The measurement and failure simulations of basic ventilation modes

The subject of this project was the design and realization of laboratory measuring exercise on the mechanical ventilator. Pneumatic mechanical ventilator MARK8 from Bird Corporation Company was chosen as a pattern. It is usable for three basic ventilation modes. There are spontaneous, assist and controlled ventilation. We use Lilly type pneumotachometer for ventilation circuit evaluation from Hamilton company. It is usable for calm breathing. Differential pressure sensor Omega TX278-05D5V for difference pressure evaluation is being used. Also A/D card NI USB-9215 from National Instruments company as convertor to PC is being used. Measuring data are displayed in LabView. The Subject of Laboratory exercise is setting and measuring basic ventilation modes and failures simulation on the ventilation circuit.
