analyzeBreathShape

Analyzes flow-volume shape characteristics including peak flows, symmetry, concavity, and detection of flow limitations or irregularities

This function receives as an input raw flow data and breath indices from any metabolic cart, flowmeter, or pneumotach, and extracts key features from individual breath shapes. Variables such as peak flows, symmetry, concavity, and irregularities are visualized and quanitified against evidence-based thresholds.

Can receive data type timetable or a scalar struct as input, such that a continuous workout (i.e., CPET) or intervals (i.e., HIIT) can be analyzed.

Not yet citable. To be presented at 2026 European Respiratory Society congress.
