Preliminary research in the UK has revealed that some people with Covit-19 may have lung effects that are not recognizable on routine exams. The discovery was made by inhaling xenon, which allowed us to see how gas spreads from the lungs to the bloodstream.
The investigation, which now leads to more in-depth work, focuses on the assessment of 11 people who do not require hospital care, but after the infection, the suffocation continued.
Experts at Oxford, Sheffield and Manchester say the finding is one of the most common symptoms of SARS-Cov-2 infection, with shortness of breath lasting several weeks after recovery. This is called a “long cov”, which includes other symptoms that can only be explained by the disease.
The team compared several trials to assess lung capacity in three different groups: those with still shortness of breath and those who have not been admitted to the hospital, those who need to be hospitalized, and those who do not have “long-term goiter” symptoms, and the comparative factor.
They all inhaled xenon during MRI: gas that acts like oxygen, but can be visually monitored during scans. Thus the scientists were able to see how it moved from the lungs to the bloodstream. In most patients with “chronic goiter” disease, gas exchange is less effective than in the healthy model. The same thing happened to those admitted to the hospital.
According to Emily Fraser, the study’s lead researcher, X-rays and CT scans often do not reveal any abnormalities, leaving patients “frustrated” to not be able to explain the exact cause of their shortness of breath. “I hope this will help us to do more research and learn more about the topic,” he stressed.
