Overview

This study will be conducted to assess the role of end-tidal carbon dioxide (PETCO2) monitoring to predict the fluid volume responsiveness in correlation with stroke volume variation detected by electrical cardiometry in patients with hemodynamic instability.

Moreover, since PETCO2 is mainly determined by tissue CO2 production (VCO2), alveolar ventilation and CO, when stable metabolic conditions are assumed and minute ventilation is kept constant, acute changes in PETCO2 have been shown to correlate strongly with changes in CO. Thus, PETCO2 has been suggested as a simple economic and noninvasive alternative for continuous assessment of CO in different shock states.
