Photoplethysmography (PPG) is the process of applying a light source and light sensor to an appendage, such as a finger or a tow, and measuring the light that is reflected by the skin. At each contraction of the heart, blood is forced through the peripheral vessels producing engorgement of the vessels under the light source, there by modifying the amount of light reflected to the photo sensor. Since vasomotor activity is controlled by th sympathetic Nervous System (SNS), the Blood Volume Pulse (BVP) measurements can display changes in sympathetic arousal. An increase in BVP amplitude indicates decreased sympathetic arousal and greater blood flow to the peripheral vessels.
Using the Velcro strap, fasten the sensor enclosure to the pad of a finger. Make sure the placement you are using is clear of any scar tissue, abrasions or anything that might impede a light source form penetrating through the tissue. Make sure both openings on the enclosure are covered by the placement. Any outside light allowed to get under the enclosure will cause artifact and readings that will be suspect.Used equipment is not always in stock.
