Abstract 108: Hemodynamic Effects of an Automatic Simultaneous Sternothoracic CPR Device in Patients with Cardiac Arrest
An automatic simultaneous sternothoracic CPR device (X-CPR®) is an apparatus performing CPR by providing simultaneous constriction of the thorax with a thoracic strap as well as compression of the sternum with a piston in a cycle. This study was conducted to compare hemodynamic effects of CPR using X-CPR with standard manual CPR in out-of-hospital cardiac arrest (OHCA) patients. Out of 62 adult patients with non-traumatic OHCA who arrived at emergency department, 24 patients (X-CPR group) received CPR using X-CPR and 38 patients (S-CPR group) received standard CPR. Acquisition and analysis of hemodynamic data was completed in 11 patients (46%) of X-CPR group and 14 patients (37%) of S-CPR group. Peak femoral arterial pressures and right atrial pressures during compression, right atrial pressures during relaxation, and end-tidal CO2 pressures were not different between two groups. Femoral arterial pressures during relaxation and calculated coronary perfusion pressures (CPP) were higher in X-CPR group than in S-CPR group (femoral arterial pressure during relaxation: median 20, interquartile range 10~37 vs. median 0, interquartile range -11~13 mmHg, p=0.002, CPP: median 10, interquartile range, 7~23 vs. median 2, interquartile range, -9~8 mmHg, p=0.017, respectively). In conclusion, CPR with an automatic simultaneous sternothoracic CPR device results in higher coronary perfusion pressure compared to standard CPR in patients with non-traumatic out-of-hospital cardiac arrest.
