Abstract: System and methods for detecting precursors of VAP in a patient being ventilated. An exemplary method comprises obtaining a baseline value for a content of a particular VOC in tVOCs in exhaled breath of the patient being ventilated, trending changes of values of the content of the particular VOC in the tVOCs measured at various points of time after ventilation compared to the baseline value, determining whether the patient has potentially infected VAP based at least in part on the trending, and in response to determining that the patient has potentially infected the VAP, generating an alert.

Abstract: Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, a system includes an anesthetic agent reservoir, a pump fluidically coupled to the agent reservoir, an injector configured to receive pressurized anesthetic agent from the pump, a vaporizer comprising a heated chamber configured to receive and vaporize the anesthetic agent injected by the injector and supply a mix of the vaporized anesthetic agent and medical gas to a subject via a supply line, and a controller. The controller stores instructions executable to determine a concentration of the vaporized anesthetic agent in the mix and adjust one or more injector parameters based on a difference between the concentration of the vaporized anesthetic agent and a commanded concentration.

Abstract: Methods and systems are provided for anesthesia systems for heart-lung machines. In one embodiment, a system comprises: a cardiopulmonary bypass machine; and an anesthesia machine operably coupled to the cardiopulmonary bypass machine, the anesthesia machine adapted to control a flow of vapor through the cardiopulmonary bypass machine.

Abstract: Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, a liquid anesthetic agent container includes a base region, an interior of the base region configured to hold liquid anesthetic agent, an adapter region, and a capillary force vaporizer (CFV) housed in the adapter region. The adapter region includes a coupling end configured to couple to a patient breathing circuit to supply anesthetic agent vaporized by the CFV to a patient.

Abstract: In the present invention, a device, system and associated method is provided, as a compact, automated and self-contained data logger with capability of withstanding conditions used in sterilizing reusable medical device equipment/components. The device includes one or more sensors to automatically sense and store information on the parameters of various autoclave cycle(s) for the component associated with the tracking device and their respective timestamps of each autoclave cycle(s). This information is stored in a data record on the tracking device for the individual component. The data record can be used as evidence of valid sterilization cycles for the component and can also provide information for the host system and/or the user of the status for the component, including the last time the component was sterilized, the time between sterilization cycles, the time for replacement of the component, and too warn if the device was returned to service without proper sterilization.

Abstract: A method of ventilating a patient is provided. The method comprises measuring a patient physiological parameter while the patient is in a first position and recording the measured patient physiological parameter as a baseline. The method further comprises tilting the patient from the first position to a second position and measuring the patient physiological parameter when the patient is in the second position. The method further comprises performing an action based on a change in the measured physiological parameter from the baseline when the patient is in the second position. The action is at least one of modifying a ventilation parameter, generating an alert, and providing a recommendation.

Abstract: The system and method of the present application includes an image guided radiation therapy (IGRT) system, combined with a medical ventilator, to form a closed-loop system to optimize treatment of a tumor for patients who cannot comply with a normal respiratory management procedure. The ventilator may be used to generate respiratory maneuvers to facilitate clean images for dose planning, so that clinicians can more clearly visualize a target with fewer of the image artifacts associated with respiratory motion. The combined IGRT and ventilation systems approach facilitates treatment of specific organs most susceptible to respiratory motion artifact, and helps minimize the doses to the heart in left-breast treatments. Improved positioning of the anatomical target structures for exposure to external beam radiation may be accomplished through combinations of respiratory-gating, respiratory pause, and selective right or left lung mechanical ventilator techniques.
