Brief Summary:
Existing information suggests that a drug called heparin, given through a device called a nebuliser, will decrease severity of lung damage caused by COVID-19 who require the assistance of a ventilator to breathe. It is thought that heparin could do this through multiple mechanisms. The investigators will measure the effect with a marker called d-dimer, which is related to blood clotting, and monitor the safety of this treatment as one of the major outcomes for the study. The investigators will also assess clinical outcomes such as markers of oxygen levels, time to liberation from a ventilator in patients with COVID-19 lung disease, and functional outcomes at day 28 and 60 as secondary outcomes.

Primary Outcome Measures :
  1. D-dimer profile [ Time Frame: Up to day 10. ]
    Effect of nebulised heparin on d-dimer profile, assessed via d-dimer AUC and via a mixed effects model, with data collected on days 1, 3, 5 and 10.

  2. Frequenccy of Severe Adverse Outcomes [ Time Frame: Up to day 60 ]
    Safety of nebulised heparin delivered by aerogen solo nebuliser in patients with COVID-19 induced severe respiratory failure, as measured by the incidence of severe adverse events.


Secondary Outcome Measures :
  1. Oxygenation Index [ Time Frame: Up to day 10 ]
    Determine the impact of nebulised heparin on oxygenation index

  2. Indices of Inflammation [ Time Frame: Up to day 10 ]
    Effect of nebulised heparin on indices of inflammation (Interleukin (IL)-1β, IL-6, IL-8, IL-10 and soluble TNF receptor 1 (sTNFR1), C-reactive protein, procalcitonin, Ferritin,) will be assessed (AUC on days 1, 3, 5 and 10)

  3. Ratios of Indices of Inflammation [ Time Frame: Up to day 10 ]
    Effect of nebulised heparin on the ratios of IL-1β/IL-10 and IL-6/IL-10 will also be assessed.

  4. Indices of Coagulation [ Time Frame: Up to day 10 ]
    Effect of nebulised heparin on other indices of coagulation (Fibrinogen; lactate dehydrogenase) will be assessed (AUC on days 1, 3, 5 and 10).

  5. Quasi-Static Lung Compliance [ Time Frame: Up to day 10 ]
    Determine the effect of nebulised heparin on Quasi-Static Lung Compliance (i.e. tidal volume/(Plateau pressure-PEEP) measured on days 1,3,5,10.

  6. Time to separation from invasive ventilation [ Time Frame: Up to day 28 ]
    Time to separation from invasive ventilation, where non survivors are treated as though not separated from invasive ventilation.

  7. Number treated with neuromuscular blockers [ Time Frame: Up to day 10 ]
    Number treated with neuromuscular blockers instituted after enrolment

  8. Number treated with Prone positioning [ Time Frame: Up to day 10 ]
    Number treated with prone positioning instituted after enrolment

  9. Number treated with extra-corporeal membrane oxygenation [ Time Frame: Up to day 10 ]
    Number treated with extra-corporeal membrane oxygenation instituted after enrolment

  10. Number requiring Tracheostomy [ Time Frame: Up to day 28 ]
    Number tracheotomised

  11. Time to separation from invasive ventilation among survivors [ Time Frame: Up to day 28 ]
    Time to separation from invasive ventilation among survivors

  12. Discharge to ward [ Time Frame: Up to day 28 ]
    Time to separation from the ICU to day 28, where non-survivors to day 28 are treated as though not separated from invasive care

  13. Discharge to ward in survivors [ Time Frame: Up to day 28 ]
    Time to discharge from the ICU to day 28, among survivors

  14. Patient Survival [ Time Frame: Up to day 60 ]
    Survival to day 28; Survival to day 60; and Survival to hospital discharge, censored at day 60

  15. Number of patients residing at home or in a community setting at day 60 [ Time Frame: Up to day 60 ]
    Number residing at home or in a community setting at day 60

  16. Number of surviving patients residing at home or in a community [ Time Frame: Up to day 60 ]
    Number residing at home or in a community setting at day 60, among survivors
