<s>[INST] My Father in  Law is 82 years old he had high blood pressure when we visited the dr. a week ago 190 over something.  anyway he gave him medication and yesterday went for a heart stress test, the blood pressure has not gone down.  They did not say anything yesterday as it still should of been high.  This morn. again it was 191 over 108, I took it 3 different time the lowest reading was 188 over 96, I check mind to be sure the monitor was working and I was 122 over 72, should I be concerned and take him back to a doctor today???? [/INST] Hi you should take him back to the cardiologist and blood pressure should be taken manually three times at an interval of 10 minutes, an average of 3 readings should be considered as his blood pressure and please do write your question clearly, I check mind to be sure the monitor was working, and I was 122 over 72, I cant understand the meaning of this line, still stress test would be done only when blood pressure is below 140/90. Hence you should take recording manually over two hands three times separated by an interval of 10 minutes, </s>
