“…The recommendation of the American Heart Association is that, in situations where specialized instrumental intubation has not been performed, 30 chest compressions at a depth of 5 cm at the center of the sternum and subsequent complete relaxation should be achieved at a rate of 100 to 120 compression per minute [ 4 ]. In situations where professional airway-securing surgery has not been performed, 30 chest compressions should be completed, and artificial ventilation should then be performed twice per second [ 5 , 6 ]. Alternatively, in patients who have undergone professional airway acquisition, chest compression should be performed for two minutes.…”

The purpose of this study was to evaluate the effect of real-time audio ventilation feedback on the survival of patients with an out-of-hospital cardiac arrest (OHCA) during advanced cardiac life support (ACLS) performed by paramedics. This research was a prospective randomized controlled study performed in Busan, South Korea, from July 2022 to December 2022. This study included 121 patients, ages 19 and up, who were transferred to the study site, excluding 91 patients who did not receive CPR under a doctor’s direction as well as those who had a ’(DNR)’ order among 212 adult CA patients. OHCA patients’ clinical prognosis was compared by being randomly assigned to either a general manual defibrillator (NVF) group (N = 58) or a manual defibrillator with an audio ventilation feedback (AVF) group (N = 63). To verify the primary outcome, the cerebral performance category (CPC), return of spontaneous consciousness (ROSC), 30h survival, and survival discharge were compared. Multivariate logistic regression was conducted to analyze the association between the audio-feedback manual defibrillator (AVF) and the ROSC of OHCA patients. This study analyzed 121 patients among 212 OHCA patients. The ROSC (AVF group: 32 {26.4%} vs. NVF group: 21 {17.3%}), 24 h survival (AVF group: 24 {19.8%} vs. NVF group: 11 {9.0%}), and survival discharge (AVF group: 12 {9.9%} vs. NVF group: 6 {4.9%}) were higher in the AVF group than the NVF group. However, upon analyzing CPC scores in the surviving patients between the two groups, there was no significant difference (AVF group: 4.1 ± 1.23 vs. NVF group:4.7 ± 1.23, p = 1.232). Multivariate logistic regression analysis showed that the use of AVF was associated with a higher ROSC (odds ratio {OR}, 0.46; 95% confidence interval {CI}, 0.23–0.73; p < 0.01) and higher survival at 30 h (OR, 0.63; 95% CI, 0.41–0.98; p = 0.01).

Background The purpose of this study was to conduct the effect of real-time audio ventilation feedback on the survival of out-of-hospital cardiac arrest(OHCA) patients during advanced cardiac life support(ACLS) performed by paramedics.Methods This study was a prospective randomized controlled study in Busan, South Korea from July 2022 to December 2022.The patients of this study were 121 aged 19 years or older who were transferred to the study institution excluding 91 patients who withholding CPR under doctor's direction and 'Do not resuscitation (DNR) state among 212 adult CA patients. OHCA patients were randomly assigned to compare clinical prognosis using a randomized a general manual defibrillator (NVF) group (N = 58) and a manual defibrillator with audio ventilation feedback (AVF) group (N = 63). To verify the primary outcome, the cerebral performance category (CPC), return of spontaneous consciousness(ROSC), 30 hours survival, and survival discharge were compared. And multivariate logistic regression was conducted to analyze the association of us between the audio-feedback manual defibrillator (AVF) and the ROSC of OCHA patients.Results This study analyzed 121 patients among 212 OCHA patients. The ROSC (AVF group: 32{26.4%} vs. NVF group: 21 {17.3%}), 24-hour survival (AVF group: 24 {19.8%} vs. NVF group: 11 {9.0%}), and survival discharge (AVF group: 12 {9.9%} vs. NVF group: 6 {4.9%}) were higher AVF group than NVF group. But, analyzed CPC scores in surviving patients between the two groups, there was no significant difference (AVF group:4.1 ± 1.23 vs. NVF group: 4.7 ± 1.23, p = 1.232). Multivariate logistic regression analysis showed that the use of AVF was associated with a higher ROSC (odds ratio {OR}, 0.46; 95% confidence interval {CI}, 0.23–0.73; P < 0.01) and higher survival at 30 hours (OR, 0.63; 95% CI, 0.41–0.98; p = 0.01).Conclusion The use of the audio ventilation feedback has been associated with a higher ROSC and higher survival at 30 hours after CA.
