NeXus Blood Volume Pulse Sensor

 

 

 

 

 

 

 

 

 

 

 

The NeXus Blood Volume Pulse (BVP) Sensor is used to measure heart rate and monitor relative blood flow. By using this sensor the Heart Rate Variability (HRV) can be acquired: this refers to the rise and fall of heart rate synchronized with breathing (faster on inhale, slower on the exhale). The magnitude of this systematic variability seems to reflect a healthy alternation between two autonomic influences of the heart beat: sympathetic and parasymphathetic. By calming one's emotional state and by making the breathing slower and more regular, the HRV can be increased, at least temporarily. Use the NeXus Respiration Sensor in combination with the NeXus BVP Sensor in order to monitor both breathing and heart rate.

 
This sensor is usually placed on a finger of the non-dominant hand. Make sure not to move the sensor too much since this will influence your signal and create artifacts/noise.
 
Note: although the BVP sensor is a very efficient way of quickly measuring heart rate you could alternatively do an ECG/EKG with our NeXus EXG sensor. Because of carbon technology and active noise cancellation, this sensor is less susceptible to artifact. The BVP sensor is often preferred though because of ease of use and efficiencThe Blood Volume Pulse (BVP) sensor is used to measure heart rate and monitor relative bloodflow.
