AB  - Objectives: To evaluate the clinical relevance of Integrated Pulmonary Index (IPI) monitoring during transbronchial needle aspiration (EBUS-TBNA) under sedation and determine whether it reduces hypoxic events compared to standard monitoring.Methods: This prospective observational research was carried out at Dr. Lutfi Kirdar City Hospital, Istanbul, Turkey, between July 2022 and July 2023. A total of 50 patients, aged 18-80 years with American Society of Anesthesiologists scores of I-III, undergoing EBUS-TBNA with deep sedation for diagnostic purposes were included. The IPI values were measured at 6 time points: baseline, induction, 3, 5, 10 minutes, and at the end of the procedure. Patients were categorized based on whether their IPI scores were above 7 (group 1) or below 7 (group 2).Results: A total of 43 patients completed the study. Group 1 had higher end-tidal carbon dioxide and respiratory rate at multiple time points, including induction and at 3, 5, and 10 minutes post-induction (p<0.05). Group 2 experienced a higher rate of apnea at these times (p<0.05). Those with lower IPI scores (namely, IPI=3 and IPI=4) showed significantly higher apnea rates, while those with higher scores (namely, IPI=7 and IPI=8) were less likely to have apneic episodes.Conclusion: The IPI monitoring during EBUS-TBNA under sedation demonstrated improved detection of apnea episodes and enhanced respiratory safety compared to standard monitoring techniques. Additional research involving more varied populations is necessary to confirm these results.
