Nowadays the number of heart attack patients is increasing day by day. Though it is tough to
save heart attack patients we can increase the statistics of saving the lives of those
patients as well as the lives of those whom the heart attack patients are responsible for. The
main design of this project is to track heart attack patients suffering a heart attack during
driving send them medical help and stop the vehicle they are driving to ensure that the
persons along them are spared from accidents. An eye blinking sensor is used to monitor the eye
blinking rate and a spO2 sensor is used to check the pulse rate of the patient. Both are
connected to a micro controller. If eye blinking stops then the signal is sent to the
controller to make an alarm through the buffer. If the spO2 sensor perceives a variation in the
pulse rate or low oxygen content in the blood which may result in heart failure then the
controller stops the motor of the vehicle. Then a Tarang F4 transmitter is used to sent the
vehicle number and the mobile phone number of the patient to the nearest medical station within
25 km for medical aid. The pulse rate monitored via LCD .The Tarang F4 receiver acquires the
signal and passes through the controller the number gets displayed on the LCD screen and an
alarm is produced through a buzzer as soon the signal is received. Five topics are discussed in
this project: detecting the patient BPM and the eye blinking status transmitting via Tarang F4
in case of abnormalities in the patient the patient status is displayed and indicated by a
buzzer the hospital unit receives the patient's mobile phone number and car number and the
communication between the vehicle and the hospital through Tarang F4.
