Clinical Trial Summary

This is an early phase pilot study designed to test the safety and feasibility of using a novel, wireless, wearable device (Leo) for assessing respiratory parameters (lung volume, respiration rate, heart rate and indices related to tidal breathing flow volume loop) in children with respiratory condition (such as asthma). There is no product currently on the market that is comparable to this novel Leo device The study consists of a single visit to evaluate the feasibility and safety of using the Leo device on 20 children with clinically stable asthma. Stable asthmatic children between the age of 3 and 6, inclusive, will be recruited. There will be no disease-specific intervention, nor changes to the participant's care management program for their asthma.

Eligibility

Inclusion Criteria:

• Children aged =3 years old and =18 years old at time of consent
• Children with a legal guardian able to sign consent for study participation
• Children and caregivers able to read and understand English or Spanish
• Investigator confirmation for diagnosis of clinically stable respiratory condition, such as clinically diagnosed asthma

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Slow vital capacity from Leo device	Agreement and correlation in the lung function parameters derived using the respiratory impedance signals recorded from Leo device, compared to the pneumotachograph (PNT) device. The PNT device readings will be considered the standard of care, and compared against the Leo device to evaluate for device feasibility. This will be done before and after administration of bronchodilator.	Baseline
