Why Home Monitoring Matters
Knowing your numbers helps prevent serious health conditions like:
- Heart attacks and strokes
- Kidney disease
- Dementia
- Pregnancy complications
By using a BIHS-approved monitor, you’re taking a vital step in managing your health and preventing chronic illness.
Monitor Life and Recalibration
There is evidence that the accuracy of automated BP monitors degrades over time. As a result, manufacturers recommend regular recalibration of monitors. However, this can be inconvenient and expensive for individuals who have bought a home monitor for personal use.
For monitors used in clinical environments (including hospitals, GP surgeries and pharmacies), the manufacturers’ instructions for monitors should be followed. Formal recalibration annually should be regarded as a minimum.
For home monitors, real world evidence1 suggests that monitors should be replaced after a maximum of four years of use with a suitably validated replacement. However, they should be replaced sooner if there is evidence of damage, particularly to the cuff, or concern about accuracy.
