Insights

The BLUE protocol aids acute dyspnea diagnosis. Focused Echocardiography (FECHO) enhances diagnosis, particularly for pulmonary embolism (PE), even with COVID-19.

Area of Science:

  • Emergency Medicine
  • Cardiology
  • Pulmonology

Background:

  • Acute dyspnea presents a diagnostic challenge.
  • The BLUE protocol is a structured approach for dyspnea diagnosis.
  • Pulmonary embolism (PE) and COVID-19 are significant causes of acute dyspnea.

Observation:

  • Focused Echocardiography (FECHO) can be integrated with the BLUE protocol.
  • COVID-19 can manifest with thrombotic events like PE.
  • Lung ultrasound may not show parenchymal changes in COVID-19-associated PE.

Findings:

  • Adding FECHO to the BLUE protocol improves diagnostic accuracy for acute dyspnea.
  • FECHO is particularly valuable in diagnosing submassive and massive PE.
  • COVID-19-related PE may lack typical lung ultrasound findings.

Implications:

  • Integrating FECHO into the BLUE protocol offers a more comprehensive diagnostic strategy.
  • This approach aids in timely diagnosis and management of PE, including in COVID-19 patients.
  • Enhanced diagnostic capabilities can improve patient outcomes for acute respiratory conditions.

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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Imaging Studies for Cardiovascular System II:Types of Echocardiography

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Ultrasonography01:17

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
