Key points
-
The ACE-2 receptor is important in the pathogenesis of the SARS-CoV-2 virus. Its expression in lung tissue may explain COVID-19 risk especially in patients with prior underlying lung disease.
-
There are a multitude of effects that COVID-19 can have on lungs from ARDS to pneumothoraces. Existing literature, based on randomized controlled trials, supports the use of lung protective low tidal volume ventilation in mechanically ventilated ARDS patients. The optimal amount of PEEP is still disputable.
-
COVID-19 patients are often readmitted with bacterial infections and venous thromboembolism. The long-term effects of COVID-19 can include persistent fibrosis and as a result, many patients remain symptomatic for months after discharge.
