According to various embodiments, a medical sensor assembly may be configured to switch between transmission and reflectance mode. Such sensors may include multiple optical sensing components that may be activated or silent, depending on the mode in use. A practitioner may switch between modes based on the particular situation of the patient or based on the signal quality.
