It is likely that multiple technicians will be asked to perform 6MWTs on patients. Without a strict, standardized protocol, each technician could slightly vary how they run the test, what commands they give the patient, and the parameters they record, all of which can lead to variable data that delivers less-accurate data trends.Vyntus™ WALK is standardized to run the recommended American Thoracic Society (ATS) 6MWT protocol, because accurate comparison requires consistent testing that yields consistent data.
 

One of the cardinal rules of a good 6MWT is to have the patient walk of their own volition. But if the patient is tethered to the technician by a pulse oximeter cable, and the technician is walking just behind the patient, the patient's performance can be directly influenced or affected. Vyntus™ WALK uses Bluetooth™ wireless pulse oximeter technology that allows the patient to move through the entire course and limits technician influence. Also, the sensor provides a more complete HR and SpO₂ reading over time.

Not every clinician prefers to view data the same way. That's why with Vyntus™ WALK, you first see the data as its being collected graphically over time. But with a simple finger swipe, you can switch to the Easy-View mode, displaying large numeric values for HR and SpO₂. Swipe back, and you are back to viewing graphically over time. And if the patient needs to pause, Vyntus™ WALK will continue to show both active HR and SpO₂ values throughout the pause time screen.

Vyntus™ WALK can be run as a standalone device generating a standard report, or the data can move in and out of SentrySuite™ software for a more robust interpretation and trending report.

As a standalone device, users quickly enter patient demographics directly on the tablet PC, run the 6MWT, and print a standard report using one of two options:

• Print standard reports using WiFi direct to a printer or print via USB cable to a printer
• Store standard report on a network share drive as a PDF

As a device connected to SentrySuite™, users receive demographics from SentrySuite™, run the 6MWT, and then return completed test data to SentrySuite™.  From SentrySuite™, more options are available:

• Connect with WiFi or USB tethering
• Review data and add technician and physician comments
• Trend data with past patient visits (also useful for treatment efficacy)
• Combine reporting with other tests, such as spirometry or diffusion testing
• Move data to the EMR
