Is it possible to get an air embolism from an IV? I had an IV the other day and was given comprazine. It made my heart rate go way up. Any reason why?

No air embolism. You did not have air embolism. Yes, a bubble or two of air may have gotten into your venous circulation. That's it. Air embolism occurs when a larger volume of air is injected, usually under pressure. You likely experienced a side effect of the drug or a symptom of the condition it was treating. .
