If a scuba diver complains of shortness of breath and severe muscle and joint pain immediately after ascending from a dive. he is cyanotic and is coughing up bloody froth. We suspect Air embolism.
<h3>
What is air embolism?</h3>
An air or gas embolism is a bubble that becomes trapped in a blood vessel and blocks it.
<h3>
Why does air embolism take place?</h3>
It is possible for a scuba diver if:
- spends too much time underwater
- emerges too rapidly
- holds their breath when they rise
Air can enter the blood arteries from the lungs (arterial gas embolism) or nitrogen bubbles can form in the blood vessels (decompression sickness or "the bends").
Air or gas embolisms can result in life-threatening diseases such as a stroke or heart attack.
