The Anna University scientists have developed an (AED) automated external defibrillator, a portable device utilized to bring back the heart rhythm, which can be handled using Tamil, Hindi, besides English. This will permit even an illiterate without medical training to help a heart attack victim as the AED operates on voice commands. The use of Tamil and Hindi is one of the major value additions by the Anna University team, which plans to other languages also.
“The low-cost machine developed by us can be deployed at railway stations, bus stops to prevent deaths due to a heart attack. Being GPS-enabled, the machine can automatically select the language based on the location”, said a professors T Thyagarajan of Madras Institute of Technology and Principal investigator of the project.
When the device is switched on the machine asks to choose the language. Then it will you set the adhesive pads on the chest of the collapsed person to study the heart rhythm. If the rhythm is abnormal, it will ask you to step away and administer shock was as needed.
Co-principal investigator Sabitha Ramakrishnan at the department of instrumentation, Madras Institute of Technology Chrompet. “The device will restore a normal heartbeat by sending an electric shock to the heart. They are used to prevent or current arrhythmia- uneven heartbeat. It can also restore heartbeat if it suddenly stops”.
The cost of AED is nearly Rs 1.5 lakh while the prototype developed by Anna University researchers cost just Rs, 50,000. The commercial production of the machine will commence within a year, Scientists stated. Airports and some shopping malls have imported from use it needs.
Dr. K Kannan, a senior consultant cardiologist in the city, stated AED were useful in cases of a heart attack outside of hospitals. Although the correctness of the device must be 100% and it should be properly validated, he said.
