Open Access Abstract Introduction The study sought to assess the feasibility and accuracy of measuring mixed venous oxygen saturation SvO2 through the left main bronchus SpO2trachea Methods Twenty hybrid pigs of each sex were studied. After anesthesia a Robertshaw double-lumen tracheal tube with a single-use pediatric pulse oximeter attached to the left lateral surface was introduced toward the left main bronchus of the pig by means of a fibrobronchoscope. Measurements of SpO2trachea and oxygen saturation from pulmonary artery samples SvO2blood were performed with an intracuff pressure of 0 to 60 cmH2O. After equilibration hemorrhagic shock was induced in these pigs by bleeding to a mean arterial blood pressure of 40 mmHg. With the intracuff pressure maintained at 60 cmH2O SpO2trachea and SvO2blood were obtained respectively during the .
