OBJECTIVE To assess the value of a spontaneous breathing trial (SBT) using a flow-inflating bag in predicting extubation success. Secondary goals were to evaluate the positive and negative predictive accuracy of a 15-min SBT. DESIGN Prospective, blinded, clinical study. SETTING Pediatric intensive care unit (ICU) of a university hospital PATIENTS Infants and children intubated for >or=24 ...

The new century brought a “new” kid on the block to the field of intensive care. Ultrasound (US) came from the radiology departments, and it has renewed intensive care medicine. Focused on the critical care patient and with the intensivist as a performer, US has set a new paradigm for medicine. Due to its increasing relevance, in 2009,(1) the American College of Chest Physicians and La Société ...

Background. Spontaneous breathing trials (SBTs) are standard of care in assessing extubation readiness; however, there are no universally accepted guidelines regarding their precise performance and reporting. Objective. To investigate variability in SBT practice across centres. Methods. Data from 680 patients undergoing 931 SBTs from eight North American centres from the Weaning and Variability...

Statistical analysis is used to analyze seven temporal series obtained from respiratory flow signals of 66 patients on weaning trials. In which, 33 patients belong to successful group (SG), and 33 patients belong to failure group (FG), i.e. failed to maintain spontaneous breathing during trial. Patients were then classified with a pattern recognition neural network, obtaining 78.78 % of accurac...

OBJECTIVE The failure to wean from mechanical ventilation is related to worse outcomes after cardiac surgery. The aim of this study was to evaluate whether the serum level of B-type natriuretic peptide is a predictor of weaning failure from mechanical ventilation after cardiac surgery. METHODS We conducted a prospective, observational cohort study of 101 patients who underwent on-pump coronar...

BACKGROUND Early detection of respiratory overload is crucial to mechanically ventilated patients, especially during phases of spontaneous breathing. Although a diversity of methods and indices has been established, there is no highly specific approach to predict respiratory failure. This study aimed to evaluate acceleration sensors in abdominal and thoracic wall positions to detect alterations...

PURPOSE To determine if the measurement of minute ventilation recovery time (V (E)RT), a recently proposed predictor of extubation outcome, can be reproduced using a more practical, simpler method. METHODS A case series with convenience sampling was performed in the surgical intensive care unit of a tertiary-care hospital. Nineteen patients were enrolled during weaning from mechanical ventila...

purpose: patterned breathing allows standardized serial measurements of heart rate variability and baroreflex indices. the slow breathing augments these parameters, and regular exercises, including yoga breathing practices with even respiratory rates have long-term beneficial effects in cardiovascular diseases. the role of temporization of breathing phases, i.e. the ratio of expiration to inspi...

BACKGROUND The effectiveness of noninvasive ventilation (NIV) after extubation in preventing post-extubation respiratory failure is still controversial. METHODS We conducted a prospective, multicenter randomized controlled study involving patients on mechanical ventilation for > 48 hours who tolerated a 2-hour spontaneous breathing trial and were subsequently extubated. The patients were ran...
