Awake extracorporeal membrane oxygenation support for a critically ill COVID-19 patient: A case report

Figure 1 Chest X-ray images of a 53-year-old man with coronavirus disease 2019 at four time points. A: Chest X-ray at admission; B: Chest X-ray after tracheal intubation; C: Chest X-ray after 96 h of mechanical ventilation; D: Chest X-ray after establishing extracorporeal membrane oxygenation.

Figure 2 Chest computed tomography at three time points. Two representative slices of the middle and lower lobe were chosen. A: 48 h of extracorporeal membrane oxygenation; B: 1 wk of extracorporeal membrane oxygenation and prone position ventilation; C: 5 d of awake extracorporeal membrane oxygenation and rehabilitation.

Figure 3 Changes in pressure of oxygen/fraction of inspiration O₂ and pressure of carbon dioxide/compliance over time. T1: Admission; T2: After 24 h of non-invasive ventilation; T3: Intensive care unit admission; T4: Before intubation; T5: After 24 h of intubation; T6: 24 h before extracorporeal membrane oxygenation (ECMO) was established; T7: Before ECMO weaning (ECMO oxygen concentration was 21%); T8: 24 h after ECMO weaning; T9: Before MV weaning; T10: 24 h after MV weaning. PaO₂/FiO₂: Pressure of oxygen/fraction of inspiration O₂; PCO₂: Pressure of carbon dioxide; MV: Mechanical ventilation.
