title: Usefulness of a pulse oximeter for enhancing breath holding in hepatic subtraction angiography.
abstract: This study examined the usefulness of a pulse oximeter in hepatic digital subtraction angiography (DSA) with oxygen administration for breath holding. Oxygen saturation and dissociation times were measured using a pulse oximeter. Twenty-eight patients inhaled oxygen at a rate of 3 liters/min through a nasal tube. Saturation times ranged from 0 to 140 seconds to achieve arterial oxygen-hemoglobin saturation of almost 100%. Dissociation times ranged from 0 to 600 seconds after oxygen termination.
