Pulmonary Embolism I: Introduction

Pulmonary Embolism I: Introduction

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 Hypertension: Classification and Pathogenesis

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

Area of Science:

Pulmonology
Internal Medicine

Background:

Haemoptysis is a significant clinical presentation with potentially severe outcomes.
Prompt assessment of severity and patient status is critical.

Purpose of the Study:

To outline the common etiological categories of haemoptysis.
To emphasize the importance of thorough clinical evaluation for diagnosis and management.

Main Methods:

Review of common causes of haemoptysis.
Emphasis on detailed history-taking and physical examination.
Discussion of diagnostic criteria and referral guidelines.

Main Results:

Haemoptysis causes are categorized into infective, neoplastic, vascular, autoimmune, and drug-related.
Clinical assessment is key to determining haemodynamic status.
Clear criteria exist for investigations and specialist referral.

Conclusions:

Effective management of haemoptysis hinges on accurate diagnosis and risk stratification.
Physicians need a strong understanding of diagnostic pathways and when to escalate care.
