Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

46
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Pulmonary Embolism III: Nursing Management

42
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Pneumothorax-II

366
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Pneumothorax-I01:26

Pneumothorax-I

345
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

Area of Science:

  • Pulmonary medicine
  • Vascular radiology
  • Diagnostic imaging

Context:

  • Pulmonary arterial circulation is a pathway for systemic venous emboli.
  • Endogenous and exogenous substances can migrate, leading to significant clinical outcomes.
  • Non-cruoric emboli pose diagnostic and therapeutic challenges.

Purpose:

  • To highlight the role of CT scanning in identifying pulmonary arterial circulation issues.
  • To emphasize the diagnostic capabilities of CT in visualizing endoluminal defects.
  • To assess the impact of emboli on pulmonary parenchyma.

Summary:

  • Substances migrating from systemic veins into pulmonary arteries can cause severe consequences.
  • Computed tomography (CT) scanning is essential for diagnosing these emboli.
  • CT imaging reveals endoluminal defects and evaluates pulmonary parenchymal damage.
