Summary
Background
Cardiopulmonary resuscitation (CPR) quality during actual cardiac arrest has been
found to be deficient in several recent investigations. We hypothesized that real-time
feedback during CPR would improve the performance of chest compressions and ventilations
during in-hospital cardiac arrest.
Methods
An investigational monitor/defibrillator with CPR-sensing and feedback capabilities
was used during in-hospital cardiac arrests from December 2004 to December 2005. Chest
compression and ventilation characteristics were recorded and quantified for the first
5 min of resuscitation and compared to a baseline cohort of arrest episodes without
feedback, from December 2002 to April 2004.
Results
Data from 55 resuscitation episodes in the baseline pre-intervention group were compared
to 101 resuscitations in the feedback intervention group. There was a trend toward
improvement in the mean values of CPR variables in the feedback group with a statistically
significant narrowing of CPR variable distributions including chest compression rate
(104 ± 18 to 100 ± 13 min−1; test of means, p = 0.16; test of variance, p = 0.003) and ventilation rate (20 ± 10 to 18 ± 8 min−1; test of means, p = 0.12; test of variance, p = 0.04). There were no statistically significant differences between the groups in either
return of spontaneous circulation or survival to hospital discharge.
Conclusions
Real-time CPR-sensing and feedback technology modestly improved the quality of CPR
during in-hospital cardiac arrest, and may serve as a useful adjunct for rescuers
during resuscitation efforts. However, feedback specifics should be optimized for
maximal benefit and additional studies will be required to assess whether gains in
CPR quality translate to improvements in survival.
