Although she had some swelling of the lips, tongue and the airway near the mouth, Nyad wouldn't need a long recovery, the doctor said, calling her stable and "very healthy."
Meanwhile, her website declared her team was in a mood to celebrate, with the words "Party Time."
Nyad jumped from the seawall of the Hemingway Marina into the warm waters off Havana Saturday morning to begin swimming. She paused occasionally for nourishment, but never left the water.
The support team accompanying her had equipment that generated a faint electrical field around her, designed to keep sharks at bay. A boat also dragged a line in the water to help keep her on course.
Sumaya Haddin, of Miami, had been tracking Nyad's swim before her family's weekend trip to Key West. She was surprised to see Nyad's flotilla from a parasail off Smather's Beach on Monday morning, thinking she wouldn't arrive for another day.
"You couldn't see her, you could just see the boats. It was very exciting," she said.
