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.

Hyperpnea – fast and deep breathing; Hyperventilation – increased breathing that causes CO 2 loss; Hypopnea – slow and shallow breathing; Hypoventilation – decreased breathing that causes CO 2 gain; Labored breathing – physical presentation of respiratory distress; Tachypnea – increased breathing rate
Tachypnea, also spelt tachypnoea, is a respiratory rate greater than normal, resulting in abnormally rapid and shallow breathing. [1]In adult humans at rest, any respiratory rate of 12–20 per minute is considered clinically normal, with tachypnea being any rate above that. [2]

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.
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 ...
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 ...
A patient with metabolic acidosis will often demonstrate a rapid breathing pattern, known as Kussmaul breathing. Rapid breathing helps the patient compensate for the decrease in blood pH by increasing the amount of exhaled carbon dioxide, which helps prevent further acid accumulation in the blood. [11] Cheyne–Stokes respiration is a breathing ...
