摘要： The valve (14) comprises a housing (22) and a slider element (24) connected to a mask housing (26). During normal operation side ports (30, 34) are closed by element (24). The air flow to a patient must be sufficient to overcome the slight attractive force between magnets (36, 38). If the flow from the generator drops to below the level necessary to keep the slider element to the open position, the magnets move together allowing plate (39) to stop flow to the patient, who may breath unassisted through the side ports.

摘要： A nasal cushion (30) comprises a substantially triangularly shaped frame (32) from which extends a membrane (34). The frame (32) has a scalloped edge (36) by which the cushion (30) is affixed to a mask body. The membrane (34) has an aperture (38) into which the wearer's nose is received. The membrane (34) is spaced away from the rim (40) of the frame (32), and its outer surface (41) is of substantially the same shape as the rim (40). Respective notches (42, 44) receive the bridge of the wearer's nose. The wearer's nose is received through the aperture (38) into the chamber within the mask body (46). The seal forming portion (45) thus contacts both the surface of the wearer's nose and a portion of the wearer's face in the region between the base of the nose and the upper lip, and around the sides and over the bridge of the nose. The shape of the seal forming portion (45) is particularly suited to effectively seal the difficult region of the facial contour that is the crease between the sides of the nose and the face.

摘要： Methods and apparatus for determining leak and respiratory airflow are disclosed. A pressure sensor (34) and a differential pressure sensor (32) have connection with a pneumotach (24) to derive instantaneous mask pressure and airflow respectively. A microcontroller (38) estimates a non-linear conductance of any leak path occuring at a mask (12) as being the low pass filtered instantaneous airflow divided by the low pass filtered square root of the instantaneous pressure. The instantaneous leak flow is then the conductance multiplied by the square root of the instantaneous pressure, and the respiratory airflow is calculated as being the instantaneous airflow minus the instantaneous leak flow. The time constants for the low pass filtering performed by the microcontroller (38) can be dynamically adjusted dependent upon sudden changes in the instananeous leak flow.

摘要： The occurrence of an arousal in a patient associated with an apneic or hypopneic episode can be determined. Sensors (10) are placed on a patient to obtain signals representative of at least two physiological variables, for example skin conductance, heart rate and blood oxygen concentration. The signals are conditioned by conditioning circuitry (12), then processed by a processor (18) to correlate at least two thereof. A coincident change in at least two of the processed signals is indicative of the occurrence of an arousal, that in turn indicates an apneic or hypopneic episode has occurred. A patient thus can be diagnosed as suffering conditions such as obstructive sleep apnea.

摘要： A pair of nasal prongs (15), suitable for insertion into the lower portion of the nares, join together via a small plenum chamber (16) to form a single tube (17) conveying the nasal pressure towards an electrical pressure transducer (19). Another prong (20) is held in proximity with the patient's mouth. A baffle element (25) extends downwards from a location above the open end of the prong (20) to redirect a portion of oral airflow. The oral tube (21) extends towards the electrical pressure transducer (19), and conjoins with the nasal tube (17) at a junction (22) to form a common tube (18) connected to the pressure transducer (19). The relative lengths and/or diameters of the nasal tube (17) and the oral tube (21) are arranged so that the respective pneumatic impedances are different, so that the contributions of respiratory airflow from each of said tubes (17, 21) are substantially equal.

摘要： The apparatus provides for the determination of the instantaneous phase in the respiratory cycle, subject's average respiration rate and the provision of ventilatory assistance. A microprocessor (16) receives an airflow signal from a pressure transducer (18) coupled to a port (17) at a mask (11). The microprocessor (16) controls a servo (19), that in turn controls the fan motor (20) and thus the pressure of air delivered by the blower (10). The blower (10) is coupled to a subject's mask (11) by a conduit (12). The invention seeks to address the following goals: while the subject is awake and making substantial efforts the delivered assistance should be closely matched in phase with the subject's efforts; the machine should automatically adjust the degree of assistance to maintain at least a specified minimum ventilation without relying on the integrity of the subject's chemoreflexes; and it should continue to work correctly in the presence of large leaks.

摘要： A method of flow estimation during CPAP treatment is disclosed and involves measuring turbine (32) speed by means of the motor's Hall-effect sensors (80). The equivalent pressure, pest, that would be developed by the turbine (32) for that measured speed if the flow were zero is estimated using a predetermined mathematical function. Coincidentally with the speed measurement and pressure estimation, the delivery tube pressure, pact, is measured by the pressure transducer (42), and from pact together with pest, the difference between the two pressures is calculated, representing an estimation of flow, fest. The flow estimation value can be linearised by the square root device (86), and then filteredby the combination of low pass and high pass filters (90, 92) to derive a filtered flow estimate value, that has the non-respiratory components removed. A method of flow compensation of flow-induced pressure swings also is disclosed.

摘要： Apparatus (40) for monitoring oro-nasal respiratory flow is disclosed. The apparatus (40) is formed of a curved plate (42) to which is substantially perpendicularly arranged a planar member (44), the plate (42) and the member (44) are connected by a neck portion (46). Mounted in an upstanding fashion from the planar member (44) are two nasal prongs (48, 50). Two PVDF sensors (60) are mounted from, and lie in, the plane of the planar member (44), co-operating with a respective nasal prong (48, 50). A further PVDF sensor (80) in planar form is arranged to be downwardly directed and perpendicular to the planar member (44) so as to be located in the vicinity of the mouth when the apparatus (40) is being worn by a patient. The PVDF sensors (60, 80) deflect respectively under the influence of nasal and oral airflow, and generate electrical charge having a determined relationship with the airflow.
