An automatic positive airway pressure (AutoPAP) therapy device can be configured such that the minimum and/or maximum pressures deliverable by the device can automatically change. The minimum and/or maximum pressures can change as a function of pressures delivered over the course of the current therapy session and/or over the course of prior therapy sessions. The minimum and/or maximum pressures can also change as a function of the presence, absence, type, severity, or length of sleep disordered breathing events (SDBE) detected by the device over the course of the current therapy session and/or over the course of prior therapy sessions.

Phyto material tablets, tablet vaporizers, methods and apparatus for forming phyto material tablets. The tablets are formed to increase vaporization efficiency. Tablets can include break regions to facilitate fracturing into multiple pieces for vaporization. The tablets can also include multiple layers of different phyto material mixtures. Compression molds are used to shape the tablets. The compression molds can be provided on a rotational assembly to facilitate rapid manufacturing of multiple tablets. The vaporizers include heating chambers that are configured to increase the surface area of the tablets exposed for vaporization. The heating chambers include compression or fracture members that compress and/or encourage fracturing of the tablets to assist vaporization.

A patient treatment system includes a ventilation bag, and a monitoring device which is configured so as to be connectable to the ventilation bag. The monitoring device measures the pulse rate derived from the heart rate of a neonate, from signals of ECG electrodes which are connected to the monitoring device. In a case where an abnormality of measurement information of the pulse rate is detected, the monitoring device notifies of first information prompting ventilation by the ventilation bag.

A pressure safety device is used with a bag valve mask (BVM) for preventing over-pressurization. The BVM includes a bag assembly having a bag connector for detachably mating to a mask connector on a patient mask. The pressure safety device has a housing with a bag port, a mask fitting, and a flow path from the bag port to the mask fitting. The bag port detachably connects to the bag connector on the BVM, and the mask fitting detachably connects to the mask connector on the BVM. The pressure safety device includes an automatic flow reduction valve located on the flow path in the housing and impedes flow when pressure on a bag connector side of the valve exceeds a maximum threshold value.

The present document describes a flow measuring apparatus for measuring a flow through a section of an inhalation apparatus, comprising at least one set of Pitot tubes first a second Pitot tube and streamlinings extending longitudinally parallel to the Pitot tubes and the set of Pitot tubes is configured for traversing entirely a lumen which define the section of the inhalation apparatus and are respectively fluidly connected to a differential pressure sensor for measuring a difference between a stagnation pressure and a static pressure within the flow measuring apparatus.

An inhaler configured and adapted for inhaling an inhalation medium, enriched with active ingredients and/or flavouring substances, includes a cartridge carrier, a storage tank which contains the inhalation medium, a mouthpiece which is associated with the cartridge carrier, and an actuating mechanism for releasing the inhalation medium out of the storage tank in the direction of the mouthpiece. The inhaler has at least one sensor associated with the mouthpiece. The sensor is configured and adapted to detect characteristics of lips of the person using the inhaler and to provide a data signal formed from the characteristics. The sensor is connected to an electronic control unit associated with the inhaler, to which the actuating mechanism is also connected, in such a manner that the inhalation medium is released on the basis of the data signal. A corresponding arrangement and a corresponding method are disclosed.

Aspects and embodiments of the present invention generally include a device for patient self-administration of a prescribed medication. The device makes available for administration the precise quantity of medication constituting a dose at times designated by a health care provider (HCP). Preferably, the device also detects and transmits information to a remote management system accessible to the HCP, including detected attempts to tamper with the device. Advantageously, HCPs may render oversight and control over the device and its use to mitigate risks associated with patients self-administering medication without in-person supervision. This control may include establishing prerequisites the patient must meet prior to a dose being made available, or remote deactivation of the device. This oversight by the HCP may include patient-specific and aggregate data analysis for optimization of treatment or evaluation of the safety and efficacy of a treatment. Furthermore, this oversight may be conducted via a web-based interface.

A method of manufacturing a patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to the patient's airways includes collecting anthropometric data of a patient's face. Anticipated considerations are identified from the collected anthropometric data during use of the patient interface. The collected anthropometric data is processed to provide a transformed data set based on the anticipated considerations, the transformed data set corresponding to at least one customised patient interface component. At least one patient interface component is modelled based on the transformed data set.

High flow therapy is used to treat Cheyne-Stokes respiration and other types of periodic respiration disorders by periodic application of high flow therapy, adjustment of high flow therapy flow rates and/or periodic additions of CO2 or O2 into the air flow provided to the patient.

An oxygen concentration system may comprise a pressure sensor, a movement sensor, and a controller configured to use one or more pressure signals obtained from the pressure sensor and a movement signal obtained from the movement sensor to determine when to release a bolus of oxygen enriched air. In some implementations, the controller may adjust a trigger threshold based on an initial pressure signal obtained from the pressure sensor and the movement signal obtained from the movement sensor. In some implementations, the controller may adjust a pressure signal obtained from the pressure sensor based on the movement signal obtained from the movement sensor. In some implementations, the controller may detect a potential onset of inhalation from a pressure signal obtained from the pressure sensor and determine whether to verify the potential onset of inhalation based on the movement signal obtained from the movement sensor.
