ABSTRACT

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. Objective: to demonstrate that the ventilatory ratio is a prognostic marker in mechanically ventilated patients with SARS in the ICU of Hospital General La Villa. Material and methods: the exploratory analysis consisted of generating a correlation matrix using Pearson's correlation coefficient (r) as the test statistic. For the comparative analysis, an ANOVA was used in which we assumed homogeneous variances and normal distribution or a t-student test, each test was carried at a confidence level of 95%. To estimate the risk associated with mortality in patients with ARDS, a binary logistic regression model was used with the Logit method. For all quantitative analyses, p-value. Results: for the association of RV values with the probability of hospital mortality, a univariate logistic regression analysis was carried out, which showed that as RV values increase, the risk of mortality increases. (OR 3.07E+07 [4.657, 2.032e+11], p-value < 0.000). Conclusions: ventilatory ratio values can serve as an early indicator for the prognosis of mortality in patients with ARDS who have been admitted to the Intensive Care Unit.
