This research study only enrolls hospitalized patients at Penn Medicine.
The purpose of the study is to assess differences in respiratory and ventilation parameters between HFNC and helmet CPAP in obese patients with COVID-19 AHRF. We will enroll patients admitted to a HUP ICU with COVID-19 who have an obese BMI and are receiving HFNC. Patients will be monitored with electrical impedance tomography (EIT) in addition to standard ICU monitors. Patients will receive alternating treatment with HFNC and helmet CPAP over a 90 minute study period.
