Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

17
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

19
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

20
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...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

138
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Chronic Obstructive Pulmonary Disease-V: Nursing Management

4.1K
Nursing management of Chronic Obstructive Pulmonary Disease (COPD) is crucial for providing thorough care and support to patients. Nurses play an integral role in this process through detailed assessment, careful planning, targeted interventions, and ongoing evaluation. Here's an overview of the critical steps in nursing management for COPD.

Summary

Acute pulmonary embolism (PE) management in Portugal is not standardized, lacking access to mechanical reperfusion. A new hub-and-spoke model proposes regional resource coordination for severe PE cases.

Area of Science:

  • Cardiology
  • Pulmonology
  • Health Services Management

Background:

  • Acute pulmonary embolism (PE) is a significant cause of death in Portugal, ranking third after stroke and myocardial infarction.
  • Current management of acute PE lacks standardization and access to critical mechanical reperfusion therapies.
  • This highlights a gap in timely and effective treatment protocols for severe PE cases.

Purpose of the Study:

  • To analyze existing clinical guidelines for percutaneous catheter-directed treatment in acute PE.
  • To propose a standardized management approach for severe forms of acute PE.
  • To develop a framework for regional resource coordination to establish an effective PE response network.

Main Methods:

  • Review and analysis of current clinical guidelines for PE management.
  • Development of a standardized treatment protocol for severe acute PE.
  • Proposal of a hub-and-spoke organizational model for regional resource coordination.

Main Results:

  • A standardized approach for severe acute PE management was proposed.
  • A methodology for coordinating regional resources was outlined, utilizing a hub-and-spoke design.
  • The proposed model aims to improve the effectiveness of PE response networks.

Conclusions:

  • The proposed hub-and-spoke model offers a standardized approach to managing severe acute PE.
  • This model facilitates regional resource coordination, enhancing PE response network efficiency.
  • Extending this model to a national level is recommended for broader impact.
