Abstract Analysing and fusing data from the medical devices of different disciplines (anaesthesiology surgery) inside operating rooms may promote awareness during surgical procedures. In this work, changes physiological parameters patients undergoing laparoscopic gynaecology procedures were analysed. The statistical relationship between intra-abdominal pressure airway peak was evaluated. Patien...

BACKGROUND Noninvasive ventilation is being increasingly used on preterm infants to reduce ventilator lung injury and bronchopulmonary dysplasia. The aim of this study was to evaluate the effectiveness of synchronized nasal intermittent positive pressure ventilation (SNIPPV) to prevent intubation in premature infants. METHODS Prospective observational study of SNIPPV use on preterm infants of...

BACKGROUND Airway pressure release ventilation (APRV) is a ventilatory mode, which allows unsupported spontaneous breathing at any phase of the ventilatory cycle. Airway pressure release ventilation as compared with pressure support (PS), another partial ventilatory mode, has been shown to improve gas exchange and cardiac output. We hypothesized whether the use of APRV with maintained unsupport...

BACKGROUND Spontaneous ventilation, mechanical controlled ventilation, apneic intermittent ventilation, and jet ventilation are commonly used during interventional suspension microlaryngoscopy. The aim of this study was to investigate specific complications of each technique, with special emphasis on transtracheal and transglottal jet ventilation. METHODS The authors performed a retrospective...

Severe respiratory failure in a patient with obstructive sleep apnoea was treated successfully with nasal intermittent positive pressure ventilation. Nasal intermittent positive pressure ventilation is a non-invasive method of respiratory support originally developed for the treatment of chest wall and neuromuscular disorders.'2 Recent studies suggest that this technique may be applicable to a ...

Cardioventilatory coupling (CVC) is the temporal coherence of respiratory and cardiac rhythms. We have suggested that this coherence is the result of triggering of inspiratory onset by a preceding cardiovascular afferent. One implication of this triggering hypothesis is that coupling should only exist under conditions of spontaneous ventilation and not under conditions where the ventilatory per...

I read with great interest the article by Raman et al 1 in a recent issue of CHEST (February 2015) that evaluated the pressure tolerance of esophagectomy anastomosis ex vivo and in vivo in a pig model in comparison with esophageal pressure during noninvasive positivepressure ventilation (NPPV). Th e authors showed that anastomosis can tolerate higher pressures than those transmitted to the esop...
