The frantic audio, which was obtained by TMZ, hears someone at his Miami mansion attempting to keep calm while telling the dispatcher that Rick Ross was "breathing hard", shaking and "throwing up blood".
'I know he's had seizures before. "He took his medicine earlier but he's not breathing right", he continued.
Ross's friend, whose name is withheld in the call, struggled to find the rapper's address as he spoke to emergency services. "You all right, help's on the way", the caller tells Ross.
The singer of Hustlin' and Aston Martin, Ross returned home from the hospital Monday after, according to published reports, he was hooked oxygen pump for parts of four days.
At the time of the call, Rick Ross, real name William Roberts, appeared to be unable to speak.
