Scientists from the University of Western Ontario in Canada have studied the mechanisms of long-term symptoms

During the experiments, participants inhaled xenongas, thanks to which experts were able to monitor in real time how the alveolar sacs, which are responsible for delivering oxygen to the blood, work.
In the process, the work of 300-500 million alveolar sacs was studied, which made it possible to see how oxygen supply to red blood cells is disturbed in patients with coronavirus.
Based on the new data, scientists wantadjust existing anti-COVID therapies, and help shorten the duration of COVID-19 symptoms such as shortness of breath, blurred consciousness, and fatigue.
