This paper proposed the Keyword Movement Disclose System (KMDS), which allows a facilitator of discussion to watch record moving keywords in Discussion Board (DBS). In DBS, participants place each keyword box made for item be discussed. The were expected show participant’s opinion and intention, because individual display was not disclosed other participants. Therefore, if can see true opinions...

A mathematical model of the respiratory system is introduced in this study. Geometrical dimensions of the respiratory system were used to compute the acoustic properties of the respiratory system using the electro-acoustic analogy. The effect of the geometrical proportions of the respiratory system is observed in the paper. Keywords—Electro-acoustic analogy, total lung impedance, mechanical par...

Mechanical ventilation is associated with increased survival of preterm infants but is also associated with an increased incidence of chronic lung disease (bronchopulmonary dysplasia) in survivors. Nasal continuous positive airway pressure (nCPAP) is a form of noninvasive ventilation that reduces the need for mechanical ventilation and decreases the combined outcome of death or bronchopulmonary...

Introduction The primary function of the lung is to exchange gases between the bloodstream and the environment. The anatomy and physiologic control mechanisms of the lung and its associated pulmonary circulation allow for optimal efficiency of gas exchange. Due to a need for brevity, this chapter addresses only the features of lung development and pulmonary physiology that may impact the care o...

results sixty patients were involved in this study. in asv mode, values including peak airway pressure (p-peak), end-tidal carbon dioxide (etco2), tidal volume and respiratory dead space were significantly lower than simv mode. although the mean value for dynamic compliance had no significant difference in the two types of ventilation, it was better in asv mode. methods in a crossover study, pa...
