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 SpO<jats:sub>2trachea<\/jats:sub> and oxygen saturation from pulmonary artery samples (SvO<jats:sub>2blood<\/jats:sub>) were performed with an intracuff pressure of 0 to 60 cmH<jats:sub>2<\/jats:sub>O. 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 cmH<jats:sub>2<\/jats:sub>O, SpO<jats:sub>2trachea<\/jats:sub> and SvO<jats:sub>2blood<\/jats:sub> were obtained respectively during the pre-shock period, immediately after the onset of shock, 15 and 30 minutes after shock, and 15, 30, and 60 minutes after resuscitation.<\/jats:p>\n                     <\/jats:sec><jats:sec>\n                        <jats:title>Results<\/jats:title>\n                        <jats:p>SpO<jats:sub>2trachea<\/jats:sub> was the same as SvO<jats:sub>2blood<\/jats:sub> at an intracuff pressure of 10, 20, 40, and 60 cmH<jats:sub>2<\/jats:sub>O, but was reduced when the intracuff pressure was zero (<jats:italic>p<\/jats:italic> &lt; 0.001 compared with SvO<jats:sub>2blood<\/jats:sub>) in hemodynamically stable states. Changes of SpO<jats:sub>2trachea<\/jats:sub> and SvO<jats:sub>2blood<\/jats:sub> corresponded with varieties of cardiac output during the hemorrhagic shock period. There was a significant correlation between the two methods at different time points.<\/jats:p>\n                     <\/jats:sec><jats:sec>\n                        <jats:title>Conclusion<\/jats:title>\n                        <jats:p>Measurement of the left main bronchus SpO<jats:sub>2<\/jats:sub> is feasible and provides similar readings to SvO<jats:sub>2blood<\/jats:sub> in hemodynamically stable or in low saturation states.
