Abstract: In one embodiment, a method for determining patient response to an extubation procedure from a mechanical ventilator is disclosed. The method includes receiving one or more physiologic, pulmonary mechanism or oxygenation-related parameters measurements for a predetermined period of time and retrieving a known data set. A first extubation index is calculated with the physiologic, pulmonary mechanism measurements or oxygenation-related parameters and compared with the known data set. An assessment is produced concerning utilization of a device after extubation.

Abstract: In one embodiment, a method for categorizing a state of a subject undergoing therapy from a mechanical ventilator is disclosed. The method includes receiving, at a device, one or more cardiovascular measurements regarding the subject, a respiratory rate from the ventilator, a carbon dioxide (CO2) measurement regarding the subject, and a tidal volume value from the ventilator. The method also includes selecting, by the device, a ventilation category based on the one or more cardiovascular measurements, the respiratory rate, the CO2 measurement, and the tidal volume value. The method further includes retrieving, by the device, an alert that is associated with the selected ventilation category. The method additionally includes providing, by the device, the alert to a user interface device.

Abstract: A method and system that provides for minute-to-minute EBC pH monitoring (or for other EBC characteristic monitoring) of a subject that greatly assists in determining the time-course of airway pH changes (or other characteristic changes) in evolving disease processes, and may assist in determining the predictive ability of these tests, as well as determining response to therapy.
