On decreasing blood pressure for hypertension patients:
Blood pressure of normal and healthy adults is 120/80. But
when a person has hypertension, his blood pressure must be
decreased gradually, not down to 120/80 immediately.
The term 'gradually' is defined as to decrease in systolic
blood pressure no more than 20 mm Hg within 2 hours. For
instance, if a person's systolic blood pressure is 200 mm
Hg, the goal for the first two hours is to decrease it to
180, not 120. Then the goal for second two hours is 160, and
so on. Decreasing blood pressure too fast may cause syncope,
falls, dizziness, weakness, angina pectoris, or stroke.
Therefore, the doctor should not increase dose of medicine
because a patient's blood pressure is higher than another.
For instance, he should give same dose to patients with
systolic blood pressures of 240, 220, 200 and 180, because
his goal is to invariably decrease 20 mm Hg for each patient
within 2 hours.
He only increases the dose when having found a patient's
blood pressure has decreased too little after some time.
