摘要:
Embodiments of the present invention include a system and method for monitoring the ventilation support provided by a ventilator (20) that is supplying a breathing gas to a patient (p) via a breathing circuit (22) that is in fluid communication with the lungs of the patient (p). The ventilator (20) has a plurality of selectable ventilator setting controls (30) governing the supply of ventilation from the ventilator (20), each setting control (30) selectable to a level setting. The ventilator support monitor system (10) preferably receives at least one ventilator setting parameter signal (42), each ventilator setting parameter signal (42) indicative of the level settings of one ventilator setting control (30), monitors a plurality of sensors (52-58), each sensor (52-58) producing an output signal (51) indicative of a measured ventilation support parameter, to determine the sufficiency of the ventilation support received by the patient (p), and determines the desired level settings of the ventilator setting controls (30) in response to the received ventilator setting parameter signal (42) and the output signals (51). The ventilator support monitor system (10) preferably utilizes a trainable neural network (82) to determine the desired level settings of the ventilator setting controls (30).
摘要:
A method and apparatus for operating a ventilator in a primary electronic mode or in a back-up pneumatic mode during primary electronic mode failure. A method and apparatus for operating a ventilator in an advanced mode, having a number of ventilatory modes, or in a basic mode, having a limited number of ventilatory modes is also disclosed. A method and apparatus for controlling a ventilator is disclosed wherein the body length of a patient to be ventilated is utilized in determining one or more ventilation parameters. Ventilation limits and alarm settings are also determined in accordance with body length. A method and apparatus is also disclosed for selecting a rate of rise of inspiratory pressure.
摘要:
A method for estimating effort of breathing of a patient, comprises: receiving respiratory parameters of the patient; calculating, with a processor, respiratory data from the respiratory parameters; inputting the respiratory data into a mathematical model created using clinical data; and providing at least one output variable from the mathematical model corresponding to effort of breathing; wherein the mathematical model is trained to provide said at least one output variable, wherein the training of the mathematical model comprises use of esophageal pressure from a test population of patients as clinical data input to the mathematical model.

摘要:
Disclosed herein are methods and devices of obtaining plethysmograph readings and utilizing plethysomography to identify when pilots are about to experience GLOC. Furthermore, in other embodiments, the invention pertains to methods and devices designed to warn a pilot that he/she is about to enter GLOC and/or automatically averting catastrophic damage or injuries by directing a plane being piloted to take predetermined corrective actions. Specifically disclosed is a system embodiment for assisting in the prevention of gravity induced loss of consciousness. The system comprises at least one pulse oximeter probe 10 configured for securing to a central source site of a pilot and to generate signals indicative of blood flow at said central source site, an analyzer unit 58 communicatingly connected to said at least one pulse oximeter probe 10, said analyzer unit comprising at least one processing module 56 configured to determine whether said blood flow is approaching a predefined level, and an aircraft computer 51 communicatingly connected to said analyzer unit 58, said aircraft computer 51 comprising at least one processing module 59 configured to effect a predetermined reaction responsive to said blood flow falling below a predetermined level.
