AirFLO2 Treatment for Hypoxia and/or Tachypnea in Patients With COVID-19
Study Details
Study Description
Brief Summary
The study is an unblinded, randomized, controlled trial for use of the AirFlO2 device for patients admitted to Duke Hospital with COVID-19 and tachypnea (RR >20 breaths/min) and/or hypoxia (Oxygen saturation <94% on room air or requiring supplemental oxygen at baseline).

Detailed Description
The aim of the study is to determine whether the use of the AirFLO2 device can improve hypoxia as measured by change between partial pressure of arterial oxygen to fraction of inspired oxygen- P:F ratio (PaO2:FiO2) and repeat P:F ratio between 1 to 6 hours after using the device.
This is an unblinded, randomized, controlled trial for use of the AirFLO2 device for patients admitted to Duke Hospital with COVID-19 and tachypnea (RR >20 breaths/min) and/or hypoxia (Oxygen saturation <94% on room air or requiring supplemental oxygen at baseline).
Groups will be analyzed by intention to treat. Per-protocol analyses will also be performed. Descriptive statistics will be reported for the overall subject population, and for the two groups.

Active Comparator: Device intervention Intervention participants will receive the AirFLO2 device and training via video with reinforcement from the coordinator how to use and to self-apply it. Clinical data will be recorded before and after intervention. Questionnaires will be completed at baseline and at serial time points after intervention starts. |
Device: AirFLO2

No Intervention: Standard of Care- Control Participants will receive standard of care, clinical data will be recorded. Baseline and end of study questionnaires will be performed. |
Outcome Measures
Primary Outcome Measures
- Improve hypoxia as measured by change between baseline P:F ratio and repeat P:F ratio [change from baseline compared to one to six hours after initial device intervention]
Improve hypoxia as measured by change between baseline P:F ratio and repeat P:F ratio inspired oxygen- P:F ratio (PaO2:FiO2), a higher value indicates better oxygenation. Range 20 to 500.
Secondary Outcome Measures
- Subject dyspnea symptoms [baseline to end of hospitalization, (discharge from hospital or death, 1 - 30 days range)]
Improved symptoms related to dyspnea as measured by the change in the Modified Medical Research Council (MMRC).. Range 0 to 4 with lower values being better.
- Subject cough symptoms [baseline to up to six hours for device intervention participants; baseline to hospital discharge (up to 30 days) for all patients]
Improved symptoms related to cough as measured by the change in Leicester Cough Questionnaire (LCQ) questionnaire, score range 3-21, a higher score indicates better quality of life.
- Subject respiratory symptoms [baseline to up to six hours for device intervention participants; baseline to hospital discharge (up to 30 days) for all patients]
Improve subjective symptoms related to cough as measured by the change in St George Respiratory Questionnaire (SGRC) questionnaire, score range 0-100, a higher score indicates worse quality of life.
- Reduced risk progression of respiratory deterioration [baseline to end of hospitalization, (discharge from hospital or death, 1 - 30 days range)]
Reduce risk of respiratory deterioration as measured by change from baseline to end of hospitalization (discharge or patient death) to high flow nasal cannula (HFNC), non-invasive ventilation (NIV), or invasive ventilation
- Reduced risk of ICU transfer [baseline to end of hospitalization, (discharge from hospital or death, 1 - 30 days range)]
Reduced intensive care unit (ICU) transfer risk, as measured by a change from baseline to end of hospitalization of ICU admission.
- Reduced risk for intubation [baseline to end of hospitalization, (discharge from hospital, or death, 1 - 30 days range)]
Reduce risk for intubation requirement as measured by incidence of intubation occurring between baseline and end of hospitalization (discharge or death)
- Reduced hospitalization length of stay [baseline to end of hospitalization, (discharge from hospital or death, 1 - 30 days range)]
Reduced hospitalization length of stay as measured by length of hospitalization after the baseline timepoint.
- Increased patient survival to discharge [baseline to end of hospitalization, (discharge from hospital- 1 - 30 days expected range)]
Increased patient survival to hospital discharge as measured by the participant status at the end of the hospitalization (discharge or death)
