2. Abstract
Limb blood as a flow permanent flow per beat and the volume of cardiac output
Safe method
Non-reactive
Advance analog amplifier
Microprocessor controller
Flexible output signal
3. Material and Methods:
It is depend upon 3 blocks:
Microcontroller
Acquisition circuit
Processing block
4. Periodic current signal to the body part
Develop a pulse tile impedance variable of the tissue
5. MSP430
Ultra low power
Combine controller and flexible clock signal
16 bit wide
Inter changeably
Similar like 8 bit
7. Result
Calculate algorithm by using MATLAB
20 clinical volunteers
Community of the ethics
Calculate limb blood parameter flow per beat and measure in percentage
Average over 6 heartbeats
