A.5.5 Sensors
Wavelength
Pulse oximetry sensors contain LEDs that emit red light
at a wavelength of approximately 660 nm and infrared
light at a wavelength of approximately 905 nm.
The total optical output power of the sensor LEDs is less
than 15 mW.
This information may be useful to clinicians, such as
those performing photodynamic therapy.
