As a CRRT nurse, your main responsibilities include setting up, monitoring, and troubleshooting the CRRT machine, closely monitoring patient vital signs and laboratory results, and adjusting treatment parameters under physician guidance. You will collaborate closely with nephrologists, intensivists, and other ICU staff to ensure appropriate and timely care. Documentation, patient education, and rapid response to any complications are also critical aspects of the role. The environment can be fast-paced and demands strong clinical judgment, but it offers rewarding opportunities to make a significant impact on patient outcomes in critical situations.
