Lung diseases can be monitored by measurement of the respiratory admittance. The forced oscillation technique (FOT) is a widely used measurement technique to obtain respiratory admittance. The FOT applies small amplitude pressure oscillations (in the order of 0.1kPa) at the mouth of the patient. A resulting airflow generated by the patient as a response to the pressure oscillations is measured. Therespiratory admittance G is defined as the frequency dependent ratio between the resulting air flow and the imposed pressure. A lot of useful information is contained in the frequency range of spontaneous breathing (0.1 - 1 Hz).Therefore, a setup is developed that can generate pressure oscillations in this frequency range. To make the measurement technique clinically practical
for patients, the setup is designed so that the patient can continue breathing spontaneously during the measurement. This spontaneous breathing generates a signal in the same frequency range as the respiratory response. Since the setup does not allow to measure the breathing signal separately, the breathing signal is considered as a disturbance on the response signal. This work focuses on the separation of the breathing signal and the respiratory response in order to obtain the respiratory admittance.
