Leo Study Unstable Asthma
Engineering Validation of Leo Device to Assess Clinical Control of Children Recovering From Acute Asthma Exacerbation
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.

다른: 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.
|
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.

Airway resistance through oscillometry test
기간: Baseline visit and 7 days post hospital/ED discharge
|
Asthma severity measures will be determined through oscillometry test at baseline and follow-up visit.
Leo measurements will be assessed for agreement with oscillometry measures.
|
Baseline visit and 7 days post hospital/ED discharge

Asthma Flare-up diary
기간: Follow-up for 7 days post hospital/ED discharge
|
Self-reported asthma flare-up diary score will be measured daily during the remote (at home) period in between visits.

Follow-up for 7 days post hospital/ED discharge
|
|
CASI questionnaire
기간: Baseline visit and 7 days post hospital/ED discharge
|
Questionnaire will be used to determine asthma severity during baseline and follow-up visit.
CASI scores include five domains: day symptoms and albuterol use, night symptoms and albuterol use, controller treatment, lung function measures, and exacerbations.
Range is from 0 -17, with a higher score indicating worse asthma severity
