Understanding Your Blood Pressure Numbers

If you've ever stared at a blood pressure reading like 128/82 and wondered what it actually tells you, you're not alone. Understanding these two numbers is one of the most useful health skills you can build — especially because high blood pressure usually has no symptoms at all.

The two numbers, explained

Systolic pressure (the top number) is the pressure in your arteries when your heart beats and pushes blood out. Diastolic pressure (the bottom number) is the pressure when your heart rests between beats. Both are measured in millimetres of mercury (mmHg).

What's considered normal?

Hypertension Canada uses these general categories for readings taken at home:

• Normal: below 135/85 (at home; 140/90 in clinic)
• High blood pressure: 135/85 or higher on repeated home readings
• Talk to your provider promptly: readings consistently at or above 180/110, or any very high reading with symptoms like chest pain, shortness of breath, or vision changes — seek urgent care

Targets can differ if you live with diabetes, kidney disease, or other conditions, so always confirm your personal target with your healthcare provider.

Why one high reading isn't a diagnosis

Blood pressure naturally rises and falls through the day. Stress, caffeine, a full bladder, even talking during the measurement can push numbers up temporarily. That's why guidelines recommend looking at the average of multiple readings over several days rather than reacting to a single result. Many home monitors, including Path Pharm's, automatically average your recent readings for this reason.

Tracking at home pays off

Research consistently shows that people who monitor at home are more likely to reach their blood pressure targets. A regular routine — same time each day, seated and rested — gives your healthcare provider far more useful data than a single annual clinic reading.
