Method: This descriptive study was conducted with 210 neonatal nurses registered with the Neonatology Nursing Association between May and July 2024. Results: The average score was found to be 17.03 ± 7.79, which the nurses could obtain from the NIRS information form. This score shows that nurses have a moderate level of knowledge and awareness. It was found that there was a statistically significant difference in the level of knowledge and awareness of neonatal nurses about NIRS according to age (p = 0.049), education level (p < 0.001), years of working in the NICU (p = 0.007), having a neonatal nursing certificate (p = 0.006) and previous use of a NIRS spectrometer (p < 0.001). Conclusion: In this study, it was observed that the knowledge and awareness level of neonatal nurses about NIRS was at a moderate level. © 2025 Neonatal Nurses Associationeninfo:eu-repo/semantics/closedAccessNear-Infrared Spectroscopy (Nirs)NeonatalNeonatal NurseRegional OxygenationArticle2-s2.0-8521957257910.1016/j.jnn.2025.1016403Q231
