The following is the revive priority that you must follow whilst being on duty as NHS:
NHS > MET Police > Civilian
At all times medics should value their life. Therefore entering an active combat situation would be poor value of life. This also means you should not revive anyone involved in a combat scenario. You must wait at least 3 minutes before entering an area that was previously a combat situation (wait 3 minutes after the last gunshot has been fired,If Police are on scene ask For permission to Treat before you enter the situation).
We do not use DNRs on this community, we believe that everyone should get a fair chance at revival and to get to experience the roleplay that is brought into the server by the faction, if anyone is caught not reviving certain people they will be suspended. The exception to this is when they have been clearly killed, for example, shot in the head, blown up or anything that is clearly unable to be treated for.
