Correlación índice de SAFI/PEEP con el índice de PAFI/PEEP en pacientes con SIRA y ventilación mecánica invasiva

Abstract

The assessment of oxygenation status of critically ill patients who developed ARDS is of paramount importance in order to establish interventions and prognosis of this. In institutions like the Luis Vernaza Hospital where the demand for critical care unit is high, the number of patients with this is entity is high. In its assessment PAFI / PEEP index, is used, however its implementation is not always easy to accomplish. SAFI / PEEP is a valuation method that is easier to calculate, however it is not known to what extent this relates to the first. Objectives: To determine the degree of correlation between the SAFI / PEEP and PAFI / PEEP index to evaluate patient’s oxygenation with ARDS. Method: A cross-sectional study that included at random 62 patients with ARDS admitted from August 1 to October 31, 2010 in the ICU. Patients were also requested the required parameters for calculating PAFI, SAFI and PEEP index. Statistical analysis: Analysis of linear correlation (R2) Results: The results showed a SAFI and PAFI’s correlation of 0.88 in patient admission to early for ARDS. PAFI/PEEP and SAFI/PEEP index showed a R2 coefficient 0.94. In both cases the coefficient under 72 hours: 0.31 SAFI y PAFI index and 0.54 when adding PEEP to both.
