This study investigates the utilization of medical devices by nurses for monitoring anesthesia depth in critical care settings. Anesthesia depth monitoring is crucial in ensuring patient safety and optimizing anesthesia delivery during surgical procedures. However, the responsibility of monitoring anesthesia depth is often shared among healthcare providers, including nurses, in critical care settings. This research aims to explore the extent to which nurses are involved in using medical devices for monitoring anesthesia depth, their level of training and competency in utilizing these devices, as well as the challenges and barriers they face in performing this task. A mixed-methods approach will be employed, including surveys and interviews with nurses working in critical care units. The findings of this study will provide valuable insights into the role of nurses in anesthesia depth monitoring and contribute to enhancing patient safety and quality of care in critical care settings.
