VARIABLES PREDICTING FOR DURATION OF MECHANICAL VENTILATOR ON ICU PATIENTS: RETROSPECTIVE STUDY

Abstract

This study aims the predictor variables for the duration of a ventilator in ICU patients. Method: This is a retrospective study design with 36 respondents who were selected by purposive sampling technique. This research data is secondary data obtained from the medical records of patients from January until December 2019. The instrument utilized was the observation sheet to observe the predictor variables for the mechanical ventilator duration. The statistical tests applied were the Spearman correlation test, logistic regression test, and ROC curve. Result: Based on the results of logistic regression, it was found that GCS (OR 16.114 (1.537-168.895), p-value 0.020), FiO2 (OR 0.778 (0.34-17.711), p-value 0.003), MSOFA (0.481 (0.053- 4.331, p-value 0.009), and based on this result found SpO2 / FiO2 ratio (OR 26.369 (2.755-252.373), p-value 0.005) is the most influential predictor of ventilator duration. The sensitivity of the SpO2 / FiO2 ratio was 42%, specificity of 36.1% (AUC 0.824, p-value 0.001). Conclusion: The SpO2/FiO2 ratio is the most influential predictor of the duration of ventilator use on ICU patients.
