The PrO2Health Connected Platform aligns with skeletal muscle training tenets. This includes overload and specificity with the default setting of high-intensity loading within an incremental regime based on each training day one rep max (baseline breath). The load and unique assessments are through a full range of contractions from residual volume (RV) to total lung capacity (TLC). This includes standard maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) as isotonic pressure measures that indicate respiratory muscle strength.

PrO2Health developed the new sustained maximum inspiratory pressure (SMIP) many years ago. This isokinetic pressure curve looks at work per breath and power output (from pressure) based on a maximal effort from RV to TLC. The SMIP utility has been identified in several references, underscoring the effectiveness of the PrO2Health Connected Platform.

In the Test of Incremental Respiratory Endurance (TIRE), the SMIP is reduced to 80% of individual capacity (with a 10% leeway), and training is then done within a progressive regime based on the time between breaths being reduced every six breaths until failure or 36 breaths (with the option of bonus breaths). Thus, exercise is taken to pre-fatigue or fatigue when the training stops. This is always based on individual capacity, fulfilling the concepts of overload and specificity.

Unlike many IMT regimes, the PrO2 training schedule is designed for practicality and effectiveness. It involves training three times a week in the short to medium term and then one to two times weekly for maintenance. This approach ensures that reversibility is less of a concern than with regimes that require daily IMT, providing reassurance about the PrO2 device's convenience and effectiveness.

PrO2Health developed and patented the Fatigue Index Test (FIT) score. This measures capacity versus demand for the inspiratory muscles and is based on power output to move a standard tidal volume (V/T) ratio of 500 milliliters (mL). Against total resisted inspiratory vital capacity (IVC) over time to move the tidal volume against IVC time. This divides a fraction into 1 to give an equivalent of the whole number where higher is better. Compromised patients have scores in low single figures, whereas some athletes score > 100. This is further divided into segments of the SMIP so that we have work and FIT equivalents of forced expiratory flow (FEF) divisions. Still, FIT values reflect the power and flow generated by inspiration.

The PrO2Health Connected Platform represents a significant advancement in respiratory muscle training, aligning with established principles of overload and specificity. By combining innovative tools like the sustained maximum inspiratory pressure (SMIP) and the Fatigue Index Test (FIT), the platform offers a practical, evidence-based approach to improving respiratory muscle strength and endurance. Its emphasis on individualized training regimens ensures that users can achieve optimal results conveniently and efficiently, making it a valuable asset for athletes and those with compromised respiratory function.
