According to PGS Phuong, the cause of post-COVID-19 syndrome is a virus SARS-CoV-2 causes inflammatory reactions – cytokines – fibrosis – coagulation disorders.

Among the post-COVID-19 problems that F0 may face, Associate Professor Phuong pays particular attention to pulmonary fibrosis and pulmonary embolism. “These are the two most obvious and severe pulmonary sequelae of the post-COVID-19 syndrome with respiratory manifestations usually mild to severe dyspnea; persistent cough, chest pain; decreased respiratory function”, warns Associate Professor Phuong.

Pulmonary fibrosis

According to PGS Phuong, groups at high risk of developing pulmonary fibrosis after COVID-19 include: Older people, men, length of hospital stay; Pre-existing comorbidity or interstitial lung disease; critically ill patients.

Most patients with the disorder will have respiratory symptoms (dyspnea, cough) and impaired respiratory function. It should be noted that the risk of pulmonary fibrosis after COVID-19 in patients 4 weeks after being infected with COVID-19 still has the following conditions: Tachypnea, cough, chest tightness, hypoxemia (SpO2 < 95%).

Pulmonary embolism

Pulmonary embolism is a common complication in patients with severe or moderate COVID-19 disease. Acute pulmonary embolism can also turn into mild cases of COVID-19 and occur late in the course of the disease. To diagnose this disease, it is necessary to rely on the results of the high blood D-Dimer test, accompanied by signs of pulmonary hypertension, which is diagnosed by CT imaging of the lungs with contrast.

Associate Professor Phuong said that in order to address this issue, it is very important to restore respiratory function early for patients with post-COVID-19 pulmonary fibrosis. The combination of rehabilitation exercises, combined with medication under the guidance of a doctor will help patients recover more quickly.

However, for patients with lung damage, especially those with pulmonary fibrosis, it is necessary to immediately treat and treat them,” said dr.

Doctor Dan suggested, after recovering from his illness, suspected lung damage should be tested first by measuring SpO2 with a finger. Thus, the patient lies on his back in bed for a few minutes, breathes fresh air and measures with his nails (without nail polish), if the SpO2 is less than or equal to 94%, while the body is not nervous and the hands are not cold, they should come to the hospital. hospital to monitor the sequelae of COVID-19.

Besides that, you can try taking stairs, for example, usually if the patient can climb 5 stairs before infection, but after being infected with COVID-19, he can only go up 3 floors, it is also recommended to see a doctor. .
