<s>[INST] my dad is 81 years old - and is in bed the last five years. these days it's pretty hot and is out of ordinary - like very quiet - i have the pressure machine at home and it read 221/90 i gave him extra micardis for his pressure which he usually gets in the mornings... do i have to call the doctor? i don't know  how this system works - if free or with pay... [/INST] Hello.  Yes his doctor needs to know about this since that level of hypertension is very dangerous and your trying to treat it at home with more micardis is simply not the best way to deal with the problem </s>
