METHOD, DEVICE AND SYSTEM FOR DETERMINING A SHIFT IN CARDIAC OUTPUT
EP3906847
The invention relates to a method, device and system for determining a shift in cardiac output from a first plethysmographic signal in a first span of time in which at least one first period of time is included during which an output pressure measurement has been applied to the user that is higher than venous pressure and lower than systolic pressure, and a second plethysmographic signal in a second span of time, some time after the first span of time, in which at least one second period of time is included during which an output pressure measurement has been applied to the user that is higher than venous pressure and lower than systolic pressure.
A portable device, superior in simplicity of manufacture and maintenance, with a more contained associated cost, as well as a procedure for determining the trend of cardiac output that does not require a high computational capacity so that the procedure is easy to execute. and the device can be accessible to a greater number of users.
