PRIMARY outcome

Timeframe: 15-20 minutes from start of the study

Population: The analyses included all participants who completed the study.

Number of participants with collectable waveform data, which corresponds to each breathing exercise from the wearable motion sensor and uploaded to a secured database.

Measure	Healthy Participants n=30 Participants Healthy participants completed a total of approximately 18 measured breaths through a traditional incentive spirometer while wearing small, non-invasive motion sensors taped to the right rib cage.
Participants With Collectable Waveform Data	30 Participants

SECONDARY outcome

Timeframe: Within a month of study completion

Population: The analyses included all participants who completed the study.

Participants with waveform data that support the development and and validation of an algorithm that converts chest-wall motion waveforms into estimated volumes of inspiration. For each participant, motion waveforms is annotated with the corresponding measured inspiratory volumes.
