Ian Hall, professor of molecular medicine at the University of Nottingham who is not involved in the projects, explained to:"Nitric oxide works mainly by relaxing the blood vessels which supply blood to the lungs from the heart, and has been used to treat patients with other conditions where the pressure in these blood vessels is too high.
It is hoped the treatment would reduce the number of patients who need treatment in an intensive care unit or a ventilator, said Hall. However, he stressed"whilst there is some anecdotal evidence this may work in patients with COVID19, there has been no formal clinical trial to date.""Hence I think it is critical that these interventions are studied in a formal clinical trial setting. As such it is encouraging to see that this is exactly the approach being suggested in these studies," he said.
