Abstract: The new neonatal ventilation methods have been developed along with utilization of new technological tools.This device is synchronized with the patient’s respiratory efforts. The ideal synchronized breath needs to be synchronous with initiation, size, and termination of the breath without delay in detecting of initial resiratory effort by device .The synchrony of respiration contribut...

The objective of the present study was to evaluate incentive spirometers using volume- (Coach and Voldyne) and flow-oriented (Triflo II and Respirex) devices. Sixteen healthy subjects, 24 +/- 4 years, 62 +/- 12 kg, were studied. Respiratory variables were obtained by respiratory inductive plethysmography, with subjects in a semi-reclined position (45 masculine). Tidal volume, respiratory freque...

To investigate the effect of lung volume on chest wall and lung mechanics in the rats, we measured the impedance (Z) under closed- and open-chest conditions at various positive end-expiratory pressures (0-0.9 kPa) by using a computer-controlled small-animal ventilator (T. F. Schuessler and J. H. T. Bates. IEEE Trans. Biomed. Eng. 42: 860-866, 1995) that we have developed for determining accurat...

Recent studies have shown that application of the ARDSNet low tidal volume strategy (i.e. allowing an increase in respiratory rate in order to minimize hypercapnia in those with low tidal volume) may generate consistent auto-PEEP (positive end-expiratory pressure), and this is not efficient in improving clearance of carbon dioxide. The present commentary deals with some of the recent controvers...

OBJECTIVES To investigate the effectiveness of respiratory physiotherapy based on clinical evidence and analyze the improvement in respiratory parameters. METHODS A prospective study was carried out in the Bone Marrow Transplant Unit of the Universidade Estadual de Campinas (UNICAMP). Two different previously established respiratory physiotherapy protocols were applied from days D-1 to D+7 th...

introduction: some studies have suggested correlation between mpv index and inflammatory diseases such as rheumatoid arthritis in adults. though bronchopulmonary dysplasia is also an inflammatory disease which develops in preterm neonates with respiratory distress syndrome, we decided to study the possible correlation between the mean platelet volume (mpv) and the occurrence of bronchopulmonary...

background extraperitoneal laparoscopy has become a common technique for many surgical procedures, especially for inguinal hernia surgery. investigations of physiological changes occurring during extraperitoneal carbon dioxide (co2) insufflation mostly focused on blood gas changes. to date, the impact of extraperitoneal co2 insufflation on respiratory mechanics remains unknown, whereas changes ...
