Technical aspects of BP measurement |
Measure BP: |
|
• No tobacco or caffeine for 30 minutes preceding measurement |
|
• After 5 minutes rest |
|
• With arm at heart level; back supported and feet flat on the ground |
|
• On nondominant arm (or arm with the highest BP) |
BP monitor |
• Use a fully automated device with an upper arm cuff that has been validated by BHS, AAMI, or International Protocol for the Validation of Automated BP Measuring Devices |
|
• Monitors with memory that are able to store measurements are preferred |
Training of patients |
• Patients should be trained by their health care provider, and the monitor readings checked against mercury |
|
• Education content: hypertension and cardiovascular risk, BP measurement procedure, use of a validated monitor, cuff size, protocols for measuring BP, interpretation of BP readings, and monitor for their use only |
|
• Reevaluate patient technique and the accuracy of the device annually |
Target BP goal |
• 135/85 mm Hg, or 130/80 mm Hg if patient has diabetes, coronary heart disease, or chronic kidney disease (Class IIa; Level of Evidence B) |
Frequency and schedule of measurement |
Initial values (when patients begin HBPM): |
|
• Base decisions on a 7‐day measurement period with 2–3 measurements each morning and 2 to 3 measurements in the evening at prestipulated times (an average of 12 morning and evening measurements) |
|
• Exclude first‐day measurements from the analyses; take average of these values as the reference parameter in the subsequent dose‐titration phase |
|
Dose‐titration phase (titration of initial dose and adjustment of therapy): |
|
• All measurements should be made under identical conditions and at the same times of day as the initial values |
|
• HBPM data should be ascertained as trough values (ie, before medication is taken) in the morning and again at night |
|
• Use the average of BPs measured over 2 to 4 weeks to assess the effect of treatment |
|
Long‐term observation: |
|
• For stable normotensive (controlled) patients, patients should conduct HBPM a minimum of 1 week per quarter (an average of 12 morning and evening measurements under conditions described above) |
|
• Measurement should be made more frequently in patients with poor compliance |
