Self-measurement of blood pressure
- MAM (Mean Arterial Measurement): MAM technology makes it possible to automatically
perform three repeated measurements in moments. Repetition is essential when measur-
ing blood pressure oneself, because isolated readings are often wrong for many reasons,
including the high variability of blood pressure, and high susceptibility to factors such as
recent exercise or stress… Taking 3 consecutive readings and averaging them can improve
the reliability of blood pressure measurement at home by a non-professional. This mode of
use is especially recommended by the American Heart Association (AHA).

- Rule of 3s: 3 readings recommended while sitting, resting, 3 days in a row: in the morning
before taking medications, 3 consecutive readings (MAM); in the evening after taking med-
ications, 3 readings in a row (MAM). A single reading is not necessarily significant, especially
in terms of monitoring your blood pressure.
- Self-measurement of blood pressure: The monitoring targets, for a known hypertensive
subject, using self-measurement at home, are different from those of the AHA, which es-
tablishes the classification of the blood pressure) and lower. These targets are based on age
and may vary depending on your condition.
General case: SBP* < 135 mmHg and DBP* < 85 mmHg
Age > 80 years: SBP* < 150 mmHg
Chronic renal failure: SBP* < 130 mmHg and DBP* < 80 mmHg
*
SBP: Systolic Blood Pressure - DBP: Diastolic Blood Pressure
The figures above are for general, informational purposes only and they must be re-validated in each case
with a physician.
It is important to check your targets, especially in cases of serious illness or preg-
nancy.

4. USE
4-1. INDICATIONS OF SELF-MEASUREMENT
Self-measurement of blood pressure is recommended for:
- Patients starting antihypertensive treatment to determine its effectiveness
- Patients requiring closer monitoring in between and prior to appointments (patients with
coronary heart disease, diabetes and / or renal disease)
- Pregnant women looking to prevent preeclampsia
- Patients at cardiovascular risk
- People displaying high blood pressure during an appointment, to eliminate a white coat
effect or confirm real hypertension
- Elderly patients whose blood pressure variability is increased, and whose frequency of
white coat effect gradually increases with age
- People suspected to mask hypertension (not detected at the doctor)
- In case of resistant hypertension
4-2. CONTRAINDICATIONS FOR SELF-MEASUREMENT
Self-measurement of blood pressure is contraindicated on:
- People under 18 years
- Patients suffering from:
Atrial fibrillation or other serious heart conditions;
Anxiety or obsessional disorders;
Elderly cognitive impairment (unless used by a third party);
Physical disability, Handicap
- An arm wearing a dialysis fistula, peripheral venous catheter: to avoid impair functioning of
the fistula or the catheter, the formation of blood clots in the vein,
- An arm having undergone axillary lymphadenectomy. The increase of the pressure in near-
by blood vessels can lead to the swelling of the arms and hands (lymphedema)
- A hemiplegic arm
