Embodiment Construction

[0016] The invention will now be described with reference to the drawings, in which like reference numerals indicate like parts.

[0017] figure 1 is a block diagram of an automated oxygen delivery system according to one embodiment of the invention. In general, the automated oxygen delivery system 100 is a software-driven servo-controlled gas delivery system that provides ventilation of various volumes and pressures to neonatal, pediatric, and adult patients. More specifically, the automated oxygen delivery system 100 safely maintains the measured oxygen level in the patient's bloodstream within a range selectable by the user by titrating FiO2 based on the oxygen measurement. Such as figure 1 As shown, an automated oxygen delivery system 100 includes a sensor 10 for measuring the oxygen content in a patient's bloodstream, a control subsystem 20 , and a pneumatic subsystem 30 .

[0018] In a preferred embodiment, sensor 10 is a Masimo Signal Extraction pulse oximeter sensor...

Abstract

The present invention advantageously provides a system for automatically delivering oxygen to a patient, including a sensor to measure an amount of oxygen in a bloodstream of a patient, a pneumatics subsystem (30) and a control subsystem (20). The pneumatics subsystem includes an oxygen inlet (36), an air inlet (37), a gas mixture outlet (38), and a gas delivery mechanism to blend the oxygen and air to form a gas mixture having a delivered oxygen concentration, and to deliver the gas mixture to the patient. The control subsystem includes an input device to receive a desired concentration of oxygen in the bloodstream of the patient, a sensor interface (14) to receive measurement data and status information associated with the measurement data from the sensor (10), a pneumatics subsystem interface (34) to send commands to, and receive data from, the pneumatics subsystem, and a processor (22) to control the delivered oxygen concentration based on the desired oxygen concentration, the measurement data and the status information.

Description

technical field [0001] The present invention generally relates to oxygen delivery systems and methods. More specifically, the present invention relates to an automated oxygen delivery system. Background technique [0002] Many patients require respiratory support including supplemental oxygen and / or assisted ventilation. Babies, especially those born prematurely, may not be able to maintain adequate breathing and require support in the form of a breathing gas mixture combined with ventilation assistance. The breathing gas mixture has an increased fraction of oxygen (FiO2) compared to room air, and ventilation assistance provides an elevated air pressure in the upper airway. A large number of infants receiving respiratory support will exhibit a period of desaturation, a period in which insufficient oxygen is absorbed in the lungs and oxygen saturation decreases. These periods may occur as frequently as twenty times an hour, and each period must be carefully managed by the ...
