Rapid shallow breathing index – a key predictor for noninvasive ...
Mar 22, 2007 · A receiver-operating-characteristic curve was constructed based upon the dataset in increments of 10 for the RSBI (Figure 2). An RSBI > 120 yielded a sensitivity of 0.81 and a specificity of 0.74 for determining the need for NIV. A likelihood ratio positive (LR+) of 3.14 further illustrates the formidable predictive value of the 120 RSBI.
Role of the rapid shallow breathing index to predict the success of ...
Mar 17, 2014 · During the RSBI step, RSBI was recorded and blinded to the researcher. The liberation process was continued regardless of the RSBI result. The primary outcome was the success rate of mechanical ventilator liberation with or without RSBI.
Respiratory distress observation scales to predict weaning …
Jun 6, 2022 · The RSBI defined by the respiratory rate/tidal volume ratio (fR/VT) was continuously obtained from the ventilator. Study design Patients enrolled in the study underwent a 30-min SBT (shorter in case of obvious clinical intolerance) with pressure support and positive end-expiratory pressure set to zero, while FiO 2 remained unchanged [ 25 , 26 ].
Can diaphragmatic ultrasonography performed during the T-tube …
Sep 28, 2016 · Background The rapid shallow breathing index (RSBI), which is the ratio between respiratory rate (RR) and tidal volume (VT), is one of the most widely used indices to predict weaning outcome. Whereas the diaphragm plays a fundamental role in generating VT, in the case of diaphragmatic dysfunction the inspiratory accessory muscles may contribute. If this occurs …
Respiratory support in patients with acute respiratory distress ...
Sep 12, 2017 · Acute respiratory distress syndrome (ARDS) is a common condition in intensive care unit patients and remains a major concern, with mortality rates of around 30–45% and considerable long-term morbidity. Respiratory support in these patients must be optimized to ensure adequate gas exchange while minimizing the risks of ventilator-induced lung injury. …
Do heart and respiratory rate variability improve prediction of ...
Apr 8, 2014 · Introduction Prolonged ventilation and failed extubation are associated with increased harm and cost. The added value of heart and respiratory rate variability (HRV and RRV) during spontaneous breathing trials (SBTs) to predict extubation failure remains unknown. Methods We enrolled 721 patients in a multicenter (12 sites), prospective, observational study, …
Utilization of spontaneous breathing trial, objective cough test, …
Oct 31, 2023 · The objective measurement of cough, cuff leak test, RSBI, and diaphragmatic ultrasound results are described in Table 2. Only 26 patients had an RSBI > 105. Only 26 patients had an RSBI > 105. Among the 349 patients in whom the SBT was a success and who were extubated, 31 (8.9%) required reintubation within 48 h.
Flow Index - BioMed Central
Jun 7, 2021 · The RSBI , which, by expressing an imbalance between load and effort, could be deemed as a sign of inadequate inspiratory support was not taken into account in the primary analysis since our model included both RR and V T. Nonetheless, we performed an unplanned post hoc supplementary analysis evaluating the association between Flow Index and RSBI.
Prediction of extubation outcome in critically ill patients: a ...
Nov 15, 2021 · Background Extubation failure is an important issue in ventilated patients and its risk factors remain a matter of research. We conducted a systematic review and meta-analysis to explore factors associated with extubation failure in ventilated patients who passed a spontaneous breathing trial and underwent planned extubation. This systematic review was registered in …
Determining the mechanical ventilation mode and pressure …
Mar 17, 2014 · RSBI and other weaning parameters were calculated in different combinations (PS:5 PEEP:5, PS:0 PEEP:5, PS:5 PEEP:0, PS:0 PEEP:0) before T-tube trial in all patients. Measurements in the spontaneous ventilation was performed with the COSMOPLUS Novometrix device that has both capnography and respiratory monitorisation function; other measurements ...
