11. Blood 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.

20. Demonstration  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.

21. Conclusion The Palm pilot is not only an organizer, but also a device to monitor data(Blood pressure, Temperature)
