Abstract
Aim
To understand whether the science to date has focused on single or multiple chest
compression components and identify the evidence related to chest compression components
to determine the need for a full systematic review.
Methods
This review was undertaken by members of the International Liaison Committee on Resuscitation
and guided by a specific methodological framework and the Preferred Reporting Items
for Systematic reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR).
Studies were eligible for inclusion if they were peer-reviewed human studies that
examined the effect of different chest compression depths or rates, or chest wall
or leaning, on physiological or clinical outcomes. The databases searched were MEDLINE
complete, Embase, and Cochrane.
Results
Twenty-two clinical studies were included in this review: five observational studies
involving 879 patients examined both chest compression rate and depth; eight studies
involving 14,285 patients examined chest compression rate only; seven studies involving
12001 patients examined chest compression depth only, and two studies involving 1848
patients examined chest wall recoil. No studies were identified that examined chest
wall leaning. Three studies reported an inverse relationship between chest compression
rate and depth.
Conclusion
This scoping review did not identify sufficient new evidence that would justify conducting
new systematic reviews or reconsideration of current resuscitation guidelines. This
scoping review does highlight significant gaps in the research evidence related to
chest compression components, namely a lack of high-level evidence, paucity of studies
of in-hospital cardiac arrest, and failure to account for the possibility of interactions
between chest compression components.
