My father has low blood pressure so that he had got some accidents due to weakness and fainting. Last night he has fallen down from stairs. He wasn't able to call anybody so that he spent the whole night on the floor, unable to get up, until I found him in the morning. Doctor has advised me to wear him a Medical alert system for his security. But I want to take some more securities for him. How can we protect him any time? Do you have any idea about it? If you have, then please do convey it. It will be great relief to me.
