A RSBI score of less than 65 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. [4]

1 Aug 2005 To successfully wean a patient the artificial airway needs to be removed. For this to happen, good upper airway reflexes are needed, including an

Regardless of the use of these predictive parameters, the spontaneous breathing trial (SBT) is recommended. In the case of ventilator weaning, Haas says protocols managed by non-physician health care providers have been around since the late 1990s and have been proposed as a best practice since the release of a clinical practice guideline (CPG) in 2001. Weaning Parameters • Used to predict weaning readiness • Weaning parameters are categorized into 3 groups – Evaluation of ventilatory drive – Ventilatory muscle capability – Ventilatory performance • Rapid Shallow Breathing Index (RSBI) is the most accurate parameter for weaning success • The best predictor for extubation readiness is a SBT Examples of weaning criteria are: O 2 saturation maintained at greater than 92%, Fi o2 requirements less than 40% to 50%, respiratory rate less than 35, respiratory rate to TV ratio less than 100 breaths/min/L, and no signs of distress. 38 When these criteria are met, trials of breathing without support are attempted. At least three of the following criteria were required to continue with the procedure: maximal inspiratory pressure equal to or lower than -25 cm H20 RR below or equal to 35 breaths/min vital capacity equal to or above 10 ml/kg of body weight O2 sat greater than 90% for an inspired oxygen fraction Weaning is the process of liberation from, or discontinuation of, mechanical ventilatory support (‘weaning’ per se is not always required, ‘liberation’ may be a better term!) Weaning comprises 40% of the duration of mechanical ventilation 20% to 30% of patients are difficult to wean from invasive mechanical ventilation weaning trials, the presence of respiratory muscle fatigue, and extubation potential. SWC are good negative predictors that the weaning attempt will be unsuccessful but poor positive predictors that the weaning attempt will be successful.3 Regardless, SWC provide information about respiratory muscle strength and endurance.

Although the international consensus conference in 2005 did not recommend their routine use for clinical decision making, researchers did not stop working in this area. The weaning process itself can be quite lengthy, often accounting for approximately 25% of the total time on the ventilator. ([FOOTNOTE=Blackwood, B., Burns, K. E., Cardwell, C. R., & O'Halloran, P. Protocolized versus non-protocolized weaning for reducing the duration of mechanical ventilation in critically ill adult patients. weaning parameters (Yang, 1991) a) f/Vt < 100 breaths/min./liter (1) calculation: (a) disconnect the patient from the ventilator for 1 minute (b) measure the spontaneous minute ventilation and the respiratory rate (c) calculate the average tidal volume (in liters) as the minute ventilation ÷ the respiratory rate SBT should be repeated three times. Make sure to give the patient time to rest between each trial. 3.

One important parameter for MV weaning from MV is P 0.1, which indicates central respiratory activity; however, in order to determine P 0.1, an esophageal balloon or ventilators should be introduced (tracheal P 0.1 is also considered to be an accurate MV weaning parameter). Standard weaning criteria (SWC) evaluate respiratory muscle strength and endurance by using negative inspiratory force (NIF) and positive expiratory pressure (PEP). Another index, the rapid shallow breathing index or ratio of respiratory frequency to tidal volume (f/VT) identifies a breathing pattern associated with unsuccessful weaning. impression are not 100% accurate, the weaning parameters can be useful, especially in situations in which the decision as to weaning is difficult. Keywords: Weaning; Intensive care units; Ventilators, mechanical; Respiration, artificial.

For example, one randomized controlled trial reported that the use of a common assessment parameter, the rapid-shallow breathing index, prolonged time on the

In addition, weaning parameters assess many different physiologic functions and may provide an insight into the reasons for ventilator dependency. A number of parameters, such as vital capacity (VC), 1 A RSBI score of less than 65 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.
