摘要： The present invention provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.

摘要： The present invention provides a breathing assistance apparatus that has a convenient and effective method of cleaning internal conduits inside the apparatus. The breathing assistance apparatus is preferably a gases supply and humidification device. The cleaning method is a method of disinfection that is automated so minimal training is required to disinfect in particular an internal elbow conduit within the device. It is therefore not necessary to dismantle the gases supply and humidification device, therefore, inadvertent damage to the internal parts of the device is avoided. The present invention also provides a method of disinfecting a heated breathing conduit and a patient interface.

摘要： This invention relates to a breath indicator that is receivable by a part of a breathing assistance apparatus that supplies gas to a patient. The indicator comprises an elongate body having a gas sampling end and an attachment end. The attachment end is adapted to attach to a part of a breathing assistance apparatus and for locating the gas sampling end. The gas sampling end is to be located in a region where gas from the patient is to be exhaled. The gas sampling end being in communication with a sensor comprising a detector material changeable between a first visual indicator state relating to an inhalation phase of the patient, and a second visual indicator state relating to an exhalation phase of the patient. The detector material is capable of changing between the visual indicator states at a sufficient rate to substantially correspond with the inhalation and exhalation phases of the patient.

摘要： A respirator system includes a respirator with an air filter, a flow generator with a sensorless DC motor, a mask, a processor, a sensor, an electric power source, and a wireless transceiver. The respirator filters air, increase the pressure of the air, delivers the air to the mask at a pressure above ambient, gathers data with the sensor about operation of the respirator, and transmits the data. An intermediate electronic device is separate and remote from the respirator, and is configured to receive the transmitted data process the data, and re-transmit the data. A computer receives the data, processes the data and generates at least one report regarding the respirator or a user of the respirator.

摘要： Provided herein are systems, methods and devices for performing one or more titrations for oral appliance therapy. For example, a method for evaluating an outcome of oral appliance therapy in a subject is discussed herein. The method can include positioning an adjustable mandibular displacement device in an oral cavity of a subject and implementing an automatic titration protocol. The protocol can include controlling a protrusion level of the adjustable mandibular displacement device during a test period, monitoring physiological information from the subject during the test period, and analyzing the physiological information to evaluate the outcome of oral appliance therapy.
