The RSBI is defined as the ratio of respiratory frequency to tidal volume (f/VT). People on a ventilator who cannot tolerate independent breathing tend to breathe rapidly (high frequency) and shallowly (low tidal volume), and will therefore have a high RSBI.

Conclusions: In mechanically ventilated COPD patients with hypercapnic respiratory failure, the NIF threshold of ≤−25 cmH2O was a moderate-to-good predictor for successful ventilator liberation, and outperforms the traditional threshold of ≤−30 cmH2O.

Purpose: Rapid shallow breathing index (RSBI) is conveniently measured through the ventilator. If continuous positive airway pressure (CPAP) is used, it may change the RSBI value. We measured the RSBI with a handheld spirometer and through the ventilator, with and without CPAP, to assess differences.

Ventilator weaning is an important step in the care of ICU and RCU patients. It is the gradual removal of mechanical ventilatory support. Different predictors are used for initiation of weaning. This study was designed to investigate the rapid shallow breathing index (RSBI) as a predictor for successful weaning.

Sleep, especially during rapid eye movement (REM), also leads to lower muscle tone around the airway, Morgenthaler added. In other words, the muscles that support the airway relax, allowing the breathing tube to constrict. When the airway gets narrower, the velocity of the air moving through it increases.

We considered T-piece SBT to be the procedure of temporarily disconnecting a patient from the ventilator while maintaining an external oxygen supply, commonly by using a T-piece connected to the endotracheal tube.

B. Weaning parameters help predict patients who will fail a ventilator discontinuation attempt and are measured at the bedside: 1. The rapid shallow breathing index (RSBI) is calculated as the ratio of tidal volume (TV) in liters to respiratory rate (RR) in breaths/minute: RSBI = TV/RR.

The SBT is done while while the patient is intubated. An RSBI < 105 breaths/min/L has been widely accepted by healthcare professionals as a criteria for weaning to extubation. Whereas patients with RSBI > 105 will have a high chance of failure and require re-intubation.

An RSBI score of less than 105 is generally considered as an indication of weaning readiness. Once a patient passes a spontaneous breathing trail other considerations before extubation will need to be considered. Does the patient have a difficult airway?

Whereas patients with RSBI > 105 will have a high chance of failure and require re-intubation. As an example, a patient who has a respiratory rate of 20 breaths/min and a tidal volume of 400 mL/breath has an RSBI of (20 breaths/min)/ (0.40 L) = 50 breaths/min/L.
