The quality of manual chest compression is variable, and when low is deadly Abella et al, Circulation 2005

Manual chest compression may never be done adequately in selected settings

Take home message • Despite ongoing research for several decades, manual chest compression remains the gold standard means to perform cardiac massage. • Mechanical devices have several advantages in comparison to manual chest compression. • High-quality evidence is still lacking and a selected use of these devices is the safest approach until ongoing trials (e. g. CIRC, LINC and PARAMEDIC) are complete.
