Non-Invasive Monitoring of Respiratory Function in Spontaneously Breathing Patients With COVID-19 Infection

This study uses the AirGo band to monitor changes in tidal ventilation in spontaneously breathing patients with COVID-19 associated respiratory failure. It aims to recognize patterns of ventilation associated with worsening respiratory failure in this patient population. If successful, this study will lead to the development of new robust methods for real-time, continuous monitoring of respiratory function in patients with respiratory failure. In turn, such monitoring methods may enable improvements in the medical management of respiratory failure and timing of interventions.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Endotracheal intubation during present hospitalization, recorded through chart review	Progression of respiratory failure to require endotracheal intubation (and mechanical ventilation)	Up to three weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Improvement in hypoxemia as indicated by oxygen saturation and requirement for supplemental oxygen, recorded through chart review	Maintenance of SpO2 >=90% on no or low flow supplemental oxygen (=< 1 liter by nasal cannula or CPAP, or return of supplemental oxygen to baseline if required supplemental O2 for another indication, prior to onset of COVID-19 infection)	Up to three weeks
Premature need for removal of the band, recorded through investigator report	Patient or care provider may request removal of the band for any reason prior to the patient reaching the outcome	Up to three weeks
In-hospital mortality, recorded through chart review	Death from any cause while in the hospital	Up to 24 weeks
