Why home readings help
Office blood pressure can rise from stress (“white coat” effect). Home averages often reflect true control better and guide medication changes safely—endorsed in Canadian hypertension guidance from Hypertension Canada.
Choose the right cuff
Use a validated upper-arm device with the correct bladder size for your arm circumference. Wrist cuffs are less reliable unless arm measurement is impossible.
Technique matters
Rest five minutes; feet flat; back supported; arm at heart level; no talking; empty bladder beforehand. Take two readings one minute apart, morning and evening for a week when your clinician asks for a log.
Share structured logs
Bring averages—not single highs—to review. Note medication timing and caffeine/exercise.
When to seek urgent care
Blood pressure extremely high with chest pain, neurologic deficits, severe headache, or shortness of breath needs emergency assessment. Asymptomatic mild elevations can usually be managed by message or next-day visit—ask your team for your personalized thresholds.
