(10:56 a.m. EDT) -- Carnival Breeze crew didn't hesitate in helping last weekend when a sick passenger required an onboard blood transfusion.

A 72-year-old male passenger with a "life-threatening" medical emergency required a donation of five liters of O-positive blood. Because of the man's condition, the U.S. Coast Guard decided it would be safer to treat him onboard and increase the ship's speed to arrive in Miami as soon as possible, Carnival spokesman Vance Gulliksen told Cruise Critic.

"An urgent announcement was made asking crew members with O-positive blood who wished to volunteer to proceed to the Carnival Breeze's medical center," Gulliksen said. "Within minutes, 42 crew members were at the medical center to donate blood."

The ship arrived in Miami just before 4 a.m. Sunday and disembarked the passenger, who is recovering at a Miami-area hospital.
