Cardiac arrest & resuscitation
Transthoracic impedance variability to assess quality of chest compression in out‐of‐hospital cardiac arrest
Authors' conclusion
In this population, consistency of chest compression maneuver, measured by variability in TTI, was an independent predictor of defibrillation outcome.
Study context
- Population
- Out-of-hospital cardiac arrest (OHCA) with shockable rhythm565 matched long-term outcomes
- Participants
- 680 participants
- Exposure
- ImpCC variability vs chest compression fraction (CCF) as predictors of defibrillation success
- Outcome
- Defibrillation success

Main finding
As reported in the abstract
- ImpCC significantly higher with unsuccessful vs successful defibrillation
- p = .0002
Observational data: associations, not effects.
Secondary outcomes
Long-term outcomes (ROSC and survival)
- Neither ImpCC nor CCF associated with long-term outcomes
