Trial Parameters
Brief Summary
The aim of this study is to evaluate the predictive role of the Peripheral Perfusion Index (PPI) in forecasting extubation success during the weaning process in intensive care unit (ICU) patients. The study will investigate the ability of PPI to predict extubation failure by comparing it with traditional weaning criteria, including the Rapid Shallow Breathing Index (RSBI), PaO₂/FiO₂ ratio, and respiratory rate.
Eligibility Criteria
Inclusion Criteria: * Patients who have been on mechanical ventilation for at least 48 hours * Patients over 18 years of age who are planned to undergo extubation following a spontaneous breathing trial (SBT) * Patients or their legal representatives who provide informed consent to participate in the study Exclusion Criteria: * Patients for whom extubation is not planned due to hemodynamic instability * Patients with peripheral vascular disease or a history of hand surgery * Patients who die or cannot be followed up during the study period
