An additive gas delivery apparatus for delivery of additive gas to inspirational gas can be set to deliver the additive gas according to a dosing setting in normal therapy, and can be set to deliver according to a backup dosing setting in response disruption of signals representing data for controlling the delivery of additive gas according to the dosing setting in normal therapy. An additive gas delivery apparatus has an inlet for the additive gas and an integrated inlet for gas for oxygenating the patient that are connected to a backup line to mix the additive gas and gas for oxygenating the patient to a set concentration of additive gas in the gas mixture at an integrated backup outlet of the additive gas delivery apparatus.

Systems and methods are provided for detecting and sequestering waste anesthetic gases released by an anesthetic vaporizer. In one embodiment, a method for an anesthetic vaporizer installed in an anesthesia machine includes detecting an emission of waste anesthetic gases (WAGs) from the anesthetic vaporizer, and responsive to detecting the emission of WAGs, performing at least one of scavenging the WAGs and outputting an alert.

Disclosed are the unique and unexpected findings that xenon gas possesses the ability to directly inhibited amyloid beta associated toxicity, inhibit production of amyloid beta, and stimulate synthesis of soluble, free-form amyloid beta. The invention teaches the use of xenon gas, as well as various combinations of Noble Gases, for the prevention, amelioration, and treatment of Alzheimer's Disease and other pathologies associated with generation of insoluble aggregates containing amyloid beta.

An airway adaptor providing a measurement chamber for gas measurement by a mainstream gas analyzer includes a body having a first end and a second end and configured to connect in a ventilation circuit carrying ventilation gas to and from a patient. The body forms a primary path that includes the measurement chamber and is configured to allow ventilation gas to pass between the first end and the second end and at least one secondary path separated from the primary path and located on an outer perimeter of the primary path. The at least one secondary path is configured to contain liquid away from the measurement chamber.

The invention concerns a cartridge for an inhalation device for delivering anaesthetic to a human or animal wherein anaesthetic in the cartridge is dispersed in an anaesthetic control release medium; an inhalation device for use with the cartridge and a formulation including at least one selected anaesthetic and anaesthetic control release medium.

Start-up protocols for a device and method for administering NO is described.

Described are systems and methods for monitoring administration of nitric oxide (NO) to ex vivo fluids. Examples of such fluids include blood in extracorporeal membrane oxygenation (ECMO) circuits or perfusion fluids used for preserving ex vivo organs prior to transplanting in a recipient. The systems and methods described herein provide for administering nitric oxide to the fluid, monitoring nitric oxide or a nitric oxide marker in the fluid, and adjusting the nitric oxide administration.

The present invention pertains to a device (1) for ventilating a patient, including an invasive mechanical ventilator (2) for periodically providing a breathing gas to an invasive patient interface (20), wherein a gas injector (4) for injecting nitric oxide supplied by a source of nitric oxide (3) into the breathing gas supplied by the invasive mechanical ventilator (2) is provided.

A gas sensor for the detection of gases and vapors in air is particularly for the detection of anesthetic gases. A method for the detection and for the monitoring of such gases is also provided including detecting anesthetic gases with the gas sensor.

The present invention provides for systems and methods for inhaled CO therapy to prevent, attenuate, or delay processes that accelerate the loss of organ or tissue function, thereby increasing the lifespan of transplanted organs or tissues, or slowing the decline of native organs or tissues, or delaying the need for replacement of diseased native organs with organ transplants. Such biological processes that are prevented, attenuated, or delayed include chronic persistent inflammation, fibrosis, scarring, as well as immunologic or autoimmune attack.
