Not necessarily - what I was thinking of is any day-to-day emergency - say a car accident (but it could be an elderly person and a carer I suppose) - then an ordinary person could have a conversation with emergency medical people in real-time (ie while they are waiting for the ambulance to arrive) and he / she could be showing the emergency people the actual situation . . of course the start of the jitsi process would have triggered a call to the ambulance at the same time as well . .
Yes, of course. Depending on the the person who needs the medical attention - if they are alone it is out of the question - in that case I am more interested in implantable devices which can monitor vital signs and produce electronic warnings of some sort - but that is another exercise . .
I am not sure what part you say is currently not possible - you have a citizen first-responder with the Jitsi app on their phone and you have eg the local ambulance station with jitsi on the desktop and an ambulance in the field with a phone. If there is already an agreed-upon room set up, if the citizen enters the room, doesn’t this alert other members who have access to the room?
If I can see a way forward I would be happy to pay someone to do what I want.
