Acute cardiac care & resuscitation
Hemodynamic effects of TEE–guided adjustment of the area of the maximal compressions during cardiopulmonary resuscitation
Authors' conclusion
2D-TEE-guided identification and adjustment of AMC allowed targeted optimization of chest compressions. Approximately 80% of patients required AMC adjustment. 3D-TEE was used to quantify LV parameters. In patients undergoing AMC adjustment, significant improvements in SV and EF were observed, reaching levels comparable to those without adjustment.
Study context
- Population
- Adult patients with non-traumatic out-of-hospital cardiac arrest (OHCA)patients included
- Participants
- 19 patients
- Exposure
- Left ventricular (LV) parameters during resuscitation with and without area of maximal compression (AMC) adjustment
- AMC-LV groupn = 4
- AMC-non-LV groupn = 15
- Outcome
- AMC location

Further findings
ROSC rates · did not differ
P = 0.603
- Stroke volume (SV), ejection fraction (EF) and EtCO2 before vs after adjustment in the AMC-non-LV group
- 9 vs. 28.6 mL, p = 0.004 · SV · EF 20.4 vs. 60.8%, p < 0.0001 · EtCO2 19 vs. 42 mmHg, p < 0.0001
SV, EF and EtCO2 before vs after adjustment in the AMC-non-LV group
- Increased significantly post-adjustment, reaching values comparable to the AMC-LV group
