Huw Gaskin and Giorgio Baglioni were driving past the Bell Vue pub in Merthyr Tydfil, South Wales, when they spotted a man lying in the street.
The lads, who are both 17, quickly jumped out to help out the unidentified man, who was in his 30s.
Both chaps used CPR skills they'd been taught at air cadets and managed to bring the man back from the dead an amazing four times.
Paramedics then arrived on the scene and rushed the bloke to hospital where he is now recovering from a suspected heart attack.
Huw and Giorgio's life-saving actions were caught on CCTV as they took in turns to perform mouth-to-mouth and compressions on the victim who wasn't breathing, while helpless bystanders looked on.
Giorgio was quoted in the Daily Star explaining: "No-one knew CPR but we did."
And Huw added: "We would get him breathing but every time he was in the recovery position, he stopped breathing. The ambulance was called before we arrived. We just kept going."
Barry Canavan, who owns the pub and rang 999, said: "The boys did a great job – they are real lifesavers."
