摘要:
The invention relates to improved apparatus and methods for respiratory inductive plesthysmography. The invention includes apparatus for measuring changes in the circumference of a subject comprising of an energisable conducting wire having two ends, engagement means for engaging said ends to form a gapless conducting loop, the engagement means being in electrical communication with the conducting wire. The relationship between the elements of the apparatus provides a reduced level of noise associated with a measureable signal attributed to the changes in circumference. Signals generated in the apparatus may be processed and communicated through various means for analysis of respiratory effort. A method is disclosed for measuring respiratory effort with a gapless conducting wire energised with current.

The present invention monitors and interprets physiological signals and spontaneous breathing events to detect the onset of arousal. Once the onset of arousal is determined, the present invention determines adjustments that are needed in the operation of a therapeutic device to avoid or minimize arousals. In one embodiment, the present invention includes one or more sensors which detect a patient's physiological parameters, a controller which monitors and determines the onset of arousal based on the physiological variables received from the sensor, and a therapeutic treatment device which is controlled by the controller. The sensor can be a combination of one or more devices which are able to monitor a physiological parameter that is used by the present invention to determine the onset of arousal or the onset of a sleep disorder. The sensors can be integrated into one unit or may operate independent of the others.

The present invention provides a methods and apparatus for gas delivery, in particular, a mask including at least one porous barrier defining at least two chambers in gaseous communication. The porous barrier may include a plurality of pores,which preferably define a tapered shape. The mask may include a pliable nasal cushion. The invention provides a method for providing pressurised gas to a subject by supplying gas from a pressurised source to a mask, transmitting the gas into a first chamber at a first pressure,transmitting the gas into a second chamber at a second pressure through a plurality of pores, and transmitting the gas from the second chamber through a mask exit.
