A ventilation device for artificially ventilating a patient, the controller of the ventilation device being designed to actuate a flow modifying device for carrying out a P/V maneuver, in which a patient is supplied with respiratory gas while the pressure of the respiratory gas is increased during an inspiration phase, said respiratory gas passively flowing out of the patient during an expiration phase after the pressure increase is terminated. For a plurality of respiratory gas pressures, the respective maneuver respiratory gas volume present in the patient as a result of the P/V maneuver is ascertained in connection with the present respiratory gas pressure during the inspiration phase as well as during the expiration phase; the controller is designed to—ascertaining a sequence of lung compliance values during the inspiration phase on the basis of signals of a flow sensor assembly and a pressure sensor assembly, —ascertain a reference compliance value in accordance with the sequence of compliance values, —on the basis of the reference compliance value, determine a termination compliance value, which differs from the reference compliance value in terms of amount, in the form of a threshold value as a termination criterion for the inspiration phase, and —terminate the inspiration phase if the termination compliance value is reached or exceeded.

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.

The present invention provides a method and apparatus for treating a subject suffering from obstructive sleep apnea (OSA). In one embodiment, the method of the present invention is configured to deliver negative airway pressure to a subject's airway to strengthen the airway muscle tone.

A respiratory treatment device includes a blower for providing flow of breathable gas to a patient and one or more accessory devices. The respiratory treatment device includes active power management to distribute power from a power source that does not have sufficient power to simultaneously power the blower and the accessory devices. The active power management prioritizes power to the blower and limits, based on current measurements of the blower and the accessory devices, the power supplied to the accessory devices to keep the sum of the power drawn at or below the capacity of the power supply. When additional power is available, due reduced power consumption of the blower, the power to one or more accessory devices is raised beyond a target in order to compensate for when power was not supplied to the one or more accessory devices.

The disclosed systems and methods provide a printed electronics breath indicator that may be directly printed or molded onto a manufactured breathing device, or separately attached to an existing breathing device. The printed electronics breath indicator may include an electroluminescent indicator, a sensor, and a processor. The processor may be configured to receive sensor data from the sensor, the sensor data including detected carbon dioxide (CO2) or oxygen (O2) levels. The processor may be further configured to determine a current breathing state of the patient based on the received sensor data. The processor may be further configured to cause the electroluminescent indicator to generate a visual representation according to the determined current breathing state of the patient. The visual representation may comprise a variable visual representation that displays one or more visual parameters that are proportional to the detected CO2 or O2 levels.

A method for preventing or treating an arrhythmia including administering an effective amount of hydrogen to a patient in need thereof.

An electronic vaporizer system includes an anesthetic sump containing anesthetic agent, a vaporizer unit that vaporizes the anesthetic agent from the sump and delivers the vaporized agent to a patient breathing circuit, and a gas sensor configured to measure end tidal concentration of the anesthetic agent and exhalation gasses from the patient. A control system is configured to receive the measured end tidal concentration of anesthetic agent and compare the measured end tidal concentration to a desired end tidal concentration to be maintained for the patient. The vaporizer unit is then automatically controlled to deliver an amount of vaporized agent to the patient based on the comparison.

Monitors for evaluating airway procedures, particularly in a pre-hospital environment, are described herein. In an example method, an airway parameter of an individual receiving assisted ventilation is detected by an airway sensor. A monitor determines a metric based on the airway sensor. Further, the monitor performs an action based on the metric.

This disclosure describes systems and methods for providing a high pressure controlled proportional assist ventilation breath type during ventilation of a patient. The disclosure describes a novel breath type that reduces ventilator support (or a percent support setting) based on the occurrence of a predetermined number of high pressure alarms.

An integrated oxygen supply device that is configured to generate oxygen continuously and release the oxygen non-continuously is provided. In some embodiments, the oxygen generated by the integrated oxygen supply device is stored in a porous material with the integrated oxygen supply device. The delivery of the oxygen produced by integrated oxygen supply device to a patient, in those embodiments, is controlled. In some embodiments, the control of the delivering oxygen is according one or more breathing patterns. The breathing pattern(s) may or may not be a current breathing pattern of the patient. For example, in one embodiment, the breathing pattern is a predetermined breathing pattern with a specified inspiration period followed by a specified expiration period.
