PULSE OXIMETRY METHODS AND APPARATUS FOR USE WITHIN AN AUDITORY CANAL |
摘要 |
<p>Methods and apparatus for detecting oxygen saturation levels in blood from within an auditory canal of a living being proximal to a tympanic membrane are disclosed. The auditory canal is lined with tissue and includes a proximal bend and a distal bend located between the proximal bend and the tympanic membrane. Oxygen levels are detected by emitting one or more wavelengths of light into a first position on the tissue of the auditory canal in a first region defined by the distal bend and the tympanic membrane. The wavelengths of light are then sensed at a second position on the tissue of the auditory canal in the first region. A blood oxygen saturation level and/or pulse rate is then calculated responsive to intensity information corresponding to the wavelengths of light detected at the second position.</p> |
