A mixed-methods study will be used to evaluate the use of standard of care periodic pulse oximetry by parents/LAR and the feasibility of the collection of physiologic data related to the use of the Pediarity System. This system includes the Gabi Band and software platform (Gabi Analytics).

After enrollment, parents will be taught by the study team on the use of the Pediarity System which includes the placement of the Gabi Band and the use of the Gabi Wi-Fi monitor application for data transfer. This education by the study team will ensure uniform training and preliminary understanding with teach back on the use of the Gabi band and Gabi Wi-Fi monitoring application. Parents can ask the study team any use and/or technical questions during this time period. All clinical care questions from standard of care monitoring will go to the CHAMP healthcare team. If parents/LARs have a clinical concern from a value on the Pediarity System - they will be referred to use their standard of care pulse oximetry before any clinical intervention and care is recommended by the healthcare team. The study team will not make any healthcare or diagnostic recommendations during the monitoring period based on any Pediarity System data.

The study team will educate parents and LARs on the Pediarity System. This system does not replace any use of their standard of care pulse oximetry and CHAMP videos. Parents may place the Gabi band on their child and use the Pediarity System at any frequency they choose in the home setting for a length of approximately one month at home (to coordinate when they return to the study site for a care visit). Parents can email or Teams call the study team directly (during daytime hours M-F) for any technical questions during this the study period. The study team will evaluate clinical data only at the conclusion of the study period and qualitative feedback from the parents will be gathered.
