CPR Data Debriefing By Hospital Responders Improves CPR Performance And Increases Initial Survival Rate Following Cardiac Arrest

Royal Philips
Electronics (NYSE: PHG, AEX: PHI) announced the results of a study
confirming the benefit of using CPR sensing and recording technology to
improve CPR performance. Published in the Archives of Internal Medicine,
the study revealed that providing objective metrics and educational
feedback to medical personnel who performed CPR on a cardiac arrest patient
significantly improved ventilation rate, compression rate and depth of
compression. This improvement in CPR performance in a clinical setting was
associated with higher initial survival rates for cardiac arrest patients.


"Similar to post-game analysis for professional athletes, medical
responders were able to learn from their past resuscitation performance and
apply this knowledge to future resuscitations," said Dr. Dana Edelson,
director of Clinical Research for the Emergency Resuscitation Center at the
University of Chicago Medical Center, and co-investigator of the study.
"The results of this study suggest that CPR performance review has broad
applicability for improving resuscitation training."



Results drawn from medical professionals participating in the
Resuscitation with Actual Performance Integrated Debriefing (RAPID) trials
were published in the study, "Improving In-Hospital Cardiac Arrest Process
and Outcomes using Performance Debriefing." The Philips HeartStart MRx with
Q-CPR Measurement and Feedback was used to record resuscitation performance
during actual cardiac arrest events. Medical professionals then
participated in weekly debriefing sessions to review transcripts from the
prior week's resuscitations and analyze CPR performance including chest
compression rate and depth, ventilation rate, and undesired pauses in
compressions.



Only in recent years has it been possible to measure CPR performance in
a clinical setting. With its data collection and review capabilities, Q-CPR
allows resuscitation leaders in hospitals to use valuable feedback from
actual cardiac arrest cases to supplement classroom-based training
methodologies for professional responders.



The trial results demonstrate that CPR performance quality improved for
study participants who received post-resuscitation feedback compared to a
control group of professionals who did not receive educational
intervention. Specifically, the results show that:



-- During the educational intervention period, there was significant
improvement on CPR performance measures, compared to the control period
including:



-- Faster chest compressions



-- Deeper chest compressions



-- Decreased pauses in chest compressions, in general, as well as
around the time of defibrillation



-- Decreased ventilation rates



-- These improvements in CPR performance correlated with an increased rate
of initial survival (or "return of spontaneous circulation", also
termed "ROSC") in the RAPID group.
















In recent years, several studies documented that medical professionals
were performing poor CPR that deviated from consensus guidelines, despite
rescuer training and certification.(1)(2)(3) These studies were a catalyst
for the 2005 AHA Guidelines for Cardiopulmonary Resuscitation and Emergency
Cardiovascular Care to place a renewed emphasis on CPR training and
education.(4) Yet, two years later, there is still a need for novel CPR
training techniques to improve quality.



"As the trial demonstrates, balancing the correct number of breaths
with the exact depth and rate of chest compressions in real-life CPR
performance is actually a very complex process with a high likelihood of
human error," said Benjamin S. Abella, M.D. MPhil, assistant professor,
Department of Emergency Medicine, University of Pennsylvania, and
co-investigator of the study. "A focused educational debriefing program
using data provided by the HeartStart MRx with Q-CPR technology helps
emergency responders deliver quality CPR consistently, even in the most
stressful and fast-paced environments."



Quality CPR and early defibrillation are inextricably linked -- the
combination is essential to increase the survival rate for victims of
cardiac arrest. Q-CPR, available only on the Philips HeartStart MRx
Monitor/Defibrillator, is the first and only comprehensive technology
integrated into a monitor/defibrillator that provides real-time CPR
monitoring and feedback for both chest compressions and ventilations
(breaths). The technology, developed by Philips and Laerdal, offers medical
professionals corrective feedback on the rate and depth of chest
compressions, as well as the frequency and quality of ventilations,
encouraging them to adjust their technique as needed to improve CPR.



"Studies such as the RAPID trial reinforce the need to better integrate
CPR solutions with early defibrillation. We believe this to be the most
promising path to improving survival rates for the thousands of victims of
cardiac arrest each year," said Michael Miller, senior vice president of
Cardiac Care for Philips Healthcare. "As a worldwide leader in
resuscitation, Philips is dedicated to offering integrated solutions such
as the HeartStart MRx with Q-CPR, to raise the bar in quality of
resuscitation and ultimately improve patient outcomes."
