Comparison of Ventilator Versus Traditional Measurement Methods of Rapid Shallow Breathing Index for Predicting Extubation Success

"Spirometer Measurement: The traditional method for calculating RSBI involves the use of a spirometer (Wright MK20; Ferraris Medical Ltd., Hertford, England), equipped with a disposable bacterial filter at the front end, connected to the artificial airway to measure the minute ventilation of the patient's spontaneous breathing over one minute.~Three Measurement Methods from the Ventilator: A. PSV at 5 cmH2O with PEEP at 5 cmH2O B. CPAP at 5 cmH2O C. CPAP at 0 cmH2O.~Electrical impedance tomography (EIT) will be secured around the patient's thorax using a silicone belt, positioned at the fifth or sixth intercostal space, with 16 evenly spaced electrodes. Measurement data will be obtained by passing a small electrical current around the chest, utilizing the principle of resistance."
