Design and evaluation of a system assuring spontaneous breathing in patients connected to a high-frequency oscillatory ventilator
Original language description
Patients connected to a high-frequency oscillatory ventilator should be paralysed or highly sedated so that the ventilator is able to work. The aim of the study is to design a special "Demand Flow System" allowing spontaneous breathing in patients ventilated using a high-frequency oscillatory ventilator. The principle of the device is a fast and exact monitoring of pressure in the ventilator circuit, followed by a separation of the pressure signal components generated by the high-frequency oscillatory ventilator and by a patient's breathing activity. The latest mentioned signal is used for a real-time control of extra gas flow injected into the ventilatory circuit so that the extra gas flow compensates the pressure changes generated by the patient. Thedemand flow system was tested during an animal experiment. The system allows spontaneous breathing during high-frequency oscillatory ventilation and reduces imposed work of breathing by 80%.
