The long covid is making it difficult for millions of people to return to normal life. However, medical efforts to figure out the best way to help these patients are progressing slowly. However, a Canadian research trial has found an answer to why some people continue to experience symptoms of Covid months after contracting the disease.
According to a Global News report, a team of researchers has focused on a microscopic anomaly in the way oxygen moves from the lungs and blood vessels of long-term patients with Covid-19 in their trial.
The abnormality could explain why some patients feel out of breath and cannot perform strenuous activities after Covid. The study evaluated about 34 patients over about nine months: 12 who had been hospitalized with Covid-19 and 22 more who had not been hospitalized. Patients were still experiencing a number of debilitating symptoms.
The researchers used an MRI technique developed by Western University and found small branches of air tubes in their lungs that were moving into their patients’ red blood cells.
“Red blood cells are responsible for transporting oxygen from the lungs to the rest of the body. Any interruption in the flow of this oxygen to the red blood cells will cause the brain to say ‘breathe more,’ leading to a feeling of lack of ‘breath,’ said lead researcher Grace Parraga.
The 34 patients who participated in the study were experiencing problems with the level of oxygen absorbed by their red blood cells. Therefore, all patients had faced breathing problems.
“All of these patients had this abnormality. They all had really severe symptoms, so their exercise scores were low, they were out of breath when they exercised and when we measured the oxygen levels in the blood at our fingertips afterwards. of the exercise, this was also low, ”the study noted.
The research team acknowledges that the sample size of this study, which has been peer-reviewed, is small and therefore that the results should be considered “exploratory and hypothetical”.
