3.2.6 Blood Volume Pulse (BVP)
Figure 51: BVP sensor.
This Blood Volume Pulse (BVP) sensor is an optical, non-invasive sensor that measures
cardiovascular dynamics by detecting changes in the arterial translucency. When the
heart pumps blood the arteries become more opaque, allowing less light to pass from the
emitter on the sensor through to the receiver. The BVP sensor has a plastic clip-on
housing for placement on the finger, which houses the light emitter and detector, and
also minimizes interferences from external light sources.
How to connect your sensor to your biosignalsplux
The blood volume pulse sensor can be connected to any of the available analog inputs
of your biosignalsplux device (see 2.3.2 Analog Inputs)
This sensor does not require an additional reference electrode.
How to configure your sensor in OpenSignals (r)evolution
Open the OpenSignals (r)evolution device manager and select the device you have your
blood volume pulse sensor connected to. Select the channels of your sensor and select
BVP for the channel from of the dropdown menu (click on the arrow in the channel’s field
that appears when you hover over the channel’s field).
Activate this channel for signal acquisition by clicking on the circle in the channel field
(must be blue).
An example configuration is displayed in Figure 52 (here: blood volume pulse sensor
connected to channel 1).
