Emergency Band (Em-Band)

Heart disease and blockage of blood vassel, especially coronary heart disease is the main cause of heart attack. Death due a heart attack often happens before the patient arrived to the hospital or a few minutes after a heart attack happens. The hearth attack is very difficult to known by people around the victim and can be known after the victim is passed away. Therefore to minimized the victim of late heart attack first aid treatment we made EmBand (emergency band) the bracelet that emits sos signal for people with heart disease. We expect emergency band can help people with heart disease as an emergency tools when heart attack ocurred or when the heart performance lower than usual to send emergency message to some relatives. The mothods that used in this activity are study of literature, system and design planning, also evaluation the success of the device. Based on the observation that had been done, the pulse sensor from the device have 70% accuracy from the real BPM that we compared with ECG. The first 30 seconds is the calibration phase of em band, and the next minute the device can detect pulse 70% accurate beat per minutes compared to the bpm from the ECG. Emergency band can be a medium for first aid for people with heart disease where it can send sos message to relatives when the heart beat in the danger condition.
