The document describes the KH2 respiratory muscle training and assessment device. It includes several innovative features such as MIP and PIF test functions that allow practitioners to collect patient data in real-time using the portable KH2 device and Breathe-Link Medic software. The KH2 uses an electronically controlled valve and 'Auto Optimising' technology to adapt training resistance to the user's inspiratory muscle capabilities. Test and training data can be viewed and analyzed at three levels to monitor patient progress and assess respiratory conditions.
