Brief Summary

Objective: To determine whether NIV delivered through helmet interface reduces intubation rate among patients with COVID-19 ARDS compared to face-mask NIV and HFNC. Design, setting \& participants: Two-center randomized clinical trial of 360 patients with mild to moderate ARDS and confirmed COVID-19 requiring non-invasive ventilation between August 2020 to January 2021. The patients with respiratory rate (RR) more than 30/min or oxygen saturation (SpO2) less than 90% or PaO2/FiO2 ratio less than 300 despite standard oxygen therapy by face mask (\<15 L/min) who present to Royal hospital or Sultan Qaboos University Hospital (SQUH) emergency department, medical wards or intensive care unit (ICU). Intervention: Patients will be randomly assigned (block randomization) to either face-mask NIV, HFNC or Helmet NIV. The helmet is a transparent hood that covers the entire head of the patient and has a rubber collar neck seal. Main outcome and measures: The primary outcome is the rate of endotracheal intubation at 28-days. Secondary outcomes include hospital mortality at 28 and 90 days, NIV free days, invasive ventilator free days and hospital length of stay. Expected results: We assume the failure rate of Helmet NIV to be 30%, failure rate of HFNC to be 40% and failure rate of face-mask NIV to be 50%. A sample size of 360 patients (120/group) will achieve a power of 0.90 at a significance level of 0.05. To account for 10% dropout rate, the total sample required is 396 subjects(132/group).

Outcome Measures

Primary Outcomes (1)

  • Rate of endotracheal intubation

    The patient will be randomly assigned to one of the treatment arms. Then the patient will be followed up for one month for the primary outcome which is endotracheal intubation.

    within the study period with an average of one month.

Secondary Outcomes (3)

  • Hospital mortality

    90 days from the hospital mortality.

  • Hospital length of stay

    Throughout the study completion. An average of 90 days.

  • Ventilator free days

    Throughout the study completion. An average of 90 days.
