Q
What is the bene
fi
t of measuring my blood pressure at home?
A
Blood pressure measurements taken at home give reliable data as they can be
taken when you are in a stable and relaxed condition. Physicians place considerable
importance on blood pressure measurements taken at home. You should measure
your blood pressure at the same time each day and record the variations in your blood
pressure.
Always consult your physician for an interpretation of your blood pressure
readings and to determine the proper treatment.
