Summary
A novel ventilation strategy helps prevent air embolism after cardiopulmonary bypass (CPB). This method, used with surgical de-airing, reduces residual air in the left heart and pulmonary veins, confirmed by transesophageal echocardiography.
Area of Science:
- Cardiovascular Surgery
- Anesthesiology
- Pulmonary Medicine
Context:
- Air embolism remains a risk following cardiopulmonary bypass (CPB), even with CO2 administration.
- Residual air in the left heart and pulmonary veins can lead to serious complications.
- Current de-airing techniques may not completely eliminate this risk.
Purpose:
- To present a complementary method for reducing air embolism after CPB.
- To describe a specific ventilation strategy to clear air from the pulmonary veins.
- To validate the effectiveness of this technique using transesophageal echocardiography (TEE).
Summary:
- A technique involving lung re-inflation and controlled ventilation (10 breaths/minute) is initiated after CPB.
- The heart is filled from the heart-lung machine concurrently with ventilation.
- This method complements surgical de-airing to minimize air in the left heart and pulmonary veins.
Impact:
- Provides an additional safety measure against air embolism in cardiac surgery patients.
- Potentially reduces the incidence of neurological and systemic complications associated with air bubbles.
- Offers a practical, echo-guided approach to enhance patient safety post-CPB.

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...

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...
