Systems and/or methods for assessing the sleep quality of a patient in a sleep session are provided. Data is collected from the patient and/or physician including, for example, sleep session data in the form of one or more physiological parameters of the patient indicative of the patient's sleep quality during the sleep session, a subjective evaluation of sleep quality, etc.; patient profile data; etc. A sleep quality index algorithm, which optionally may be an adaptive algorithm, is applied, taking into account some or all of the collected data. Sleep quality data may be presented to at least the patient, and it may be displayed in any suitable format (e.g., a format useful for the patient to be appraised on the progress of the treatment, a format useful for a sleep clinician to monitor progress and/or assess the effectiveness of differing treatment regimens, etc).

Methods and apparatus for assessing sleep quality

A connection system for connecting gas delivery components of a Continuous Positive Airway Pressure system includes a first conduit with a first lumen forming a first part of a gas flow path for the breathable gas and a second conduit with a second lumen forming a second part of the gas flow path. The ends of each flexible connector include a magnets. The first and second flexible connectors are configured to be joined together to form a sealed connection by way of moving the first and second flexible connectors toward each other in an axial direction and are configured to be held together by a magnetic force between the first and second magnets. In addition, the first and second flexible connectors are configured to be separated from each other by pivoting the first and second connectors relative to each other.

Connectors for connecting components of a breathing apparatus

A patient interface includes a hollow base with an air inlet configured to be connected to an air delivery tube and receive the pressurized flow of respiratory gas. The hollow base further includes a pair of nozzles extending from the hollow base. Each nozzle is configured to receive the pressurized flow of respiratory gas from a respective one of the pair of air outlets. A continuous flexible adhesive strip of material configured to adhere to a side of the patient's nose and support the hollow base and the pair of nozzles on the patient's face to form a sealed airpath from the hollow base to the patient's nasal airways. The hollow base comprises a first portion from which the pair of nozzles extend and a second portion that is attachable to the air delivery tube. The second portion is more rigid than the first portion.

Patient interface systems

A system for delivering a pressurized flow of breathable gas to a patient includes a patient interface and a flow generator mounted on the patient interface. The patient interface is configured to contact the patient's head and includes a frame and a cushion supported by the frame and configured to sealingly connect the patient interface to the patient's face and form a chamber between the frame and the patient's face. An inlet port in the frame is configured to receive the pressurized flow of breathable gas. The flow generator is configured to generate the pressurized flow and is capable of creating a pressure of about 2-40 cm HO in the chamber. In addition, a pressure sensor assembly spans from an outlet port of the flow generator to the inlet port of the patient interface.

Mask and mask-mounted flow generator system

A head-mountable flow generator is configured to deliver a flow of breathable gas at a continuously positive pressure with respect to ambient air pressure to a patient interface in communication with an entrance to a patient's airways including at least an entrance of the patient's nares, while the patient is sleeping, to ameliorate sleep disordered breathing. The flow generator includes a motor, an impeller assembly and housing that encases the motor and the impeller assembly. The housing is configured to be mounted on the patient's head and comprises an inlet to receive the flow of breathable gas and a pair of opposing outlets to deliver the flow of breathable gas. In addition, the impeller assembly is configured to pressurize the flow of breathable gas received from the inlet, and the housing is configured to convey the pressurized flow of breathable gas through both outlets.

Respiratory apparatus

A patient interface assembly includes a flexible cushion configured to sealingly engage the patient's nares and a frame with a pair of flexible extending members that extend laterally from opposite sides of the frame. The frame and the flexible cushion together form a chamber. The patient interface assembly also includes a positioning and stabilising structure configured to maintain the flexible cushion in engagement with the patient's nares. The positioning and stabilizing structure has a pair of headgear straps. Each headgear strap is connected to a respective one of the flexible extending members. The flexible extending members do not form an airflow path for the breathable gas. The headgear straps have a multi-layered structure, at least one layer being made of fabric and at least one layer being made of plastic. In addition, the at least one plastic layer is a rigidizer that adds rigidity to the respective headgear strap.

Unobtrusive interface system

A mask cushion or a mask assembly therewith provides a comfortable and effective seal for provision of a gas therapy by a respiratory treatment apparatus. The mask cushion may be integrated with or coupled to a mask frame. The mask cushion typically includes an inner cushion component. The mask cushion also includes a patient facial-contact side portion with a chamber and a barrier to form the chamber that may be flexible. The chamber may serve as an outer layer with respect to the inner cushion component. The chamber may be partially or completely filled with a gas, fluid or gel. The inner cushion may be formed with a soft flexible material such as an elastomer or foam, etc. The barrier may be a membrane and may also be soft flexible material.

Cushion assembly for a respiratory mask

A vent arrangement is provided to a mask or associated conduit to discharge exhaled gas from the mask to atmosphere. The vent arrangement is structured to diffuse the exhaust vent flow to produce less air jetting, thereby increasing the comfort of the patient and their bed partner. For example, the vent arrangement may include one or more grill components and/or media constructed and arranged to diffuse vent flow.

Mask vent

A patient interface includes a hollow base with an air inlet configured to receive the pressurized flow of respiratory gas in a first direction. The hollow base further includes a pair of air outlets configured to discharge the pressurized flow of respiratory gas in a second direction that is substantially parallel to the first direction. The patient interface also includes a pair of nasal posts. Each nasal post is removably connected to a respective air outlet of the hollow base and is configured to sealingly engage one of the patient's nostrils. In addition, the patient interface includes an adhesive support configured to support the hollow base and nasal posts on the patient's face. The adhesive support is configured to adhere to the patient's nose. An end of each nasal post comprises a ring configured to interlock with the respective air outlet to secure the nasal post with the air outlet.

A gas delivery component of a CPAP system is configured to magnetically connect to a second gas delivery component of the CPAP system to deliver a pressurized flow of breathable gas to a patient's airways. The gas delivery component includes a lumen forming a first part of a gas flow path for the breathable gas. A connection end of the gas delivery component is configured to engage the second gas delivery component. In addition, a magnetic connection assembly is located at the connection end and includes a magnet positioned at least partially within the lumen. The magnetic connection assembly is configured to magnetically secure the gas delivery component to the second gas delivery component.

A patient interface is configured to deliver a flow of pressurized breathable gas to a patient's airways. The patient interface includes a central portion with an opening configured to deliver the pressurized breathable gas to the patient's nares. A first stabilizing portion extends from the central portion and is structured to engage an outer side of a respective one of the patient's nostrils. A second stabilizing portion is opposite the first stabilizing portion and extends from the central portion. In addition, the second stabilizing surface is structured to engage an outer side of a respective one of the patient's nostrils. The central portion, the first stabilizing portion and the second stabilizing portion cooperate to form a U-shape configured to cradle the patient's nose so that the tip of the patient's nose remains exposed when the patient interface is mounted on the patient's face.

A mask system for delivering air pressurized above atmospheric pressure to the airways of a patient to treat sleep disordered breathing (SDB) by continuous positive airway pressure (CPAP) may include a mask having a cushion configured to form a seal with the patient's nose; two inlet conduits, each of the two inlet conduits configured to extend from a position superior to the patient's head and along a corresponding side of the patient's head, and each of the two inlet conduits being in fluid communication with a corresponding side of the mask to deliver pressurized air to the mask; a first vent arrangement configured to be positioned superior to the patient's head in use and configured to discharge gas to atmosphere during therapy; and a second vent arrangement configured to be positioned inferior to the first vent arrangement in use and configured to discharge gas to atmosphere during therapy.
