Cardiac arrest & resuscitation
Outcomes following impedance threshold device use during out-of-hospital cardiac arrest
Main finding · Return of spontaneous circulation (ROSC)Result — go to the resultAOR for ROSC 1.09 CI 1.04–1.14Authors' conclusion
ITD use was associated with improved prehospital outcomes but worsened dispositional outcomes among patients experiencing OHCA, suggesting this device may prove beneficial early in resuscitation of OHCA patients.
Study context
- Population
- Adult, non-traumatic, OHCA scene runs from the 2024 ESO Data Collaborativepatient records (85.3% no impedance threshold device (ITD), 13.1% ITD only, 1.6% ITD + ACD)
- Participants
- 97,439 participants
- Comparison
- ITD only; ITD and active compression-decompression device (ITD + ACD); and neither device (no ITD)
- Outcome
- Return of spontaneous circulation (ROSC)
Methodological detailsmultivariate logistic regression, adjusting for demographics and several potential confounders
- Multivariate logistic regression

Main finding
As reported in the abstract
AOR for return of spontaneous circulation (ROSC)
1.09
CI 1.04–1.14
By group
ITD only vs no ITD
aOR for ROSC 1.09 (CI 1.04–1.14)
Further findings
| Outcome | ITD only | No ITD | aOR for survival to discharge (CI) | |
|---|---|---|---|---|
| Survival to hospital dischargeITD only vs no ITD | 23.9% | 32.0% | 0.68 (0.61–0.76) | |
| 0.512AOR for survival to discharge (log scale) |
- Survival to hospital discharge: survival to discharge was lower for patients treated with ITD only
Survival to hospital arrival (SHA)
- A similar pattern emerged for SHA
Favorable neurologic outcome (discharge to home)
- A similar pattern emerged for favorable neurologic outcome
ITD + ACD group
- The ITD + ACD group showed more extreme versions of the trends observed for ITD only
Availability of disposition outcomes
- Disposition outcomes available
- 13,026 patients (13.4%)
