Honestly, I don't find it all that surprising. Men are wise to err on the side of caution when it comes to even the appearance of improper behavior and I could see how many might freeze up in such a situation, even if they knew CPR.
I remember a woman talking about how some kids were running around naked near their house and he had to call her, and she was kind of grumbling about how he wouldn't just handle it himself. I had to explain that I would have done exactly the same. There is no WAY as an adult male I'd be accosting underage naked children and asking where their parents were, etc., unless they were in danger of freezing or other dangers. This woman was acting like her husband was being lazy and/or a wuss. He was just using his head.
You can thank our society for this bullshit. It is because we put women on a pedestal in our society and men have been relegated to being the butt of jokes or the quiet backbones of the working class who have no right to complain, and if they dare not fit into those two categories, they are then accused of toxic masculinity or something similar.
