Sensitive subject *** Medical negligence emergency!!

Can anybody that has dealt with looking into medical negligence give me a message!

Following questions :

- How long are you aloud to do CPR in a hospital?

( I thought it was max 20 minutes)

- and if said hospital done CPR for over a hour and made the patient suffer from severe brain damage which they didn’t have before.

Is that medical negligence?

I have a few more questions but somebody who has looked into this things comment and message me!!

Want to chew your ear off 😪

Thanks so much I advance.
