Abstract: In this system we design an embedded patient monitor system for breath detection which monitor and records the patient’s breath, electrocardiograph and body temperature then it sends information to the PC. For ECG and temperature measurement electrodes and sensors are used. For the respiration rate measurement, we have used web cam. The image taken by the web cam is process using mat lab software and displayed on PC. If the breath rate is too low or too high or if stop more than 10sec our design system sends out an alarm signal. If the body temperature of the patents increases or decreases than the normal temperature, then the controller sends out an alarm signal. Likewise if pulse rate is too high or too low then it sends the signal to alarm.
