A system for generating nitric oxide can include an apparatus positioned in a trachea of a mammal, the apparatus including a respiration sensor for collecting information related to one or more triggering events associated with the trachea, an oxygen sensor for collecting information related to a concentration of oxygen in a gas, and one or more pairs of electrodes for initiating a series of electric arcs to generate nitric oxide, and the system for generating nitric oxide can also include a controller for determining one or more control parameters based on the information collected by the respiration sensor and the oxygen sensor, wherein the series of electric arcs is initiated based on the control parameters determined by the controller.

A pressure support system configured to provide pressure support therapy to a subject is described. The pressure support system comprises a humidifier configured to control the humidity of gas provided to the subject during a sleep cycle to ensure an amount of liquid will remain in the humidifier at the conclusion of an estimated usage time. The pressure support system is configured to ensure humidified breathing gas is delivered to a subject during a usage time within a pressure support usage period. During times when the subject's moisture demand is greater than amount of moisture available in the humidifier, the pressure support system may decrease the amount moisture in the breathing gas so humidified therapy is available during the entire time the user is asleep.

In some additional aspects, an apparatus can include a chamber having an inlet valve for receiving a reactant gas and an outlet valve for delivering a product gas, a piston positioned inside the chamber and configured to move along a length of the chamber for adjusting pressure in the chamber, a sensor for collecting information related to one or more conditions of a respiratory system associated with a patient, a controller for determining one or more control parameters based on the collected information, and one or more pairs of electrodes positioned inside the chamber for initiating a series of electric arcs external to the patient to generate nitric oxide based on the determined control parameters.

The present disclosure pertains to a ventilation therapy system configured to control a pressure or flow generator to apply an intra-pulmonary percussive ventilation therapy regime to a pressurized flow of breathable gas during baseline ventilation therapy. The ventilation therapy system is configured to automatically control the pressurized flow of breathable gas. The system may automatically control an extent of hyperinflation during IPPV in a subject. The system is configured such that therapy set points, alarm settings, and/or other factors are automatically adjusted during the application of IPPV relative to the set points and alarm settings during baseline ventilation therapy. In some embodiments, the system comprises one or more of a pressure or flow generator, a subject interface, one or more sensors, one or more processors, a user interface, electronic storage, and/or other components.

Embodiments of the present invention provide systems and methods for delivering respiratory treatment to a patient. For example, a treatment system may include a mechanism for delivering a positive pressure breath to a patient, and one or more limb flow control assemblies which modulate gas flow to and from the patient. Exemplary treatment techniques are embodied in anesthesia machines, mechanical ventilators, and manual ventilators.

An anesthesia ventilator, for the automated ventilation of a patient, includes an expiratory port and an inspiratory port for connecting a ventilation tube facing the patient for a breathing gas, a breathing gas delivery unit, at least one breathing gas sensor for detecting an anesthetic gas concentration, at least one pressure sensor for detecting a pressure of the breathing gas, as well as at least one computer. The computer is configured to actuate the breathing gas delivery unit as a function of the detected pressure of a preset desired pressure value. The computer is further configured to perform an adaptation of the desired pressure value as a function of the detected anesthetic gas concentration.

An emergency ventilation system ventilates a patient and includes a chamber housing defining a breathing chamber; a piston; and a motor operably connected to the piston. The motor applies an exhalation force to move the piston in an exhalation direction applies an inhalation force to move the piston in an inhalation direction. The piston increases air in the breathing chamber as the exhalation force is applied and decreases air in the breathing chamber as the inhalation force is applied. An exhalation check valve allows airflow from the air source to the breathing chamber and not to allow airflow from the breathing chamber to the air source as the inhalation force is applied. An inhalation check valve allows airflow from the breathing chamber to the air output and not to allow airflow from the air output to the breathing chamber as the exhalation force is applied.

An anesthesia ventilator, for the automated ventilation of a patient, includes an expiratory port and an inspiratory port for connecting a patient ventilation tube for a breathing gas, a breathing gas delivery unit, a breathing gas volume flow sensor, a breathing gas sensor for detecting a carbon dioxide concentration, a pressure sensor for detecting a pressure of the breathing gas, and a computer. The computer is configured to actuate the breathing gas delivery unit in a first mode of operation as a function of a preset ventilation rate, of the detected pressure and of a preset desired pressure value. The computer is configured to detect the presence of a desired operating state concerning the automated ventilation on the basis of the detected volume flow and of the detected carbon dioxide concentration and to make possible a transition to a second mode of operation in case of detection.
