A patient interface for supplying a flow of breathable gas to the airways of a patient may comprise a heat and moisture exchanger (HME). The HME may be positioned in a flow path of the flow of breathable gas. The HME may absorb heat and moisture from gas exhaled by the patient and the incoming flow of breathable gas to be supplied to the patient's airways may be heated and moisturized by the heat and moisture held in the HME.

A vent device for a respiratory device, comprising one or a plurality of vents configured with a variable aperture size for communicating a flow of breathable gas. Said vent device being configured so that the cross section profile exposed to the flow of breathable gas communicating through the vent does not change as the aperture size changes. A vent device may comprise of a plurality of the said vents, wherein the aperture size of each vent may be controlled independently or together, and may be controlled according to one or more input signals from one or more sensors. Examples of suitable input signals include flow, pressure, noise, accelerometer outputs, orientation of a patient or presence of any obstructions. A patient interface or a patient conduit may comprise the vent device, or the vent device may be configured to connect with a patient interface or a patient conduit.

A connection assembly for a respiratory therapy system, comprising: an outlet assembly, said outlet assembly including an outlet housing and a swivelling disc located on said outlet housing, said outlet housing and said swivelling disc defining, at least in part, a recess; an outlet connector located at an end of a tube portion, said outlet connector including an electrical connector; and a cable having a first end to connect to the electrical connector and a second end to connect to at least one electrical component of the respiratory therapy system, said cable having a slack portion, wherein said outlet connector and said swivelling disc are rotatable in unison between a first position and a second position, and wherein the slack portion of the cable extends from the recess and wraps around the swivelling disc as the swivelling disc is rotated from the first position to the second position.

Methods and apparatus perform periodic breathing detection, such as Cheyne-Stokes respiration detection. The detection may be performed by one or more processors, such as by analysis of data from one or more sensors. In some cases, the detection may be based on an electrocardiogram (ECG) signal, such as from ECG electrodes and / or an accelerometer signal, such as from an accelerometer. An occurrence of periodic breathing may be detected based on features derived from the signal(s). For example, detection may be based on deriving a respiration signal from the sensed signal(s) and / or analysis of RR interval times or relative QRS amplitude values, which may be evaluated on a segment-by-segment basis. The detection may provide monitoring and reporting of the occurrence of periodic breathing by a monitoring device and / or provide a basis for controlling changes to a provided respiratory treatment or therapy, such as by a respiratory pressure therapy device.

A connection assembly for a respiratory therapy system, comprising: an outlet assembly, said outlet assembly including an outlet housing and a swivelling disc located on said outlet housing, said outlet housing and said swivelling disc defining, at least in part, a recess; an outlet connector located at an end of a tube portion, said outlet connector including an electrical connector; and a cable having a first end to connect to the electrical connector and a second end to connect to at least one electrical component of the respiratory therapy system, said cable having a slack portion, wherein said outlet connector and said swivelling disc are rotatable in unison between a first position and a second position, and wherein the slack portion of the cable extends from the recess and wraps around the swivelling disc as the swivelling disc is rotated from the first position to the second position.

A container for holding an item having un-dried, oil-based paint thereon. A box has a removable lid with an outlet hole. The lid extends horizontally across and then upwardly on the container defining a first area to hold the item and a second area to hold a container of material when activated by a liquid to give off a gas heavier than oxygen. The oxygen is forced through the outlet hole limiting drying of paint on the item.
