Abstract: The invention relates to an apparatus for supplying a respiratory gas to a patient within the context of diagnosis and/or therapy of sleep-related breathing disorders. In particular the invention concerns a CPAP unit with self-adaptive dual level pressure regulation.

Abstract: The invention concerns a breathing mask arrangement for feeding a respiratory gas to a patient. The invention further concerns a forehead support device for same. The breathing mask arrangement according to the invention includes an arch body, a sealing lip means for bearing against the surface of the face of a mask user, a respiratory gas conduit means for feeding respiratory gas to a mask internal space which is defined by the arch body and which is in communication with the nose and/or mouth opening of the user of the mask. The breathing mask arrangement according to the invention is distinguished by an application structure for application of the sealing lip means jointly with the arch body, wherein the application structure has a carrier portion on which a respiratory gas conduit member in the form of a docking port is releasably mounted.

Abstract: A holding device for a respiratory mask, especially for use in the field of sleep medicine, includes a headband which, in an application position, extends from the forehead area of the patient to behind the ear area of the patient, whereby the headband is provided with a flexible reinforcing insert for reinforcing the headband in a lateral direction. This makes it advantageously possible to provide the mask retention forces, which are necessary for reliably applying a respiratory mask, in a manner that is very compatible with regard to ergonomics.

Abstract: A method and a device for switching to the inspiration or expiration phase during CPAP therapy are disclosed. By means of a first high threshold value and a second low threshold value non-specific influences on the first derivative of the gas flow curve are suppressed in the corresponding breathing phase and the transition to the corresponding following gas phase is determined with high sensitivity. The invention further relates to methods for recognizing and suppressing the influence of the pulse or for switching to the inspiration phase in case of shallow breathing. The advantages of the invention are greater switching accuracy and improved safety for the patient.

Abstract: The present invention provides an automated respiration method involving positive airway pressure. The method comprises a step for measuring the respiratory gas flow and comparing it with a threshold value. A further step is provided for assessing any obstructive respiratory disturbance. An evaluation step evaluates the measurement values and determines whether it is a case of normal breathing, obstructive respiratory disturbance, non-obstructive respiratory disturbance or snoring. Depending on the results provided by the evaluation step, the positive airway pressure is either maintained or modified. It is the advantage of the invention that the respiratory gas flow as well as the airway obstruction are continuously measured, thereby enabling the positive air pressure to be adjusted to different individual states of the patient.

Abstract: The invention relates to a method and a device for detecting the respiratory activity of a person and for controlling the time progression of breathing gas pressure, especially in accordance with physical parameters and considering parameters indicating the momentary physiological condition of the breathing person. According to the invention, the device for detecting the respiratory activity of a person has at least one first device that provides a first signal indicating the breathing gas flow v, wherein at least one signal processing device is provided for processing said first signal. The signal processing device is configured in such a way that said device determines a reference relation on the basis of a first signal detected during a first time interval. On the basis thereof, said device determines a correlation relation between the reference relation and the first signal.

Abstract: A method of changing to the inhalation or exhalation phase in the CPAP therapy is provided. By means of a first, high threshold value and a second, low threshold value, nonspecific influences on the first derivative of the gas flow curve are suppressed in the respective breathing phase and the transition to the respective next gas phase is determined with high sensitivity. The advantages of the invention are in a higher precision of the changing operation and in a greater safety for the patient.
