Efficiency of non-invasive positive pressure ventilation in the treatment of respiratory failure has been shown in many published studies. In this review article, we introduced new modalities of non-invasive ventilation (NIV), clinical settings in which NIV can be used and a practical summary of the latest official guidelines published by the European Respiratory Clinical Practice. Clinical tri...

Background Transient tachypnea of the newborn (TTN) is one of the most common neonatal respiratory disease and its symptoms usually begins in the first few hours after birth. The volume of fluid intake according to the neonate's conditions varies. We aimed to compare the restricted fluids volume with standard fluids volume in treatment of neonates with TTN. Materials and Methods: This clinical ...

Background & Aims: Elimination of carbon dioxide is related to the alveolar ventilation, respiratory rate and tidal volume. The aim of this study  to determine the effect of mechanical ventilation with different tidal volumes and constant minute ventilation on the end tidal Co2  and oxygen saturation during general anesthesia and to seek optimum parameters of mechanical ventilation during gener...

OBJECTIVE Ultrasonographic studies have demonstrated transient reduction in spleen volume in relation to apnea diving. We measured spleen volume under various respiratory conditions by MR imaging to accurately determine the influence of ordinary breath holding on spleen volumetry. MATERIALS AND METHODS Twelve healthy adult volunteers were examined. Contiguous MR images of the spleen were acqu...

BACKGROUND The effect of alterations in tidal volume on mortality of acute respiratory distress syndrome (ARDS) is determined by respiratory system compliance. We aimed to investigate the effects of different tidal volumes on lung strain in ARDS patients who had various levels of respiratory system compliance. METHODS Nineteen patients were divided into high (Chigh group) and low (Clow group)...
