Future studies in infants are needed to address respiratory mechanics during anesthesia, ideally in a specific age group and pathologies with high-risk postoperative complications. A better under- standing of respiratory system mechanics in children during general anesthesia may lead to a better titration of mechanical ventilation, preventing VILI.. Additional file 1: Respiratory mechanics measurements. Panel A shows Respiratory mechanics measurement protocol.

Thus, our findings declare a relatively novel effect of dexmedeto- midine infusion on respiratory mechanics in the popula- tion of morbidly obese patients with restrictive lung disease. The favourable effects for dexmedetomidine on oxygenation and lung mechanics in our patients were moderate. we reported an improvement of nearly 10% in the P/F ratio after 90-min dexmedetomidine infusion..

Background: During thoracic surgery in lateral decubitus, one lung ventilation (OLV) may impair respiratory mechanics and gas exchange. We tested a strategy based on an open lung approach (OLA) consisting in lung recruitment immediately followed by a decremental positive-end expiratory pressure (PEEP) titration to the best respiratory system compliance (C RS ) and separately quantified the elastic properties of the lung and the chest wall..

To minimize errors, baseline respiratory mechanics and hemodynamic data used in the statistical analyses were an average of the values col- lected during the first 12 h after ICU admission, and the 24-h corresponding values were an average of the 24 to 36-h values. of baseline MP, 24-h MP and the MP variation rate for ICU mortality rates..

In addition, general anesthesia with mechan- ical ventilation, by decreasing end-expiratory lung volume (EELV) and forming atelectasis, lead to a deterioration in respiratory mechanics and gas exchange [4, 5].

The mechanisms responsible for the changes in the respiratory mechanics following hemodilution are still to be fully characterized. The contradiction between the previous in vitro and the current in vivo results suggest that although hematocrit content and blood viscosity affect the mechanical proper- ties of the respiratory system, our present findings are governed mainly by systemic factors, such as the systemic catecholamine-release subsequent to blood loss [8]..

Nevertheless, our results suggest that PI rs is sufficiently accurate in estimating the MP gener- ated either by the ventilator or by respiratory muscles necessary to provide adequate gas exchange, with the observed increase in diagnostic accuracy of MP indices over the course of weaning most probably explained by our therapeutic interventions, which aimed at improv- ing respiratory mechanics and pulmonary gas exchange, leading to a fall of respiratory muscle workload below the individual fatigue

Keywords: Acute respiratory distress syndrome, Heterogeneity, Phenotype, Pneumonia, Respiratory failure, Sepsis. Acute respiratory distress syndrome (ARDS) is a clini- cal syndrome of inflammatory lung injury characterized by non-cardiogenic lung edema, severe hypoxemia and impaired lung mechanics [1, 2]. Clinicians and research- ers use a valid operational definition to identify patients with pathophysiological features of ARDS and implement.

In particu- lar, some respiratory nurses indicated that ‘lung attack’. This is the first known attempt to understand the respira- tory nurse perspective on use of the term ‘exacerbation’. In this sur- vey, respiratory nurses reported that patients did not fully grasp the meaning of the term ‘exacerbation’.

The average of gestational age in neonates with respiratory failure was 34 weeks, significantly lower than the control group with 38 weeks (p <. The most causing respiratory failure was respiratory disease 38.9%, premature 30.9%. Conclusion: The mortality was high in neonates with respiratory failure. The most causing respiratory failure was respiratory disease. Premature, low birth weight increased respiratory failure. Respiratory failure. Risk factors..

Laryngeal mask versus facemask in the respiratory management during catheter ablation. Results: During the RFCA, ETCO 2 values of the laryngeal mask group were higher than those of the facemask group (36.0 vs. The respiratory interval was significantly longer in the laryngeal mask group than those in the facemask group (4.28 s vs.5.25 s, p <.
