Blood pressure measurementBlood pressure measurement
Blood pressure:
is defined as the intra-arterial pressure generated by
the pulsatic flow of blood through an artery. The blood pressure is indicated from two numbers.
Systolic:represents the pressure while the heart is beating.
maximum value for blood pressure
Diastolic: represents the pressure when the heart is resting between beats.

DemonstrationDemonstration
Measure current temperature and blood pressure and display it on the palm.
Display temperature,blood pressure and ECG wave in Hyper terminal, then take the data and save it in a file. Finally display it on java applet.
