Honolulu lifeguards on Monday evening helped resuscitate a 25-year-old surfer at Pipeline on Oahu’s North Shore.

Honolulu Ocean Safety received a 911 call just after 6:30 p.m. for a man who was found unresponsive in the ocean.

At the time, the lifeguard tower at Ehukai Beach had just closed, but lifeguards were still in the parking lot when beachgoers alerted them of the incident.

Surfers helped bring the man close to shore, and with the help of lifeguards, brought him up onto the sand to start CPR. After several cycles of CPR, according to Ocean Safety, the man regained a pulse.

Honolulu Emergency Medical Services and the Honolulu Fire Department also responded.

EMS took over with advanced life-saving treatment and transported the man to the hospital in critical condition.
