Automated Office BP

Automated Office BP

In recent years, Automated Blood Pressure Monitors have replaced the traditional mercury sphygmomanometer, and are just as reliable, without  posing a risk to the environment in terms of mercury pollution.

An additional concept is that these machines can be programmed  to deliver Automated Office Blood Pressure (AOBP).

The protocol for Automated Office Blood Pressure (AOBP) is as follows.

Omron

 

 

 

 

 

 

 

Programmed on an Omron ( or similar ) device

  • 3- minute rest  with doctor or nurse absent (conversation can elevate systolic  BP by 20mm)
  • 3 readings 1 min apart – averaged
  • Repeat if systolic readings vary by more than 20 mm

The results  demonstrate that AOBP is more reproducible and reliable than random single arm BP recordings.

AOBP overcomes issues of how problematic it  can be to attain an optimal  blood pressure reading whilst engaged in conversation , particularly where the conversation may entail potentially stressful emotional or medical issues.

Home Blood Pressure Monitors

Now that home and office use the same equipment in automated BP devices, then home BP monitor reading can be accepted by the treating doctor,  if clinic readings are erratic as in “white coat” hypertension.

The Home BP Protocol is to:

  • set up the BP monitor and place the pressure cuff on the arm;
  • have a three minute rest,  watching  TV,  or reading; then taking:
  • 3 readings one minute apart, averaged; and
  • repeating if systolic readings vary by more than 20 mm: these readings are recorded on a paper chart or (better still ) a computer file.

One week of home monitored readings is usually sufficient to establish a level, before or after a medication change.
Then,  weekly home BP readings can be used to supplement the doctor’s three-monthly readings.

Monitor Madness

Too often, the outcome of home BP monitoring can become an exercise in measuring stress levels. Most medical conditions such as headache, stress, fever, and pain of any cause produce normal elevations of blood pressure which is acceptable. In terms of  “urgent” assessment of acute illness or stress, simply  having a BP monitor does not give your home an accreditation as an emergency department.

When  in doubt go to the emergency department first, and think blood pressure second .
