Abstract
Non-invasive sensor apparatus and method for assessing cardiac performance. A wide variety of different sensor components can capture sensor readings relating to patient attributes. Those sensor readings can then be compared by a processor component to derive a cardiac performance indicator relating to the patient.
Claims20
An apparatus for detecting a cardiac performance indicator that relates to a patient with a plurality of locations, including a first location and a second location, said apparatus comprising:
- a plurality of sensor components positioned at the plurality of locations, said plurality of sensor components providing for the capture of a plurality of sensor readings, said plurality of sensor components including a first sensor component and a second sensor component, said plurality of sensor readings including a first sensor reading and a second sensor reading, wherein said first sensor reading is captured by said first sensor component at the first location, and wherein said second sensor reading is captured by said second sensor component at the second location;
- and
- a processor component that provides for receiving said plurality of sensor readings and selectively identifying the cardiac performance indicator by comparing said sensor readings.
A method for detecting a cardiac performance indicator that relates to a patient, comprising:
- using a plurality of sensor components positioned at a plurality of locations on the skin of the patient to capture a plurality of sensor readings;
- using a processor component to compare said plurality of sensor readings;
- and
- using the processor component to identify the cardiac performance indicator from the comparison of sensor readings.
A method for detecting a cardiac performance indicator that relates to a patient, comprising:
- positioning a sensor strip that includes a plurality of skin temperature sensor components on a first appendage of the patient from a core location to an extremity location;
- capturing a first set of skin temperature readings pertaining to the first appendage of the patient;
- displaying the first set of skin temperature readings as a first gradient;
- and
- calculating a systemic vascular resistance value and a cardiac output estimate using said first gradient;
- wherein said cardiac performance indicator is said cardiac output estimate.
