Oxygen saturation in eighty-two patients having elective urologic and gynecologic procedures in the lithotomy position using spinal anesthesia was studied to determine if clinically significant changes of oxygen saturation occurred during these procedures. The oxygen saturation was measured using the pulse oximeter and recorded on a paper chart recorder. Forty-eight patients sustained a normal oxygen saturation throughout the procedure. Twenty-one patients showed a trend of falling oxygen saturation of 3.4% (range: 2-6%). Fourteen patients had transient changes of less than 2-minute durations with falls in oxygen saturation averaging 6.4% (range: 2-14%). Minor artifacts in the oxygen saturat..
