question 6

Multiple Choice

How is the percentage of functional hemoglobin that is saturated with oxygen determined via pulse oximetry?

• A) The percentage of red light that lands on the photodiode represents the SpO₂ (oxygen saturation as determined by pulse oximetry).
• B) The percentage of infrared light that reaches the photodetector reflects the SpO₂.
• C) The ratio of the red and infrared light that reaches the photodiode signifies the SpO₂.
• D) The sum of the amount of red and infrared absorbed by the tissue determines the SpO₂.
