Abstract Correlation of Rapid Shallow Breathing Index And Successful Weaning From Mechanical Ventilator Support In Surgical Patients Caren M. Bonander 2001 Predicting successful weaning from mechanical ventilator support (MVS) has been a quest of critical care researchers for over a decade. Prolonged duration of MVS is costly and associated with poor outcomes. Early weaning from MVS is associated with decreased mortality and morbidity as well as cost and length of stay. Along with discomfort and increased risks to the patients, MVS comes at a very high cost. Estimated yearly cost in the United States of patients being on prolonged MVS totals approximately 25 billion dollars per year. Long-term MVS is associated with an increase in complications and costs. Research of surgical patients has been limited in the area of RSBI. Rapid Shallow Breathing Index has been predominately researched in medical patients. Abdominal and thoracic surgical patients are at higher risk for pulmonary complications because of pain related to the surgical incision as it impedes the patient from ventilating in normal volumes.
