BreatheHeart      Tools For Breathing   Valsalva Wave Pro

Valsalva Wave Pro 2.0 Beta Available Now



January 31, 2016


Welcome to Coherence "Valsalva Wave Pro". Valsalva Wave Pro allows us to monitor and train a fundamentally new biometric, the "Valsalva Wave", a breathing induced blood wave that we are able to detect and observe when we are breathing "coherently".

Valsalva Wave Pro also provides monitoring and training of the Heart Rate (Heart Rate Variability Cycle) and the Pulse Wave. You can monitor the Valsalva Wave, the Heart Rate, or the Pulse Wave, either alone or in combination.

This website mirrors the Valsalva Wave instrument. You can think of this page as the "Get Started" page. You can always return to the local page by clicking the "Get Started" tab on the instrument Navigation Bar.

There are 2 instruments, Valsalva Wave Pro and BreatheHeart. Both employ patented technology that provides simultaneous detection of blood volume and heart rate with a single plethysmographic sensor.

"Coherence" is defined as the 180 degree phase synchrony between the heart rate and the blood wave (Valsalva Wave) that elicits it.

About The Instruments:

The Valsalva Wave

Valsalva Wave Pro is designed for researchers, clinicians, and serious health enthusiasts alike. It has sophisticated capabilities required by scientists, multi-client capability needed by clinicians, and "ease of use" desired by all.

At the top left of every screen you will find the "Program Menu" consisting of View, Calibration, Options, and Help. These basic "program" functions are rarely used.

Just below the Program Menu, you will find the "Navigation Bar". It presents buttons that allow you to navigate to the various screens including Get Started, Pulse Wave, Valsalva Wave, Heart Rate (HRV), Signal Checks, and Help.

A toolbar is presented along the far left side of every page. It provides a number of basic functions, allowing us to move the signal up and down, increase and decrease gain, speed up and slow down the graph, zoom in and out, etc. These buttons apply to the signal that we are viewing at the moment. If you mouse over each, the name of the function will appear.

Along the bottom is the Control Bar that includes some very basic functions including start/stop, pause, print, record, freeze view, help, etc. Once a session has been recorded, an option is also presented that allows the data to be stored and reports to be generated. You will want to familiarize yourself with each of these functions.

A quick note about the nomenclature:

Under each tab, you'll find both "stand-alone" and "simultaneous" views. The "+" sign means the first biometric AND the second biometric are presented simultaneously on the same graph, ex. "V-Wave + HRV" means that the Valsalva Wave and the HRV cycle are plotted on a single graph where the Y axis is that of the Valsalva Wave.

Alternatively, "V-Wave, HRV", means that both are visible on the same screen but each is plotted on its own graph with its own Y axis.

The metric that is listed first has precedence, i.e. it assumes the Y-axis or is the top-most graph on a given screen.
