BACKGROUND: Out-of-hospital cardiac arrest is a major public health problem with over 90% case fatality. Although it is known that good quality of cardiopulmonary Resuscitation (CPR) leads to improved patient outcomes, health care practitioners commonly perform sub-optimal CPR.The aim of this study was to evaluate the effectiveness of this device which was designed and made by the our technician study group member in improving CPR operations.
METHODS: : This cross-sectional study was performed on patients who have suffered from cardio-pulmonary arrest in Al-Zahra Hospital in 2020. Patients needed primary CPR for any reason, were randomly divided into two groups using random allocation software. The first group contains patients as the CPR Feedback device is on and alarm is on and warns, if resuscitation is ineffective, the second group also uses the device, but with the difference that the alarm is off. The data was analyzed by general linear model method (repeated measure ANOVA).
RESULTS: The results showed that there was no significant interaction between group and time for the massage depth variable and there was no significant difference in the depth of massage between the two groups. For the rate of massages, there was a significant interaction between group and time. The between-group effect which showed the difference in the number of massages in the two groups, was statistically significant.
CONCLUSION: These results indicated that turning on the CPR feedback device's warning increases the rate of massages during CPR and, as a result, makes it more effective.
