If you systolic (top number) bp is greater than 180 and/or diastolic (bottom number) is greater than 110 you should seek emergency care.

Blood pressure
The patient's blood pressure had reached critical levels.
normal blood pressure reading
The normal blood pressure is usually between 120-140 mm Hg (systolic) and 80 - 90 mm Hg (diastolic). Anything higher will be considered as high blood pressure
Second
Systolic (the higher number) is a reading of the pressure in your blood vessels when your heart is beating at its maximum strength. Diastolic (the lower number) tells you what the pressure is in your blood vessels when your heart is at rest.
Because blood pressure changes.
A blood pressure reading consists of two numbers: systolic pressure (the top number) and diastolic pressure (the bottom number). The systolic pressure measures the pressure in the arteries when the heart beats, while the diastolic pressure measures the pressure in the arteries when the heart is at rest between beats. The third number, if present, is the pulse pressure, calculated by subtracting the diastolic pressure from the systolic pressure. This number gives an indication of the force the heart generates with each contraction.
