Note: Just below menu item #7 is the example text "VWPro1.0:12-28-10". This indicates the software level. 1. Amp & Sensor: Valsalva Wave "hardware" consists of an "Amplifier" and a plethysmographic "Sensor". The sensor detects blood volume/density as a function of blood flow and pressure. The amplifier amplifies, conditions, and digitizes the signal, as well as providing Universal Serial Bus (USB) interfacing with a Windows PC.
Regarding general use, Valsalva Wave Pro depends on the presence of the Amplifier and Sensor. If the Amplifier is unplugged from the PC when the application is running, the application will be interrupted. Also, if the Sensor is plugged into the Amplifier or unplugged from the Amplifier while the application is running, the application will be interrupted. It is best to plug the Sensor into the Amplifier, then plug the Amplifier into the USB port on the computer, then open the application. Follow this same process in reverse for unplugging the Amplifier and Sensor. Please visit: www.valsalvawave.com/valsalvawavehelp.html for additional information about the Amplifier and Sensor. 2. Sensor Calibration: The Valsalva Wave Pro sensor must properly detect both changes in blood volume and the heart beat. If the sensor is too tight it inhibits changes in blood volume. It if is too loose it doesn't detect the heart beat. To insure proper operation, the pulse wave (top panel) should be consistent and the average Valsalva Wave should be "flat", and not drifting downward. It may take a few minutes for it to flatten as it is dependent on clip pressure, body position, and respiration. Please note that the "drift kit" is required for proper detection and monitoring of simultaneous Valsalva Wave and Heart Rate. View the drift kit discussion below. Click the "Calibrate Sensor" tab on the Navigation Bar to return.
Drift Kit: A "drift kit" (see photo) is normally installed when the ear sensor is shipped. It consists of a small plastic block and a rubber band that secures it to the ear sensor. The block prevents "biological" drift due to continuous squeezing of the ear by the ear clip spring. The block keeps the ear clip blocked open such that it does not squeeze past the point where the sides of the clip are parallel. This solves the drift problem but leads to a looser fit and therefore requires additonal care in attaching it to a part of the ear where it fits well. As long as the sensor picks up the AC Pulsewave signal (see Basic Signals), then it is secure enough. 3. Basic Signals: See description of each graph below.
4. Valsalva Wave Metrics: See description of each graph below. Valsalva Wave signals are "Red".
5. Heart Rate Metrics See description of each graph below. Heart rate signals are "Blue".
6. Thresholds With Release 1.1, Valsalva Wave Pro provides visual thresholding for Valsalva Wave and Heart Rate functions. This includes Valsalva Wave (AC), Valsalva Wave Variability, and Valsalva Wave Variability Average screens. Equivalent thresholding is provided for Heart Rate, Heart Rate Variability, and Heart Rate Variability Average screens. Thresholds are indicated by an adjustable horizontal yellow line that can be moved up or down to indicate the training goal. Audible reward prompts will be added to the visual capability in Release 1.2. A yellow "Threshold" legend is presented at the top of those screens that support thresholding. Also, the "Threshold" button is available on the toolbar. When the threshold button is clicked, the Threshold Settings dialog box appears, allowing the threshold of interest to be selected, and its value established.
Heart Rate Variability screen depicting a threshold set at 20 beats Please note that on variability measurement screens (with a fixed Y-axis) threshold values correlate with the Y axis. On screens where gain is automatically adjusted (and values on the Y-axis vary with gain), threshold values are simply numerical. Also, thresholds are presently not printed on reports. It is recommended that threshold values are recorded using the Event Marker function which is available on recorded reports. Below is an example of a single event marker that captures the threshold for the Heart Rate Variability measurement. Where there is an upper and lower threshold, 2 event markers are presently required.
Recorded "report" depicting Event Marker with threshold value To create an event marker, when in record mode, click the green "marker" on the Control Bar along the bottom of the screen. A small input window will open briefly. Input the threshold value and hit "return". It then appears on reports as depicted above and with exported data.
Using Event Marking to record threshold values 7. Sessions & Reports Valsalva Wave Pro allows the user to run sessions, record session data, and generate reports. Users can access any one of the pre-defined "report screens" or export the data to generate reports externally.
The most basic entry and exit screen To run a session, click on the run session button. Using the primary Navigation Bar at the top of the screen choose the screen you wish to view. To record a session, click on the "record button" depicted in the bottom control bar below. (Valsalva Wave Pro records all of the signals that are being generated by the instrument, not just the one that is presented at any given moment. This allows the user, for example, to record the Valsalva Wave and once the session ends, examine other metrics as they occurred in time, for example Heart Rate.) The yellow bar will begin advancing to the right, indicating that the session is being recorded. To end recording, the record button must be pushed again. Recording stops and the yellow bar disappears. To save the session, click on the "stop" arrow in the lower left corner. (The stop arrow must be pressed to exit any active screen.)
The bottom control bar
When the stop arrow is pressed, the "Save Session Data" dialog box is presented. If it is a new client, click the "New Client" button and complete the form. If it is an existing client, click the drop down arrow to select the client name. Once the name has been selected click "Save To Database". Once saving is complete. click on the "X" in the upper right hand corner of this dialog box to close. This will return the user to the entry screen from which you can run another session, access client data, etc.
The "Saved Signals" field highlighted by the red circle determines what signals the instrument saves during each session. The default setting is "all signals", i.e, all of the check boxes are checked. It is recommended that you do not change the default settings. Note: All screens can be paused and "screen printed" at any time by clicking the "Freeze Screen" icon Valsalva Wave Reports This selection explains the standard reports provided. When a session is recorded, Valsalva Wave Pro records the data associated with any or all signals. Afterwards, the session can be selected and the data can be viewed or exported. The following reports are those automatically generated in Version 1.0. Data is available for all signals for purposes of exporting. Instructions for viewing and generating reports can be found under the Help menu. Valsalva Wave signals are "Red". Heart Rate signals are "blue".
