Exploring the Role of Bispectral Index in Interrupting CPR for ROSC Diagnosis: A Call for Further Research

Abstract

The current approach in cardiopulmonary resuscitation (CPR) involves interrupting the chest compressions to assess the pulse and diagnose Return of Spontaneous Circulation (ROSC). This critical step is essential for determining the effectiveness of resuscitation efforts. However, the interruption of CPR poses a challenge, prompting researchers to explore alternative methods for diagnosing ROSC without compromising the ongoing resuscitation process. One potential solution proposed in the literature is the use of the Bispectral Index (BIS). BIS is a numerical value derived from processed electroencephalogram data, providing a measure of the depth of anesthesia or sedation. Some studies have reported an increase in BIS values following successful ROSC during CPR. This observation suggests that monitoring BIS levels could offer real-time information about cerebral perfusion and neurological status, eliminating the need for pulse checks that require CPR interruption. Despite these promising indications, it is crucial to acknowledge the limited existing literature on the subject. The evidence supporting the use of BIS in diagnosing ROSC during CPR is not yet robust, and further research is warranted. Researchers are encouraged to delve into this unexplored area, conducting comprehensive studies to assess the reliability and effectiveness of BIS as a tool for continuous monitoring during resuscitation efforts. In conclusion, while the concept of using BIS to diagnose ROSC during CPR holds potential, it remains an area that requires substantial research attention. The limited existing literature underscores the need for more extensive investigations to determine the feasibility and reliability of integrating BIS into the CPR protocol. As technology advances, exploring innovative approaches for continuous assessment during resuscitation becomes imperative for improving outcomes in cardiac arrest scenarios
