The Rapid Shallow Breathing Index as an Early Predictor for Intubation and Mortality in Patients Undergoing Non-invasive Mechanical Ventilation in Acute Respiratory Failure

Detailed Summary

There are some criteria such as the most frequently used parameters to predict the failure of non-invasive mechanical ventilation, the APACHE 2 score, the presence of pneumonia and ARDS in the etiology, and no improvement in one hour of treatment. However, APECHE 2 score, which is the broadest of these criteria and includes others, is a complex scoring in which a large number of parameters are evaluated together, dependent on laboratory results and still leaves the final decision to the physician with a complete evaluation. In addition, the APACHE 2 score is a more commonly used method for intensive care patients rather than emergency patients who need a quick decision. Therefore, there is a need for a fast and practical method that can predict NIMV failure and determine early intubation decision in the management of patients admitted to the emergency department with acute dyspnea. Rapid Shallow Breathing Index (RSBI) is a parameter calculated by dividing the respiratory rate by the tidal volume and is used to predict whether patients who are intubated in intensive care unit can be extubated successfully. The aim of this study is to evaluate the success of RSBI in predicting intubation and mortality in patients presented to the emergency department with acute respiratory failure and had NIMV indication.
