The care of critically ill patients undergoing mechanical ventilation in intensive care units requires continuous hemodynamic monitoring and a high level of nursing care intensity, generating scenarios of substantial workload that may influence physiological stability. The objective of this study was to analyze the relationship between nursing workload and hemodynamic variability in ventilated critically ill patients. The research followed a quantitative approach with a non-experimental cross-sectional design based on secondary data from clinical studies, epidemiological reports, and scientific literature related to intensive care. Data were systematized through analytical matrices and processed using multivariate statistical techniques, including multivariable logistic regression, structural equation modeling, and meta-analysis. Results showed that the Nursing Activities Score had a mean of 64.2% (SD = 8.1), indicating high care intensity. The incidence of adverse hemodynamic events reached 18.5%, while average ICU mortality was 11.3%. Logistic regression indicated that high NAS values significantly increased the probability of hemodynamic instability (OR = 1.84), whereas clinical severity doubled the risk of adverse events (OR = 2.14). Meta-analysis findings showed that high nursing workload environments increased adverse hemodynamic events up to 23.1% and extended ICU length of stay to 8.7 days. These findings indicate that nursing workload intensity significantly influences hemodynamic stability in critically ill ventilated patients.
