Final answer:
Venous air embolism is prevented by maintaining regular movement, using compression stockings or elastic bandages, and frequent leg elevation, particularly during long periods of immobility such as flights.
Step-by-step explanation:
To prevent venous air embolism, a serious medical condition where air bubbles enter the venous system, certain measures can be taken. Recommendations such as avoiding prolonged standing or sitting to prevent blood accumulation in the legs, using elastic bandages or compression stockings, ensuring frequent leg elevation, and encouraging movement during long travels are effective. For individuals with heart failure, like Ahaya, frequent walks and leg exercises are advised, particularly during long flights where the risk of deep vein thrombosis (DVT) is increased due to immobility and potential for blood pooling in legs.
