Arm Intervention/treatment
No Intervention: Control
Experimental: Gammacore treatment Device: gammaCore® (Vagus nerve stimulation)
Vagus nerve stimulation using the gammacore neurostimulation device

Primary Outcome Measures :
  1. Incidence of changes in specific clinical events in patients with covid-19. [ Time Frame: From randomization to hospital discharge or ICU admission, whatever occurs first, assessed up to two months ]

    The clinical events include, but are not limited, to:

    • Proportion of subjects requiring mechanical ventilation
    • Days to onset of mechanical ventilation
    • Oxygen support requirements
    • O2 saturation
    • Pain levels
    • PaO2/FiO2
    • Coagulation
    • Laboratory measurements related to circulating cytokines and inflammation.
    • Live discharge from the hospital
    • Patient length of stay
    • Mortality
    • Need for intensive care
    • Shortness of breath
    • Device related serious adverse events
    • Adverse events
