In my research I came across a relatively large number of criminal manslaughter cases where death was caused by improper CPR administration (about 30 cases in 10 years all over Russia). The validity of the established practice remains to be established because Russian criminal law provides for immunity from criminal prosecution for harm done negligently in exceeding the limits of extreme necessity (Part 2 Article 39 of the Russian Criminal Code).
Trying to broaden my research a came across a vast number of articles on Good Samaritan Laws in the common law countries, and, as far as I understand, they provide immunity only for civil charges.
Is there any research on the criminal liability for providing improper emergency care or any case law on it?
