Cardiac arrest & resuscitation
Association of rescue breathing with outcomes in adult suffocation-related cardiac arrest
Authors' conclusion
In suffocation-related OHCA, the type of bystander CPR was not associated with improved neurological recovery.
Study context
- Population
- Adults with witnessed suffocation-related out-of-hospital cardiac arrest (OHCA), excluding cardiac-origin cases and those treated by EMS personnel, All-Japan Utstein Registry 2005–2023
- Participants
- 76,774 adults
- Exposure
- CCV-CPR or No cardiopulmonary resuscitation (CPR) vs CC-CPR by bystanders
- CC-CPRn = 39,451reference
- CCV-CPRn = 8,182
- No CPRn = 29,141
- Outcome
- Favorable neurological status
- Follow-up
- One month
Methodological detailsInverse probability of treatment weighting (IPTW)-adjusted, nationwide registry, prespecified subgroup analyses
- IPTW-adjusted
- Nationwide registry
- Prespecified subgroup analyses

One-month survival
- No significant difference for CCV-CPR vs CC-CPR
ROSC
