I would certainly have died then had it not been for the medical team, who immediately started cardiopulmonary resuscitation efforts as oxygen was being pumped into my lungs through the tracheostomy.

Within two minutes my heartbeat resumed, but during the next fifteen minutes or so, my heart stopped twice more—each time responding within about a minute to CPR.
