Domestic Care, Caregiver in the South of Cambridge, UK
I found this video. I thought it is useful information. If you are waiting for treatment, if the hospital is too full, or if doctors cannot reach you soon, you could look after yourself.
I post the video here for myself and for anyone who is interested in self-rescue.
