摘要:
The present invention relates to a method and a respiration device having a respiration unit for generating an airflow for the respiration and having a monitoring unit. The monitoring unit is used to detect a respiration parameter and to classify events in the respiration on the basis of monitoring of the respiration parameter. In this case, the monitoring unit is able and designed to carry out an event analysis to recognize an occurrence, which is characteristic for Cheyne-Stokes respiration, of chronologically successive events and for this purpose to ascertain the period length thereof and to compare them to one another and to register the presence of Cheyne-Stokes respiration when the compared period lengths each deviate by less than 40% from one another.

A ventilator system (100/200/300/400) includes an integrated blower (130/230/330). In one case, the ventilator system includes: an inspiration port (122/222/322) for connection to an inspiratory limb (112/212/312) of a dual-limb patient circuit (110/210/310), and an expiration port (142/242/342) for connection to an expiratory limb (114/214/314) of the dual-limb patient circuit; a gas delivery device (120/220/320) connected to the inspiration port to supply a pressurized flow of gas to the inspiration port to generate a positive pressure; and a blower having an inlet (132/232/332) that is operatively connected to the expiration port and configured to be controlled to selectively supply a negative pressure level between 4 and 120 cmH2O to the expiration port, and an outlet (134/234/334) to exhaust gas received from the expiration port. In another case, the ventilator system includes a blower to generate positive pressure/flow to augment flow for noninvasive ventilation.

Systems and methods for collecting samples from a patient for diagnosis are provided. In many embodiments, the sample collection and analysis system concentrates particles emanating from a patient's cough, sneeze, or breathe in a sample for the diagnosis of a respiratory tract infection or other ailment of the patient. The sample collection and analysis system has a pre-collection assembly (that is patient interface, a collector in fluid communication with a sample reservoir that function in combination to: efficiently capture the volume of air expelled from the subject, direct the expelled air towards a sample reservoir, and separate the desired particle sizes from the expelled air into the sample reservoir.

A system, apparatus and methods are provided for supplying gases to a user. The supply includes a sub-therapeutic mode and a pressure support mode for delivering therapy to a user. A flow diversion device or valve switches from a first mode corresponding with the sub-therapeutic mode of the system to a second mode corresponding with the pressure support mode of the system. In the first mode, the valve opens a larger flow path between the interior of the user interface and ambient air than in the second mode.

A system for controlling the delivery of medical gases includes a digital signal processor that receives at least one ventilation parameter value change, calculates a fresh oxygen flow rate, total fresh gas flow rate into the breathing circuit, and a reference oxygen flow rate representative of a predetermined oxygen concentration delivered to a patient. A graphical display presents the calculated fresh oxygen flow rate, total fresh gas flow rate, and reference oxygen flow rate. A method of controlling the delivery of medical gases to a patient includes calculating a total fresh gas flow rate into the breathing circuit, calculating a fresh oxygen flow rate into the breathing circuit, calculating a reference oxygen flow rate representative of a predetermined oxygen concentration delivered to the patient and presenting the total fresh gas flow rate, the fresh oxygen flow rate, and reference oxygen flow rate on a graphical display.

A breathing arrangement includes a patient interface, at least one inlet conduit, and a headgear assembly. The patient interface includes a mouth covering assembly including a cushion structured to sealingly engage around exterior of a patient's mouth in use, a nozzle assembly including a pair of nozzles structured to sealingly engage within nasal passages of a patient's nose in use, and an element connecting the mouth covering assembly and the nozzle assembly. The at least one inlet conduit is structured to deliver breathable gas into at least one of the mouth covering assembly and the nozzle assembly for breathing by the patient. The headgear assembly is removably connected to at least one of the mouth covering assembly and the nozzle assembly so as to maintain the mouth covering assembly and the nozzle assembly in a desired position on the patient's face.

The invention relates to a device for performing respiratory training, in particular altitude training, comprising a mouthpiece (1) through which a person can exhale respiratory gas into a volume (2, 3a, 7) or can inhale it out of the volume (2, 3a, 7), wherein this volume (2, 3a, 7) is formed at least in part by a container (2) which is adjustable in terms of its volume and which is connected to the mouthpiece, wherein the volume (2, 3a, 7) adjoins one side of at least one gas-permeable membrane (4), to the other side of which at least one gas exchange chamber (3b) is connected, through which a fluid provided for the gas exchange, in particular CO2 and/or O2 gas exchange, can actively flow. Furthermore, the invention also relates to a method for performing respiratory training, in particular altitude training, wherein a person exhales into a training device through a mouthpiece (1) and inhales from this training device, wherein the O2 and/or CO2 partial pressure in the respiratory gas inhaled from the device is influenced by exchange of O2 and/or CO2 between the respiratory gas in the training device and a fluid provided for the gas exchange through at least one gas-permeable membrane (4).
