Vyntus Walk is a mobile medical application which is intended to be used on a mobile platform to collect and collate sequential pulse oximetry data during six minute walk tests (6MWT). Pulse oximetry data are collected from an external pulse oximeter, using Bluetooth connection. The mobile platform has access to a host computer with SQL database (SentrySuite) via a wireless network for further data evaluation and diagnosis. Patients as young as 4 years of age and older can be tested providing they can cooperate with the test instructions. Measurements are performed under the direction of a physician in a hospital environment, physician’s office or similar setting (professional healthcare facilities).
