ZOLL Medical Corporation Announces Positive Results from Two Clinical Studies on AutoPulse Device

Strategic Insights

— 2 min read

Cardiac arrest patients undergoing treatment with the ZOLL AutoPulse Noninvasive Cardiac Support Pump in out-of-hospital settings showed significant improvements in short-term survival rates. The results of two studies conducted in Richmond, Virginia and San Francisco, California, were presented at the 2005 Annual Meeting of the National Association of Emergency Medical Services Physicians (NAEMSP). These findings further validate the efficacy of the AutoPulse in increasing return of spontaneous circulation (ROSC) in cardiac arrest patients.

Key Takeaways:

  • The first study, conducted in Richmond, Virginia, found a 74% relative increase in ROSC in patients treated with the AutoPulse compared to standard CPR practices.
  • The improvement in ROSC occurred regardless of the patient's initial cardiac rhythm, with the ROSC percentage rising from 21.6% to 37.5% after transitioning to the AutoPulse.
  • The second study, conducted in San Francisco, California, found that the AutoPulse improved delivery of patients with beating hearts to the Emergency Department (ED) by 35%.
  • The San Francisco study also found that the use of the AutoPulse was associated with increased ROSC to ED compared to manual CPR (39% vs. 29%, p=0.003).
  • The AutoPulse device offers the benefit of freeing up rescuers to focus on other life-saving interventions by compressing the entire chest in a unique, "hands-free" manner.
  • To date, more than 100 customers have purchased the AutoPulse and have been actively using it as part of their resuscitation protocols.

Statistics:

  • The AutoPulse Noninvasive Cardiac Support Pump showed a 74% relative increase in ROSC compared to standard CPR practices (Study 1).
  • The ROSC percentage rose from 21.6% to 37.5% in patients treated with the AutoPulse (Study 1).
  • The AutoPulse improved delivery of patients with beating hearts to the ED by 35% in the San Francisco study.
  • The use of the AutoPulse was associated with increased ROSC to ED in 39% of cases compared to 29% with manual CPR (San Francisco study).
