In this case report, two COVID-19 patients with acute respiratory distress are presented. In both cases the acute respiratory distress was due to occlusion of the endotracheal tube. Patient A had an occlusion due to a blood clot. Patient B had an occlusion due to mucus secretions. In general, acute obstructions of the endotracheal tube are uncommon. The aim of this case report was to describe unusual complications in intubated COVID-19 patients. The increased risk of acute endotracheal obstruction in COVID-19 patients is due to multiple factors, such as hypercoagulopathy and the duration of the ventilatory support.
