Characteristics of lung mechanics in COVID-19 induced ARDS, by Prof. Chun Pan

Prof. Chun Pan, from Critical Medicine of Zhongda Hospital Southeast University, will share about respiratory therapy characteristics of lung mechanics of COVID-19 induced ARDS. According to Prof. Zhong Nanshan's study, about 5% of patients are admitted to ICU, 2.3% underwent invasive mechanical ventilation, and 11.4% died. Mechanical ventilation is the key treatment for patients with severe COVID-19. However, from our clinical analysis, patients had been responded poorly to high PEEP. PEEP is a positive and expiratory pressure. If we increased PEEP at the bedside, we found that patient had either very limited or no improvement in oxygenation, or even deteriorated. Patients also presented a non-proportional increase in driving pressure. So for COVID-19 induced ARDS, there are 4 characteristics of lung mechanics: 1) lower lung recruitability; 2) lower respiratory system compliance; 3) there is no airway closure pressure in the patients; and 4) there is no intrinsic PEEP for the patient.
