SIGNIFICANCE OF TISSUE OXYGENIZATION IN PATIENTS CONNECTED TO A MECHANICAL VENTILATOR

Abstract

Aim The aim of this study is to investigate whether the follow-up of patients on a mechanical ventilator using a tissue oxygenation device is superior to that using an O2 saturation probe. Method Our study was conducted at the Necmettin Erbakan University Meram Medical School Emergency Medicine Critical Care Unit between 01/04/2016 and 01/06/2016. Patients over the age of 18, non-pregnant, and followed up on mechanical ventilators were prospectively recruited, and the saturations of the patients with tissue oxygenation devices and pulse oximetry were evaluated and compared. SPSS (ver. 19.0) was used for the statistical analysis of the collected data, and the descriptive measures of all the obtained variables were calculated. Results The collected data revealed a statistically significant positive correlation between oxygen saturation measured by pulse oximetry and tissue oxygen saturation (StO2) in the patient group (n = 53), in which deceased and discharged patients were evaluated together. Both the hemoglobin levels and StO2 were low in the sepsis patients. Conclusion It is important to follow tissue perfusion in intensive care patients, and this can be done with a noninvasive method. The results of our study reveal that perfusion should be followed with tissue oxygenation in patients on mechanical ventilators because low tissue oxygenation indicates increased patient mortality.
