Louisiana’s first execution using nitrogen gas is set to move forward as planned after a federal appeals court overturned a lower judge’s ruling Friday.

Under the state's new procedure, Hoffman will be strapped to a gurney and forced to breathe pure nitrogen gas through a full-face respirator mask. The protocol is nearly identical to that of Alabama, which became the first state to use nitrogen hypoxia as a method of execution last year.

A federal judge has halted Louisiana’s first death row execution using nitrogen gas, which was scheduled to take place next week.
