Understand the Problem
The image appears to contain detailed notes about pulse oximetry, including its measurement principles, applications, limitations, and types of sensors. The user may be seeking clarity or further information on specific aspects of pulse oximetry or related medical concepts.
Answer
Pulse oximetry measures oxygen saturation using spectrophotometry and photoplethysmography.
Pulse oximetry uses spectrophotometry and photoplethysmography to measure blood oxygen saturation and heart rate non-invasively. It works by shining light through tissue and measuring absorption at different wavelengths. Applications include monitoring oxygen levels during surgery and in critical care settings.
