Overview

The Test of Incremental Respiratory Endurance (TIRE) protocol is a comprehensive approach to respiratory muscle training that applies proven strength training principles to the breathing muscles. Unlike fixed-resistance devices, TIRE uses variable resistance training that adapts to each individual's capabilities.

The protocol begins with measuring the patient's sustained maximum inspiratory pressure (SMIP) to establish their baseline capacity. Training sessions then consist of six repetitions at 80% of their SMIP, performed once daily. As the patient's respiratory strength improves, the training resistance automatically adjusts to maintain the optimal training stimulus.

This evidence-based approach has been validated through numerous clinical studies showing significant improvements in respiratory muscle strength, endurance, and overall breathing function. The protocol is particularly effective because it provides:

• Progressive overload that matches patient capability
• Precise measurement of respiratory muscle performance
• Objective tracking of improvement over time
• Automated adjustment of training parameters
