A RSBI score of less than 65 [3] indicating a relatively low respiratory rate compared to tidal volume is generally considered as an indication of weaning readiness. A patient with a rapid shallow breathing index (RSBI) of less than 105 has an approximately 80% chance of being successfully extubated, whereas an RSBI of greater than 105 virtually guarantees weaning failure.

In 1991, Tobin and Karl L. Yang published a study that described two new indices, the rapid shallow breathing index (RSBI) – initially known as the Yang Tobin Index (Y/T) – and the compliance, respiratory rate, oxygenation, and maximal inspiratory pressure (CROP) index.
Hypopnea is overly shallow breathing or an abnormally low respiratory rate.Hypopnea is typically defined by a decreased amount of air movement into the lungs and can cause hypoxemia (low levels of oxygen in the blood.)
Compared to placebo, participants who received the drug had a meaningful drop in the number of times they stopped breathing of had shallow breathing. Those who took Zepbound also lost more weight ...
In all of the methods below, the common endpoint measurement is a Rapid Shallow Breathing Index (Tobin Index) of less than or equal to 105. The RSBI ("Riz-bee") is simply the ratio of respiratory frequency in respirations per minute to tidal volume in liters (f/V t). Certainly, other measures such as patient's mental status should be considered.
Work of breathing is a measure of a "Rapid shallow breathing index". Peak/mean inspiratory and expiratory flow measures the presence of upper airway flow limitations during inspiration and expiration. %RCi is the percent contribution of the rib cage excursions to the tidal volume Vt. The %RCi contribution to Tidal Volume ratio is obtained by ...
Breathing irregularly—or forgetting to breathe—during screen time. /ˈskrēn ˈap-nē-ə/ There’s a physiological reason you feel tense when looking at your phone or computer.
Fig. 6: Shallow breathing using rib muscles. Shallow breathing, thoracic breathing, costal breathing or chest breathing [1] is the drawing of minimal breath into the lungs, usually by drawing air into the chest area using the intercostal muscles rather than throughout the lungs via the diaphragm. Shallow breathing can result in or be ...
