Where should we compress? Ultrasound identification of the ideal area of maximal compression for CPR
Authors' conclusion
TTE-based anatomic mapping demonstrates that guideline-recommended chest compression location frequently overlies the LVOT rather than the iAMC, suggesting the possibility of physiologic mismatch between CPR hand placement and optimal ventricular compression.
Study context
- Population
- Adult emergency department patients and volunteersparticipants enrolled
- Participants
- 152 patients
- Exposure
- Guideline-recommended chest compression location aligns more closely with the left ventricular outflow tract (LVOT) than the ideal area of maximal compression (iAMC)
- Outcome
- Median horizontal distance from the sternum
Main finding
As reported in the abstract
Observational data: associations, not effects.
Further findings
Located within 1 cm of the sternum
Correlation of lateral positions of the LVOT and iAMC
- R
- 0.489; 95% CI, 0.357-0.601; p < 0.001
- Remained spatially distinct in most participants
Heat maps
- Overlap between the LVOT and the compression zone, while the iAMC was more lateral
iAMC position by prior intrathoracic surgery or overall body size
- No independent association between prior intrathoracic surgery or overall body size and iAMC position
- Multivariable analyses
