But if you besides take symptoms like dizziness and nausea, information technology could be a sign that your blood pressure is as well low for good health.
Measuring Claret Pressure
A cuff linked to a special device tightens around your arm to go two measurements. The meridian number, or "systolic," notes the pressure your blood makes against your avenue walls when the heart beats.
