A characterization of motion affecting pulse oximetry in 350 patients.

abstract：:To clarify the effect of hematocrit on the solubility of volatile anesthetics in blood, we measured the blood-gas partition coefficients of isoflurane, enflurane, halothane, and methoxyflurane concurrently at 37 degrees C in blood from four adults. We measured the blood-gas partition coefficients in the plasma (hemato...
