Abstract

Resident, Department of Anesthesiology, Box 238, Health Sciences Center, University of Virginia, Charlottesville, Virginia 22908.In Reply:--I appreciate the interest of Butler and Kenny in our method of preoxygenation. [1]We did not intend to imply that this method alone would achieve an optimal alveolar oxygen fraction. However, in patients who refuse placement of a mask on their face, the method we describe is superior to no preoxygenation.Robert B.
