Pulse Monitor/Optical Densitometer (Peripheral Blood Flow Coupler)
Product #: V71-40
|
The V71-40 uses a light source and photo-transistor in either the transmissive or reflective mode to measure pulsatile blood flow by optical densitometry. The light is emitted and received by a dual-element emitter and sensor mounted in the transducer head. When used on translucent areas, such as the ear, the light is transmitted completely through the tissue and reflected back by the ear clip. When used where there is underlying bone, the bone itself reflects the light back to the sensor. As opaque blood components flow through the light path, they partially obstruct the beam to generate the signal. The unit may also be used for eye blink and other events producing a pulsatile change in reflectance.
Requires V95-01 pulse transducer. Order separately.
