    Abstract: Certain examples described herein relate to acoustic detection mask systems and/or methods. In certain examples, an acoustic detection mask system is provided. An example acoustic detection mask system includes a mask having a microphone located therein or thereon. The microphone is connected to a data logger that is configured to capture vibrations and/or sounds registered by the microphone. The data logger may store such information in a computer readable storage media thereof for subsequent analysis, e.g., via a computer program accessing such data after the data logger is connected to a separate computer system. The microphone may be positioned and the data analyzed so as to determine differences between oral and nasal breathing, as well as sleep-disordered breath and/or snoring. Such components may be provided as a part of a system or in any suitable combination or sub-combination. Associated methods also are described herein as a part of the technology.

    Abstract: A patient interface for sealed delivery of a flow of air to ameliorate sleep disordered breathing may include: a seal-forming structure to form a pneumatic seal with the entrance to the patient's airways; a positioning and stabilising structure to maintain the seal-forming structure in sealing contact with an area surrounding the entrance to the patient's airways; a plenum chamber pressurised at a pressure above ambient pressure in use; a connection port for the delivery of the flow of breathable gas into the patient interface; and a device positioned within a breathing chamber defined, at least in part, by the seal-forming structure and the plenum chamber, wherein the device divides the breathing chamber into a posterior chamber and an anterior chamber, and wherein the device comprises a plurality of apertures such that turbulence of the air in the posterior chamber is less than turbulence in the air in the anterior chamber.

    Abstract: Methods of an apparatus determine a quantity of a body of water in a humidifier such as by indirect measurement. The quantity of water may be determined by measuring one or more properties or characteristics, from which the quantity of water may be inferred. Characteristics of a flow of air, the humidifier, and/or the body of water may be measured. The characteristics may be, for example, pressure, flow rate, noise, vibration, temperature, electrical or mechanical. These may be measured by one or more sensors, which may be located in the humidifier, RPT device, air circuit or the patient interface. The methods described may have advantages, for example in being able to detect the quantity of water without requiring sensors to be present in a disposable component, and in some cases, without introduction of additional sensors.

    Abstract translation: 设备的方法例如通过间接测量来确定加湿器中的水体的量。 水的量可以通过测量一种或多种性质或特性来确定，从中可以推断出水的量。 可以测量空气流，加湿器和/或水体的特性。 特性可以是例如压力，流速，噪声，振动，温度，电或机械。 这些可以由可以位于加湿器，RPT装置，空气回路或患者接口中的一个或多个传感器来测量。 所描述的方法可以具有优点，例如能够检测水的量而不需要传感器存在于一次性部件中，并且在一些情况下，不引入额外的传感器。
