Abstract

Purpose:  The purpose of this study is to investigate the effectiveness of brain reginal oxygen saturation (rSO2) measurements by emergency medical stuff (EMS) on ambulances for goal directed cardio pulmonary resuscitation (CPR) in out of hospital cardiac arrest (OHCA) patients. Methods: We studied consecutive 114 cases of OHCA transported to 2 facilities in 8 ambulances. Results: We could measure rSO2 values in 33 of the 114 cases. We measured the increase in rSO2 value in 20 (69%) of the 29 cases without prehospital return of spontaneous circulation (ROSC). However, in 10 (30%) of all 33 cases, we also observed “mostly dead cases” whose rSO2 value does not be elevated after CPR and / or ROSC. The rising rSO2 value by CPR by EMS on ambulance was higher in patients with in patients with survival after 90 days (n=2) than in those who did not survive after 90 days (n=31) (median [IQR]; 36[32-40] % versus 0[0-6] %, p=0.07). In some cases we confirmed that ROSC and pulseless electronical activity can detect early rSO2 measurements (Figure). In 21 (66%) of the 33 cases, the rSO2 value was the lowest (=15%) at the start of measurement in the ambulance, suggesting the existence of a “transport gap,” which makes it difficult to maintain the quality of CPR during patient movement to an ambulance. Conclusion: These findings indicated that rSO2 measurements in OHCA patients may be useful for monitoring the quality of CPR evaluation, which enable goa-l-directed CPR. Conclusion: These findings indicated that rSO2 measurements in OHCA patients may be useful for monitoring the quality of CPR evaluation, which enable goa-l-directed CPR.
