imaging studies aid in detecting PE.
    • Treatment focuses on preventing further clots and may include medications, filters, or surgery.
