An aerosol generating device which is capable of generating an aerosol at an appropriate timing includes: a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a controller which controls the power supplied on the basis of the measurement value. The controller controls a power supply amount from the power source to be a first value when the measured value is equal to or larger than a first threshold and smaller than a second threshold larger than the first threshold, and the power supply amount to be larger than the first value when the measured value is equal to or larger than the second threshold.

A main unit connected to a vaporizer and controlling operation of the vaporizer includes: a processor; and a battery, a timer, and a memory that are connected to the processor. The processor controls the battery to provide energy for the vaporizer to allow the vaporizer to vaporize an aerosol-generating substrate. The processor calculates an accumulative temperature during vaporization of the vaporizer based on timing information of the timer and a vaporization temperature change curve stored in the memory.

A delivery device for and a method of delivering gases to the nasal airway, in particular therapeutic gases and gases in combination with active substances, either as powders or liquids, for enhanced uptake of the active substances.

Example embodiments relate to a method of protecting a surface of an e-vaping device portion from corrosion, the method including preparing a coating mixture configured to protect the surface from corrosion, and coating the surface with a protective coating based on the coating mixture, wherein the coating is performed via one of electrodeposition, dipping, spraying, and vapor deposition, and the coating mixture includes at least one of a silane and a resin.

Containment units, dry powder inhalers, delivery systems, and methods for the same are disclosed. Exemplary devices are configured to have inlets and outlets which are formed with the containment walls of a containment unit. Air jets formed by the configuration of inlet(s) and outlet(s) inside the containment unit create significant turbulence and deaggregate the powder. Delivery system components downstream of the containment unit may integrate the exiting aerosol plume with a low flow nasal cannula air stream for delivery to a subject.

A respiration device (1) supports cardio-pulmonary resuscitation (CPR) and a method for operating a respiration device (1) supports cardio-pulmonary resuscitation (CPR). The respiration device (1) has a control and regulation unit (7) in order to actuate an expiratory metering unit (3), and an inspiratory metering unit (2) such that, in a first phase, a current value of pressure is increased relative to a first pre-defined value (16) and such that, in a second phase, the current value of the pressure is reduced relative to the first pre-defined value (16).

Described is a system including an air pressure supply arrangement, a sensor and a titration device. The air pressure supply arrangement provides air pressure to a patient's airways. The sensor detects input data corresponding to a patient's breathing patterns of a plurality of breaths. The titration device receives and analyzes the input data to determine existence of breathing disorder and corresponding characteristics. The titration device generates output data for adjusting the air pressure supplied to the patient as a function of an index of abnormal respiratory events included in the input data.

A process and a device determine an indicator of an intrinsic end-expiratory pressure in the lungs of a patient. Embodiments are based on the device, ventilator with the device, and the process using the device that includes an interface arrangement configured for an exchange of information with a ventilation device and a control unit that determines first information on a first breathing pressure generated by muscles of the patient, at a first time, at which an inhalation attempt of the patient is present and determines second information on a second breathing pressure generated by the muscles of the patient, at a second time, at which breathing gas flow towards the patient starts. The control unit further determines the indicator of the intrinsic end-expiratory pressure based on the first information and based on the second information.

An electronic smoking device is provided including a power supply portion comprising a power supply, an atomizer/liquid reservoir portion comprising a liquid reservoir storing a liquid, and an atomizer adapted to atomize the liquid stored in the liquid reservoir when operated by the power supply. The atomizer extends away from the liquid reservoir in a first direction (L). The atomizer comprises first atomizer sections, wherein each of the first atomizer sections defines an opening that is at least partly encircled by the first atomizer section. The sizes of the openings defined by the first atomizer sections decrease with increasing distance of the first atomizer sections from the liquid reservoir in the first direction.

A dry powder aerosol delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The dry powder aerosol delivery device includes a housing, a cartridge, and a dry powder dispersion mechanism, and at least one differential pressure sensor. The dry powder delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The dry powder aerosol delivery device is then actuated to generate a plume of particles having an average ejected particle diameter within the respirable size range, e.g., less than about 5-6 μm, so as to target the pulmonary system of the user.
