Sustained Impairment in Cardiopulmonary Exercise Capacity Testing in Patients after COVID-19: A Single Center Experience

<div>Representative 9-panel display of Wasserman of a limited post-COVID-19 patient. V’E: respiratory minute volume, HR: heart rate, O<sub>2</sub>/HR: oxygen pulse, V’O<sub>2</sub>: oxygen uptake capacity, V’CO<sub>2</sub>: carbon dioxide elimination capacity/carbon dioxide output, EqO<sub>2</sub>: oxygen ventilatory equivalents, EqCO<sub>2</sub>: carbon dioxide ventilatory equivalents, VTex: expiratory tidal volume, RER: respiratory exchange rate, BR: breathing reserve, PETO<sub>2</sub>: end-tidal partial pressure of oxygen, PETCO<sub>2</sub>: end-tidal partial pressure of carbon dioxide, PaO<sub>2</sub>: arterial/arterialized capillary oxygen partial pressure, and PaCO<sub>2</sub>: arterial/arterialized capillary carbon dioxide partial pressure.</div>
