Abstract Reflections on the ventilatory equivalent of carbon dioxide (VE/VCO2) and its slope VE/VCO2 slope go beyond the simple description of ventilatory inefficiency (or excessive ventilation). Numerous clinical scenarios deserve our attention to identify patterns compatible with relative alveolar hypoventilation and values considered “pseudonormal”. In this sense, we believe that this analytical reflection and the descriptive proposal of VE/VCO2 slope values within ranges considered as “normoventilatory”, but which should be described as within pseudonormality criteria, is appropriate. Such situations observed […]
