A police officer and a man whose life he saved shared an emotional exchange Wednesday. 

Pablo Campoverde, 24, says he came to visit family on Horton Street two weeks ago from Ecuador when he suddenly blacked out and stopped breathing.

Doctors say Campoverde had a heart arrhythmia. 

Officer Mike Costello, who was first on the scene, started doing chest compressions.

Doctors say this helped keep the blood moving in Campoverde's body - resulting in him not suffering any brain damage. 

Costello, a 23-year veteran of the police, says he was just doing his job.

Campoverde, who has made a full recovery, says he is grateful to Costello for what he did. Campoverde was set to go back to Ecuador tonight. 

He also says he has a follow-up with doctors in Stamford on his next visit next year.

Campoverde says every country should have this kind of medical care.
