Acute respiratory distress syndrome
Acute respiratory distress syndrome (ARDS) is a complication of Covid-19. This syndrome occurs when a person's lungs are severely damaged by viral attacks, causing fluid to accumulate in the air sacs, which prevents oxygen from entering the blood and the rest of the body, thereby leading to a condition known as: respiratory failure and even death if the patient is not treated promptly.
Because ARDS symptoms are not specific, the diagnosis can only be based on the following factors: rapidly increasing dyspnea, cyanosis of the lips, extremities; poor response to oxygen therapy; diffuse bilateral and progressive alveolar lesions (can be determined by chest X-ray); hypoxemia PaO2/FiO2 ≤ 300 mmHg with PEEP ≥ 5 cmH2O. Because the disease symptoms are not specific, doctors need to determine based on the patient's medical history, combined with a physical examination to make a differential diagnosis with other respiratory diseases, thereby determining the method of treatment. optimal treatment for the patient.
If not treated promptly, acute respiratory failure can be fatal. According to the American Thoracic Society, the annual rate of ARDS in this country is 360,000 cases, of which 36% die during the hospital stay. Depending on the cause of ARDS, this number can be higher. Treatment of ARDS is extremely difficult, patients have to carry oxygen machines with them wherever they go or even have to undergo tracheostomy to support breathing in some cases.
