About

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.

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
  • Child's caregiver is able to communicate using SMS
  • Child has an asthma inhaler

Exclusion criteria

  • Children with complex medical conditions which may hinder their ability to complete protocol assessments
  • Children with an active skin condition involving the area on the chest wall where the Leo device will be attached. E.g. inflamed and/or infected eczema or other skin conditions involving the anterior chest wall at the time of recruitment
  • Children with any implanted medical devices, E.g. cardiac pacemaker
  • Children with any history of known allergic reaction to adhesives or hydrogels, as the ones used with the Leo device

Single Arm - Leo Device Monitoring
Other group
Description:
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.
