Pulse oxy cardio output measurement method, POCO-2

Abstract

To enable safe, simple and accurate measurement by replacing a conventional invasive CO measurement method by a non-invasive measurement method.SOLUTION: A triangulation method of a cardiac output is acquired by adding a pulse frequency to blood oxygen saturation, SpO2. A POCO-2 method uses the inverse of SpO2xpulse on the horizontal axis of a graph instead of the pulse standardization used in the POCO method part 1. This is a method of setting a ruler of triangulation, in which a difference in results is divided by a difference in causes, and a result is analyzed by working backwards from the causes. Mathematically, it has been clarified by the above calculation example, whereby cardiopulmonary dynamics can be measured non-invasively, and the synergistic effect of data accumulation (an effect of data becoming a next standard) enables further accurate measurements.SELECTED DRAWING: None

Description

[Technical field]

[0001] Controlled medical device, medical diagnostics to measure total cardiopulmonary function. [Background technology]

[0002] The proposed POCO method is a method of setting the scale and software for measuring cardiac output using a pulse oximeter, which has been a huge hit worldwide. As the saying goes, "amateur ideas, professionals put them into practical use," professionals can be trapped in their own specialized knowledge and miss the mark on things that are right in front of them. In fact, even the pros who invented the pulse oximeter are unaware of this measurement method. The patent application proposals under Part 1 of the POCO Act were all submitted to many PHR-related manufacturers via registered mail, with the understanding that "it is up to the manufacturer's discretion whether to patent or make the information public," and evidence of this was secured. Some manufacturers have said, "Due to company circumstances, we cannot cooperate with patent requests from outsiders..." As a result, I decided to rename POCO Method Part 1 to POCO Method 2, add formulas to it, and apply for a patent in my personal name.

[0004] By replacing conventional invasive measurement methods with non-invasive methods, safe, simple, and accurate measurements are possible. [Means for solving the problem]

[0005] Pulse, blood oxygen saturation SpO2 and cardiac output, CO There is a correlation with. This method measures CO on a graph line standardized by body weight, with CO for subjects A and B, whose Pulse, SpO2 and CO are known, plotted on the vertical axis and the inverse of SpO2 x Pulse on the horizontal axis. If we know CO, then we know Ohm's Law This is possible with V = IR Blood pressure = cardiac output x pulse rate. The POCO method is a commercially available pulse oximeter that measures the most important vital signs. This is a patent application proposal for software and know-how that can accurately and easily measure signs and cardiopulmonary function at the fingertips or wrist.

[0006] Mechanism of cardiac output measurement using POCO-2 (Pulse Oxy Cardio Output) CO and Pulse are proportional, but CO and SpO2 are inversely proportional, so this can be represented on a graph as shown below. [Table 1] [Table 2] Effect of the Invention

[0007] Unlike conventional invasive measurement methods, this method only requires placing a sensor on the fingertip or wrist to measure blood oxygen saturation (SOO2) and pulse rate, so there is no physical or mental burden on the subject or patient. Furthermore, it can simultaneously measure not only cardiac output (CO) but also comprehensive cardiopulmonary dynamics in a multifaceted, non-invasive manner, making it possible to provide safe and simple medical diagnosis. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] This will require clinical verification and setting of correction values. "Measurement items" 1. Cardiac function, cardiac output, CO2, pulmonary function, SpO2 / CO 3. Continuous cardiopulmonary function measurement 4. Blood pressure 5. Other related data When combined, new diagnoses can be generatively made.
