Well said, darkroom. I wonder if any of the crew were aware of the seriousness of the medical situation.
I fly 777's with more than 400 pax on board. If we were to call in the medics anytime someone on board wasn't feeling very well, we would probably never depart. There's always someone who has anxiety, headache, nausea or what have you.
Trick is to pick out the seriously ill ones. This is also something the gate agents should do BTW. And since hardly any cabin crew have had any sort of medical training, this can be very difficult.
