摘要： In a method for assessing pulmonary stress, a flow of respiratory gas is supplied to the lungs of a subject, an ensuing pressure is measured in relation to time and the pressure-time relationship is analyzed. In this analysis, the profile of the pressure-time relationship is determined. In summary, the profile is straight when no stress is present, is convex when there is a risk for over-distension, and is concave when alveolar units are opened up. Implemented in a breathing apparatus the method can be used to assist an operator in diagnostic and therapeutic considerations in relation to a patient.

摘要： A ventilator has an inspiratory unit and an expiratory valve for regulating a flow of breathing gas and a control unit for controlling the inspiratory unit and the expiratory valve. In order to facilitate the opening of collapsed alveoli in the lungs, the control unit controls the inspiratory unit and the expiratory valve to generate a recruitment phase with an elevated basic pressure for the flow of breathing gas upon which a number of breaths is superimposed at a faster breathing rate.

摘要： A high-frequency oscillator ventilator has a first gas conduit with an opening for gas connection with a patient's airways and a bias gas flow inlet and a bias flow outlet disposed to define therebetween a flow path for a bias gas within the first conduit. An oscillator operable to alternately introduce a volume of additional gas from a source into, and to withdraw at least the same volume of gas from, the first gas conduit, thereby inducing pressure oscillations in gas within the first conduit to move gas along a path intersecting the flow path for a bias gas alternately into and out of the opening at a predetermined high-frequency dependent on the output of a control signal generator.
