Hang on a mo - on a read of this, they said she wasn't a priority the previous day, when they assessed her. They probably didn't make a decision that she wasn't worth saving - they probably made a decision that she wasn't a priority for hospitalisation on the previous day, based on the symptoms she had on the previous day, which are probably the same as many people are experiencing with Covid 19.
They didn't just turn up and say they'd leave her to die. She just very sadly rapidly deteriorated - I'm sure that's utterly devastating for her family, but possibly not foreseeable based on the symptoms the previous day. Talking about the paramedic's "choice" in this way, as if she was choosing whether to help the woman live or not, is just misleading and unfair.
