iHealth Clear (BPM1) - Precautions for use

An individual's blood pressure is not constant, it varies during the day depending on different factors:

• It decreases at rest and increases with physical activity,
• It falls when asleep,
• It increases with meals,
• It varies with the ambient temperature,
• A strong emotion causes a significant increase (systolic pressure can reach 200 mmHg in a perfectly normal subject)

Knowing this, there are some precautions for use to observe before and during measurement:

• Take your measurements under the same conditions (at the same time of day, on the same arm),
• Relax for 5 minutes before taking a measurement,
• Sit comfortably in a quiet place, feet flat on the floor, without crossing your legs,
• Place the cuff at the same level as your heart. See how to place the cuff properly,
• Don't talk and don't move for the entire measurement,
• Breathe normally.
