BACKGROUND With adaptive support ventilation, respiratory rate and tidal volume (V(T)) are a function of the Otis least work of breathing formula. We hypothesized that adaptive support ventilation in an open lung ventilator strategy would deliver higher V(T)s to patients with acute lung injury. METHODS Patients with acute lung injury were ventilated according to a local guideline advising the...

INTRODUCTION Independent lung ventilation is a form of protective ventilation strategy used in adult asymmetric acute lung injury, where the application of conventional mechanical ventilation can produce ventilator-induced lung injury and ventilation-perfusion mismatch. Only a few experiences have been published on the use of independent lung ventilation in newborn patients. CASE PRESENTATION...

The aim of this article is to identify and interpret the data provided by modern ventilators that provide the greatest clinical help in evaluating respiratory mechanics during mechanical ventilation. In intensive care, respiratory mechanics can be assessed in dynamic conditions (no flow-interruption) or static conditions (occlusion techniques) to record compliance and resistance and to monitor ...

BACKGROUND Prolonged controlled mechanical ventilation depresses diaphragmatic efficiency. Assisted modes of ventilation should improve it. We assessed the impact of pressure support ventilation versus neurally adjusted ventilator assist on diaphragmatic efficiency. METHOD Patients previously ventilated with controlled mechanical ventilation for 72 hours or more were randomized to be ventilat...

The mode of ventilation used during awake extubation has not previously been studied. We conducted a randomised controlled trial comparing spontaneous respiration, intermittent positive pressure ventilation, and pressure support ventilation (each n = 13) for incidence and severity of peri-extubation complications following routine elective surgery. We found the severity of peri-extubation cough...

conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...
