Relación ventilatoria elevada asociada a aumento de mortalidad en paciente con síndrome de dificultad respiratoria en unidad de cuidados intensivos

Introduction : considerable evidence supports lung dead space fraction as an independent predictor of mortality in ARDS. However, it is rarely measured or used in clinical practice. Primarily, this is due to the lack of a simple bedside index to monitor dead space and the additional expense associated with measurement in the critical care setting. Consequently, ventilation failure, despite its importance, is completely excluded as a stratifying variable in ARDS
