From Nashville, Tenn.: Christa Pike was administered two doses of pentobarbital and saline during an execution attempt, but she remained alive. Witnesses described her as having labored breathing and making sounds like she was choking. After the failed execution, Pike was taken to a hospital where she remains in critical condition on a ventilator.

Life-saving measures were performed on Pike, which has raised questions about the decision to do so given the original intention to execute her. Tennessee's lethal injection protocol outlines the procedures that the execution team must follow.

Further details about the events and the protocol are available, including the training requirements for the execution team and the circumstances surrounding Pike's hospitalization.
