Abstract
An alignment guide system for use with conventional pulse oximetry monitors connected to transmissive pulse oximetry sensors. The system generates a bar graph or other display showing the magnitude of the optical coupling between the LED's and light detector used in the sensor. By manipulating the position of the sensor while observing the bar graph, medical practitioners can optimize the mount of light from the LED's reaching the light detector. The bar graph also contains an alarm limit marker. If the bar graph falls below the alarm limit marker, the entire bar graph flashes to alert the medical practitioner that the mount of light transmitted to the LED's to the light detector may not be enough to permit sufficiently accurate oxygen saturation measurements.
