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.
• Systolicrepresents the pressure while the heart
  is beating. maximum value for blood pressure
• Diastolic represents the pressure when the
  heart is resting between beats.

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.

Conclusion

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