Kyle Busch's medical emergency has been partially revealed by 911 audio obtained by TMZ Sports ... with a caller saying the NASCAR superstar was struggling to breathe, overheating and coughing up blood before medics rushed to help.

The caller also confirmed the patient was still conscious at the time ... repeatedly telling dispatch, “He is awake. He's awake. He's awake.”

Kyle was known to use this testing facility extensively since joining Richard Childress Racing -- and according to the audio, he was lying on a bathroom floor inside the complex while employees prepared for paramedics to arrive.
