Hi, My husband is 73 years old, diagnosed with congestive heart failure in August, and for the past 3 days has had a bad chest cold and cough and is in bed. I have been monitoring his weight, blood sugars, and blood pressure/pulse. He has been fairly consistent with readings in low 100/65, but just checked him and he is 140/78, pulse 77. All he did was walk from the chair to the bedroom to lie down again. At what point do I take him to the hospital. How high should his blood pressure get? Thank you so much.
