Abstract

Objective: To describe the correlation between indices measured by non-invasive blood gas  (AGM100 MediPines) and arterial blood gas (ABG). Participants: Patients age ≥18 years with hypoxemic respiratory failure treated with invasive mechanical ventilation at the Center for Critical Care Medicine, Bach Mai Hospital. Methods: A prospective descriptive study was conducted on patients with hypoxemic respiratory failure treated with invasive mechanical ventilation. Key parameters such as SpO₂, gPaO₂, gPaO₂/FiO₂, PETCO₂, and O₂ Deficit were measured using the AGM100 MediPines. PaO₂, PaO₂/FiO₂, PaCO₂, and A-aDO₂ were measured using the arterial blood gas. Results: There were 33 patients included in the study with total of 165 non-invasive blood gas measurements and 165 arterial blood gas measurements. There was a good correlation between the non-invasive indices and ABG measurements, with R² ranging from 0.47 to 0.89. Notably, the O2 Deficit and A-aDO2 had the highest correlation coefficient (R² = 0.89). However, some indices, such as PaO2/FiO2, exhibited a high mean deviation, indicating significant difference between the two measurement methods. Conclusions: The AGM100 MediPines device may serve as a useful supplementary tool in monitoring non-invasive respiratory indices, minimizing risk and discomfort for patients.
