Hyperbaric oxygen treatment for air or gas embolism
Summary
Arterial gas embolism (AGE) and venous gas embolism (VGE) occur from gas entering circulation. AGE causes stroke-like symptoms, while VGE may be tolerated or lead to serious complications.
Area of Science:
- Medical Science
- Physiology
- Emergency Medicine
Background:
- Gas embolism, including arterial (AGE) and venous (VGE), arises from alveolar-capillary disruption or tissue bubble formation.
- Causes include diving, altitude exposure, surgery, and iatrogenic gas injection.
- AGE presents with neurological deficits, while VGE may be filtered by lungs or cause systemic issues.
Purpose of the Study:
- To review the pathophysiology, clinical manifestations, and treatment of arterial and venous gas embolism.
- To discuss diagnostic challenges and the role of imaging.
- To present an evidence-based review of adjunctive therapies for gas embolism.
Main Methods:
- Literature review of existing studies on gas embolism.
- Analysis of pathophysiology and clinical presentations.
- Evaluation of treatment strategies, including hyperbaric oxygen therapy.
Main Results:
- AGE typically causes neurological deficits; VGE is often asymptomatic but can lead to pulmonary edema or AGE.
- Radiographic imaging is unreliable for excluding AGE.
- Treatment for AGE mirrors decompression sickness, emphasizing oxygen and hyperbaric oxygen therapy.
Conclusions:
- Understanding the distinct mechanisms and consequences of AGE and VGE is crucial for diagnosis and management.
- Prompt recognition and appropriate treatment, particularly hyperbaric oxygen, are vital for AGE.
- Further research into adjunctive therapies for cerebral AGE is warranted.

Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...

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 (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...

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...

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.

2.1K
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.
