INTRODUCTION Automatic ventilation for patients with respiratory failure aims at reducing mortality and can minimize the workload of clinical staff, offer standardized continuous care, and ultimately save the overall cost of therapy. We therefore developed a prototype for closed-loop ventilation using acute respiratory distress syndrome network (ARDSNet) protocol, called autoARDSNet. METHODS ...
A modification of a common commercial Xe-133 ventilation device is described for mechanically assisted ventilation imaging. The patient's standard ventilator serves as the power source controlling the ventilatory rate and volume during the xenon study, but the gases in the two systems are not intermixed. This avoids contamination of the ventilator with radioactive xenon. Supplemental oxygen and...
در چندین دهه اخیر، تکثیر جهانی کامپیوترها، سیستم های الکترونیکی و تجهیزات قابل انتقال، باعث شده که طراحان و محققان تمرکز بیشتری بر طراحی سیستم های ولتاژ و توان پایین داشته باشند. یک ota ولتاژ و توان بسیار پایین در این پروژه پیشنهاد شده است. برای طراحی مدارات ولتاژ پایین، آینه جریان ها و طبقات ورودی و خروجی بررسی می شوند. روش های زیادی برای طراحی otaهای ولتاژ و توان پایین وجود دارد. یکی از این...
Natural ventilation is one of the most essential issues in the concept of high-performance architecture. The porosity has a lot to do with wind-phil architecture to meet high efficiency in integrated architectural design and materialization a high-performance building. Natural ventilation performance in porous buildings is influenced by a wide range of interre...
We protect ourselves from airborne cross-infection in the indoor environment by supplying fresh air to a room by natural or mechanical ventilation. The air is distributed in the room according to different principles: mixing ventilation, displacement ventilation, etc. A large amount of air is supplied to the room to ensure a dilution of airborne infection. Analyses of the flow in the room show ...
