Abstract (2. Language): 
In this study, control of tidal volume, respiration number and pressure value which are arrived to patient at mechanical ventilator device which is used in intensive care units were performed with fuzzy logic controller. The aim of this system is to reduce workload of aneshesiologist. By calculating tidal volume, respiration number and pressure value, the error Pe(k) between reference pressure value (Pref) and pressure of gas given ill person (Phasta) and error change rate Pe(k) were considered. Performed system is run with the pressure control ventilation (PCV) which is one of the most used modes among other ventilation modes. With the simulation study, it can be said that the obtained datas from the outputs of fuzzy controller are suitable for patients having lung disease.
Abstract (Original Language): 
Bu çalıĢmada, bulanık mantık denetleyici ile yoğun bakım ünitelerinde kullanılan mekanik ventilatör cihazında tidal volüm, solunum sayısı ve hastaya ulaĢan gaz basıncı değerinin kontrolü gerçekleĢtirilmiĢtir. Bu sistemdeki amaç anestezistin iĢ yükünün azaltılmasıdır. Tidal volüm, solunum sayısı ve basınç değeri hesaplanır iken, referans basınç değeri (Pref) ile hastaya verilen gazın basınç değeri (Phasta) arasında ki hata Pe(k) ve bu hatanın değiĢim oranı Pe(k) dikkate alınmıĢtır. GerçekleĢtirilen sistem günümüzde çokça kullanılan ventilasyon modlarından olan Basınç Kontrollü Ventilasyon (PCV) modu ile çalıĢtırılmaktadır. Benzetim çalıĢması ile bulanık kontrolörün çıkıĢından elde edilen veriler akciğer rahatsızlığı olan hastalar için uygun olduğu söylenebilir.
