It would seem so...
Fuddy certainly wore a fully inflated vest as this image shows:
But Mrs Briley, who had broken ribs and an injured sternum, would have required her life vest to be cut, and it was she who was flown to the hospital.
From the Yamamoto report; Yamamoto speaking here:
“...I then saw Mark Miller the Kalaupapa administrator and asked if Loretta was ok -he said that they were still rescuing people and he did not know, he then later told me
that she was ok and was being flown to Honolulu.
One of the Kalaupapa residents got me some dry clothes.
Then a few minutes later Mark told me that Loretta did not make it. ...
From the Maui News Briley story by Sugidono:
“...After some time, the Coast Guard picked up Fuddy and placed her beside Briley. He feared the worst when he noticed her brown hair, which looked identical to his wife’s.
...
Briley said Fuddy appeared to be “expired,” but he believed she was still alive. Some survivors believe she had died while waiting to be rescued.
“It was clear that she was unconscious, but her face was warm, which surprised me,” he said. “I thought about that afterwards: did she drown and could I have done something?” ...”
Both Mark Miller and Briley above (and possibly the coast guard rescuers) spoke as if Fuddy was alive after being picked up.
And there was a case of mistaken identity: from the Yamamoto report above, Fuddy had been put next to Mr. Briley, and Ms. Briley ended up near Yamamoto. (The excerpt below is also from the Yamamoto report; Yamamoto speaking)
“...I then saw a women covered in blankets and thought she was Loretta and asked her if she was ok -1 realized that it was not her. ...”

Thus we see an 'infant' life vest and the cartridges (one spent) as removed from the injured Mrs Briley before she was flown to hospital, leaving behind the vest which had been cut from her due to her injuries, and labelled FUDDY IN ERROR by the rescuers...and the vest that Fuddy wore is possibly one of two UNLABELLED adults vests shown above.
