Our aim was to assess the impact of motor activity and of arousing stimuli on respiratory rate in the awake rats. The study was performed in male adult Sprague-Dawley (SD, n=5) and Hooded Wistar (HW, n=5) rats instrumented for ECG telemetry. Respiratory rate was recorded using whole-body plethysmograph, with a piezoelectric sensor attached for the simultaneous assessment of motor activity. All ...

This work introduces an MR-compatible active breathing control device (MR-ABC) that can be applied to lung imaging. An MR-ABC consists of a pneumotachograph for respiratory monitoring and an airway-sealing unit. Using an MR-ABC, the subjects were forced to suspend breathing for short time intervals, which were used in turn for data acquisition. While the breathing flow was stopped, data acquisi...

The purpose of this study was to obtain a respiratory signal with the use of an add-on device to a specific stereotactic body frame and evaluate precision and accuracy of the method, with the use of a dynamic phantom. The authors designed and constructed a simple add-on device which, attached to a stereotactic body frame, provides information of the patient's respiratory signal in every CT axia...

objectives we assessed the prevalence of three common viruses including; respiratory syncytial virus (rsv), human rhinovirus (hrv), and human metapneumovirus (hmpv), in children with acute wheezing. patients and methods ninety six wheezy children, 48 males (50%) and 48 females (50%)under the age of 5 years, were enrolled in the study. all patients visited as outpatients or inpatients when refer...

The rapid pace of change in modern medicine makes training on simulation platforms an absolute necessity. With the microprocessors the sophistication of simulators exploded. More recently medicine has developed simulators that are becoming increasingly sophisticated, especially in anesthesia training but also to train intensive care personnel. This is an area that will rapidly advance in the fu...
