Man revived after being clinically dead for 40 minutes

An Australian man was brought back to life using a new resuscitation technique.

A 39-year-old Australian man was one of three cardiac arrest patients that doctors revived after they were clinically dead for between 40 and 60 minutes using two new emergency techniques.

Colin Fiedler had suffered a heart attack last June, and doctors used a new mechanical CPR machine, which performs chest compressions and a portable heart-lung machine to keep his blood circulating, FoxNews.com reported.

"I'm so grateful, more than I could ever say," he told the Herald Sun.
