In the early phase of their disease process, patients with acute lung injury are often ventilated with strategies that control the tidal volume or airway pressure, while modes employing spontaneous breathing are applied later to wean the patient from the ventilator. Spontaneous breathing modes may integrate intrinsic feedback mechanisms that should help prevent ventilator-induced lung injury, a...
BACKGROUND In patients with post-extubation respiratory distress, delayed reintubation may worsen clinical outcomes. Objective measures of extubation failure at the bedside are lacking, therefore clinical parameters are currently used to guide the need of reintubation. Electrical activity of the diaphragm (EAdi) provides clinicians with valuable, objective information about respiratory drive an...
BACKGROUND Airway management of the obese patient presenting for surgery is more likely to be a challenging problem. Supraglottic airway device has been adopted as a bridge to connect ventilation and tracheal intubation in obese patients who would be suffered with difficult intubation. The optimum sevoflurane concentration for supraglottic airway device insertion allowing spontaneous breathing ...
Background: Successful weaning of the ventilator is a major challenge, especially in children. This study was conducted to compare the criteria of readiness for extubation and daily spontaneous breathing test (SBT) on the duration of mechanical ventilation and extubation failure rates. Materials and Metho...
R-R interval variability (RR variability) is increasingly being used as an index of autonomic activity. High-frequency (HF) power reflects vagal modulation of the sinus node. Since vagal modulation occurs at the respiratory frequency, some investigators have suggested that HF power cannot be interpreted unless the breathing rate is controlled. We hypothesized that HF power during spontaneous br...
High-frequency spinal cord stimulation (HF-SCS) is a novel technique of inspiratory muscle activation involving stimulation of spinal cord pathways, which may have application as a method to provide inspiratory muscle pacing in ventilator-dependent patients with spinal cord injury. The purpose of the present study was to compare the spatial distribution of motor drive to the parasternal interco...
An international phase iii randomised trial on the efficacy of helium/oxygen during spontaneous breathing and intermittent non-invasive ventilation for severe exacerbations of chronic obstructive pulmonary disease (the E.C.H.O.trial) P Jolliet, L Besbes, F Abroug, J Ben Kheli, M Besbes, J-M Arnal, F Daviaud, J-D Chiche, B Lortat-Jacob, J-L Diehl, N Lerolle, A Mercat, K Razazi, C Brun-Buisson, S...
INTRODUCTION Physiological determinants of weaning success and failure are usually studied in ventilator-supported patients, comparing those who failed a trial of spontaneous breathing with those who tolerated such a trial and were successfully extubated. A major limitation of these studies was that the two groups may be not comparable concerning the severity of the underlying disease and the p...
Weaning from mechanical ventilation is usually straightforward but is occasionally challenging. Sedation must be used at the appropriate times and with appropriate dosing. A protocol that calls for a daily sedation holiday with a spontaneous breathing trial decreases time on the ventilator. Early tracheostomy is beneficial in traumatic brain injury patients. Noninvasive ventilation is most usef...
