Mechanical ventilation can be life-saving for patients with acute respiratory failure. In between the 2 extremes of complete and no ventilatory support, both patient and machine contribute to ventilatory work. Ideally, ventilator gas delivery would perfectly match patient demand. This patient-ventilator interaction depends on how the ventilator responds to patient respiratory effort and, in tur...
The American Association for Respiratory Care has declared a benchmark for competency in mechanical ventilation that includes the ability to "apply to practice all ventilation modes currently available on all invasive and noninvasive mechanical ventilators." This level of competency presupposes the ability to identify, classify, compare, and contrast all modes of ventilation. Unfortunately, cur...
Mechanical ventilation can be perceived as a treatment with a very narrow therapeutic window, i.e., highly efficient but with considerable side effects if not used properly and in a timely manner. Protocols and guidelines have been designed to make mechanical ventilation safer and protective for the lung. However, variable effects and low compliance with use of written protocols have been repor...
These experiments tested the hypothesis that a relatively short duration of controlled mechanical ventilation (MV) will impair diaphragmatic maximal specific force generation (specific P(o)) and that this force deficit will be exacerbated with increased time on the ventilator. To test this postulate, adult Sprague-Dawley rats were randomly divided into one of six experimental groups: 1) control...
BACKGROUND Mechanical ventilation is a therapeutic action for newborns with respiratory diseases but may have side effects. Correct equipment knowledge and training may limit human errors. We aimed to test different neonatal mechanical ventilators' performances by an acquisition module (a commercial pressure sensor plus an isolated chamber and a dedicated software). METHODS The differences (Δ...
در پروژه حاضر تعیین ظرفیت حمل بار در رباتهای با مفاضل الاستیک به شیوه کنترل مود لغزشی ارایه می گردد همچنین روش تعیین ظرفیت حمل بار در این رباتها با استفاده از روش خطی سازی به وسیله بازخورد بهینه سازی می شود این پروژه ابتدا روش تعیین معادلات دینامیکی ربات با مفاصل الاستیک و اماده سازی آنها را برای کنترل به شیوه مود لغرشی ااریه می دهد. سپس الگوریتم کنترل مود لغرشی روی ربات در دو حالت عدم وجود و و...
