Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: drugs - Oxygen

Experimental: Oxygen reduction - post-ROSC oxygen reduced to 2L per minute then delivered to maintain oxygen saturation 90-94% to hospital

Active Comparator: Standard Care - post-ROSC oxygen maintained =10L per minute to hospital


Treatment: drugs: Oxygen
oxygen delivery by ETT/ SGA connected to bag/valve/oxygen reservoir

Intervention code [1] 0 0
Treatment: drugs
Comparator / control treatment
Control group

Outcomes
Primary outcome [1] 0 0
