"Let's discuss home blood pressure monitoring. How do we ensure patients get the best readings? Preparation, arm position, and other small factors can change your BP reading by 10% or more," Dr Danielle explained in her post. Here's everything she recommends:
How to choose the right device
- Use a brachial (upper arm) cuff – it's more accurate than wrist cuffs.
- Avoid manual (auscultatory) devices unless you're trained; automated monitors are more reliable for at-home use.
- Get a monitor with memory – look for a device that stores your readings or connects to your phone via Bluetooth.
- Cuff size matters – make sure the cuff fits your arm correctly for accurate readings.
- Verify your device – take it to your doctor's clinic or pharmacy to compare its readings with their equipment.
Before you check your BP
- Avoid smoking, caffeine, or exercise 30 minutes before.
- Rest quietly for 5 minutes before measuring.
Sit correctly
- Sit with your back straight and supported.
- Keep feet flat on the ground, legs uncrossed.
- Rest your arm on a flat surface, keeping the upper arm at heart level.
How and when to take readings
- Place the cuff on your bare upper arm, about an inch above your elbow crease.
- Take at least two readings, one minute apart.
- Measure once in the morning (before medications) and once at night (before dinner).
- Track your BP daily, or even twice a day if advised.
Bring your device and readings to your doctor
- This helps your doctor make more accurate treatment decisions.
- It also helps distinguish between true hypertension, masked hypertension, and white coat hypertension.
