Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, observational study to investigate the agreement of the Leo device signal derivation with gold standard asthmatic testing in recently exacerbated asthmatic children.

This study is designed for engineering validation of a wireless, wearable device (Leo) for assessing clinical control of children recovering from acute respiratory event such as asthma attack. The Leo device will monitor chest impedance, ECG and body position to calculate parameters such as respiration rate, heart rate, lung volume, tidal breathing flow and volume curves, and body position. These parameters will then be used to train and algorithm to assess clinical control of asthma.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Single Arm - Leo Device Monitoring

Child's respiratory impedance will be continuously recorded using the Leo device during hospital/ED stay after consent and enrollment, and then during 7 days at home after discharge. The Leo device provides no intervention, and will only monitoring chest impedance for the worn period. Oscillometry and spirometry testing and flow volume assessment using PNT will be performed during study visits with Leo device attached.

Group Type OTHER

Leo device monitoring

Intervention Type DEVICE

After consent and enrollment, the child's respiratory impedance will be continuously recorded using the Leo device throughout the day and night during the entire hospital stay or ED visit. The device may be taken off for up to 1 hour per day (i.e., break during bath / shower time). The device will be applied to the skin overlying the mid-sternum area on the chest wall after cleaning of the skin with an alcohol swab after consent has been obtained. The device will be changed every 72 hours or earlier, by the participant's guardian, depending on signs of defect in the signal quality or battery exhaustion, based on daily check of the signal by the research team. Remote monitoring of the child's chest impedance will continue using the Leo device after discharge from hospital/ED for 7 days.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Children aged ≥2 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
* Children who are currently hospitalized with acute exacerbation of asthma
