Abstract
Systems, methods, and computer-readable media for providing a decision support solution to medical professionals to optimize medical care through data monitoring and feedback treatment are provided herein. In another embodiment, a computer-implemented method for modeling patient outcomes resulting from treatment in a specific medical area includes receiving patient-specific data associated with a patient, determining a plurality of possible patient states under which the patient can be categorized, a current patient state under which the patient can be categorized and determining probabilities of the patient transitioning from any of the possible patient states to every other possible patient state.
Core Innovation
The invention relates to a decision-support system for event driven patient monitoring and treatment that uses a plurality of physiological sensors to produce patient-specific data and a processor to determine physiological variables, including at least oxygen saturation. A state space is defined using DO2 on a first axis and Qp/Qs on a second axis, with the state space partitioned into a plurality of possible clinical patient states using explicit boundaries.
The invention determines a current clinical patient state within the state space from the patient-specific data and sends a signal to a treatment device so the treatment device administers a treatment known to address the current clinical patient state. The state space includes patient states that combine adequate versus inadequate DO2 with normal versus high Qp/Qs, and defines boundary values that distinguish those conditions.
The boundary between adequate DO2 and inadequate DO2 is 25 ml O2/min/kg, and the boundary between normal Qp/Qs and high Qp/Qs is a ratio of 1.5. The patient state of adequate DO2 along with high Qp/Qs is defined by DO2 greater than 25 ml O2/min/kg along with Qp/Qs greater than a ratio of 1.5, inadequate DO2 along with high Qp/Qs is defined by DO2 less than 25 ml O2/min/kg along with Qp/Qs greater than a ratio of 1.5, and inadequate DO2 along with normal Qp/Qs is defined by DO2 less than 25 ml O2/min/kg along with Qp/Qs less than a ratio of 1.5.
Claims Coverage
The partial content provides three independent claim categories: a system claim, a method claim, and a computer-readable medium claim. Across these independent claims, the inventive features center on defining a DO2/Qp/Qs state space with quantitative boundaries, determining a current clinical patient state, and signaling a treatment device to administer a treatment known to address that state.
Event driven patient monitoring with sensor-to-state determination
A system for event driven patient monitoring and treatment comprising a plurality of physiological sensors including at least a blood oximeter configured to produce patient-specific data, and a processor that receives patient-specific data, determines physiological variables including at least oxygen saturation, defines a state space with DO2 on a first axis and Qp/Qs on a second axis, and determines a current clinical patient state within the state space.
DO2/Qp/Qs clinical state space with explicit boundaries
Defining a state space with DO2 on a first axis and Qp/Qs on a second axis, the state space partitioned into a plurality of possible clinical patient states defined by a plurality of boundaries, including a boundary between adequate DO2 and inadequate DO2 and a boundary between normal Qp/Qs and high Qp/Qs, wherein the boundary between adequate DO2 and inadequate DO2 is 25 ml O2/min/kg and the boundary between normal Qp/Qs and high Qp/Qs is a ratio of 1.5.
State-based signaling to treatment device
Sending a signal to the treatment device coupled to the patient so that the signal causes the treatment device to administer a treatment to the patient, the treatment known to address the current clinical patient state.
Computer-implemented method for state-based treatment
A method for event driven patient monitoring and treatment comprising coupling physiological sensors including at least a blood oximeter to the patient, receiving patient-specific data at a computer, determining physiological variables, defining a DO2/Qp/Qs state space with quantitative boundaries, determining a current clinical patient state within the state space, and sending a signal from the computer to the treatment device so that the treatment device administers a treatment known to address the current clinical patient state.
Non-transitory computer-readable medium for state-based treatment
A non-transitory computer-readable medium having computer-executable instructions comprising instructions to cause a computer to receive patient-specific data including at least data from a blood oximeter, determine physiological variables including at least oxygen saturation, define a DO2/Qp/Qs state space with boundaries wherein the boundary between adequate DO2 and inadequate DO2 is 25 ml O2/min/kg and the boundary between normal Qp/Qs and high Qp/Qs is a ratio of 1.5, determine a current clinical patient state within the state space, and control a treatment device by sending a signal so that the treatment device administers a treatment known to address the current clinical patient state.
Across the independent claims, the coverage is concentrated on sensor-derived patient-specific data, defining a DO2/Qp/Qs clinical state space partitioned by quantitative boundaries, determining the current clinical patient state from the physiological variables, and signaling a treatment device so that a treatment known to address that current clinical patient state is administered.
