To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Other interventions - target SpO2 98-100%
Other interventions - target SpO2 90-94%

Active comparator: target SpO2 98-100% - Post ROSC oxygen titrated to maintain SpO2 between 98-100%

Experimental: target SpO2 90-94% - Post ROSC oxygen titrated to maintain SpO2 between 90-94%


Other interventions: target SpO2 98-100%
Prehospital, post-ROSC oxygen maintained at =10L/minute of oxygen (equivalent to \~100% oxygen) into SGA/ETT if hand ventilated or 100% (i.e. FiO2 of 1.0) oxygen settings if mechanically ventilated. Patients will continue on treatment to handover in the ED. Between arrival at ED and first ABG in ICU, the oxygen setting may then be decreased provided SpO2 is maintained between 98-100%.

Other interventions: target SpO2 90-94%
Prehospital, post-ROSC oxygen reduced initially to 4L/minute (i.e. approximately 70% oxygen) into SGA/ETT if hand ventilated or an air mix setting if mechanically ventilated. If oxygen saturation remains =94% for 5 minutes, the oxygen flow rate will be further reduced to 2L/minute (i.e. approximately 46% oxygen) and hand ventilated to target an oxygen saturation between 90-94%. This treatment will continue to patient handover in the emergency department. Between arrival at ED and first ABG in ICU, oxygen will be titrated to target a oxygen saturation of 90-94%.
