Chest compression release velocity is independently associated with survival from out-of-hospital cardiac arrest

The association between chest compression release velocity and outcomes from out-of-hospital cardiac arrest

“…16 Preliminary findings from an observational human study by Bobrow et al, have reported a significant relationship between CCRV and survival to hospital discharge from OHCA. 17 Among 730 adult OHCA patients with CPR quality data, survival was greatest with CCRV > 400 mm/s (23%) compared to patients with CCRV 300-400 mm/s (12%) and those with CCRV < 300 mm/s (6%). Adjusted OR for survival were greatest for CCRV > 400 mm/s (OR = 3.86; 95% CI: 1.54, 9.66) and CCRV 300-400 mm/s (OR = 3.31; 95% CI: 1.50, 7.29) when compared to a reference group of CCRV ≤ 300 mm/s, which is consistent with our study findings.…”

“…Secondary outcomes were assessed in 10 mm/s increments of CCRV to be consistent with published literature in this area. 17 A pre-specified secondary analysis was performed to investigate the association between CCRV and survival to hospital discharge in the subgroup of patients who presented in ventricular fibrillation/ventricular tachycardia (VF/VT). Likelihood ratio tests determined appropriate inclusion of variables in the multivariable logistic regression model.…”

“…15,16 Preliminary findings from a recent observational study by Bobrow et al, appear to corroborate these animal findings. 17 The authors reported that mean CCRV "recoil" (per 10 mm/s) was independently associated with survival to hospital discharge.…”

Compliance with CPR quality guidelines and survival after 30 days following out‐of‐hospital cardiac arrest. A retrospective study

“…2 According to the uniform reporting of measured CPR quality guidelines and previous publications, specific CPR metrics to follow and report are episode duration, chest compression depth, chest compression rate, no-flow time, chest compression fraction (CCF) and chest compression release velocity (CCRV). [3][4][5][6] These variables have evidence-based referral values that are associated with better prognosis. 2,[5][6][7][8][9] Correspondingly, deviation from these referral values is associated with worse prognosis.…”

Amplitude-spectral area and chest compression release velocity independently predict hospital discharge and good neurological outcome in ventricular fibrillation out-of-hospital cardiac arrest

“…Leaning commonly occurs among rescuers 6,7,8,9 and therefore the avoidance of leaning was specifically identified as a CPR quality metric by the American Heart Association 10 . This has motivated the study of the release velocity as a quantitative measure of adequate chest recoil, and human data has linked a high release velocity to improved outcomes 11 . Nonetheless, patients with seemingly similar cardiac arrest Utstein characteristics and post resuscitation care can have drastically different outcomes.…”
