[The clinical application of oxygen saturation pulse oximeter in otolaryngological field].

ABSTRACT

Recently, we had opportunity to use an oxygen saturation pulse oximeter (minolta pulsox-7) which is a compact, light-weight device and allows continuous, percutaneous easy determination of arterial blood oxygen saturation. We obtained the following results from clinical application of this device in the field of otorhinolaryngology. 1. There was a high coefficient of correlation (0.899) between the values of oxygen saturation determined with a Minolta Pulsox-7 and an arterial blood gas analyzer. 2. This instrument was simple to handle and was clinically applicable, and seems to be highly useful for a) timing of tracheostomy, b) objective evaluation of dyspnea, c) monitor of nasal surgery under local anesthesia.
