ORI and ETCO₂ Relationship With Arterial Blood Gas During Apnea Test

Turkey (Türkiye)35 participantsStarted 2023-07-01

Plain-language summary

This observational study aims to evaluate the relationship between the Oxygen Reserve Index (ORI) and End-Tidal Carbon Dioxide (ETCO2) values with arterial blood gas parameters in patients undergoing the apnea test for the diagnosis of brain death. The study will examine the correlation between ORI and PaO2, as well as between ETCO2 and PaCO2. The primary objective is to assess the effectiveness of ORI in evaluating oxygenation and its applicability in the apnea test. The study will also evaluate the routine use of ORI in monitoring PaO2 and its potential benefits compared to traditional methods.

Inclusion Criteria: * Patients who meet all the prerequisites for initiating the brain death diagnosis process and for whom the decision to perform the apnea test for diagnosis of brain death. * Patients aged 18 years or older. * Patients who have provided verbal and written consent from their first-degree relatives. Exclusion Criteria: * Patients whose first-degree relatives do not consent to participation in the study. * Patients in whom the ORI probe cannot be used due to circulatory disturbances in the extremities
