An air bubble blocking circulation is called?

• A. Air Embolism
• B. Barotrauma
• C. Altitude Sickness
• D. Wet Drowning

Answer: (A)

An air bubble blocking circulation is an air embolism. When air enters the bloodstream, it can form bubbles that travel and lodge in vessels, cutting off blood flow to tissues. This can cause tissue ischemia and organ dysfunction depending on where the blockage occurs. Air embolism can arise from invasive lines, trauma, surgical procedures, or rapid decompression. Clinically, the emphasis is on removing or preventing more air from entering, giving high-flow oxygen to help dissolve the bubbles, and using more advanced measures like hyperbaric oxygen therapy if the situation is severe. The other conditions involve different mechanisms: barotrauma is injury from pressure changes outside the vessels, altitude sickness stems from hypoxia at high elevation, and wet drowning involves aspiration of water into the lungs rather than intravascular air.
