What is a Home Blood Pressure Cuff?

A home blood pressure cuff is a device used to measure the pressure of blood flowing through your arteries. It usually consists of an inflatable cuff that wraps around your upper arm and a monitor that shows your blood pressure readings. These devices are designed for easy use at home and help track your blood pressure over time.

Preparing to Measure Your Blood Pressure

Before taking a reading, sit quietly for 5 minutes. Avoid caffeine, exercise, and smoking for at least 30 minutes beforehand. Use the restroom if needed. Sit with your back supported, feet flat on the floor, and arm resting at heart level. Remove tight clothing from your arm. These steps help ensure accurate measurements.

How to Use the Blood Pressure Cuff

1. Wrap the cuff snugly around your upper arm, about 2–3 cm above the elbow.

2. Make sure the cuff’s tubing is aligned with the artery on the inside of your arm.

3. Turn on the device and stay still and quiet while it inflates and measures.

4. Record the systolic (top number) and diastolic (bottom number) readings.

5. Take 2–3 readings one minute apart and average them for accuracy.

When to Seek Medical Help

If your readings are consistently very high (e.g., systolic over 180 mm Hg or diastolic over 120 mm Hg) or very low (e.g., systolic below 90 mm Hg), or if you experience symptoms like chest pain, severe headache, shortness of breath, dizziness, or weakness, seek emergency medical care immediately. These could be signs of serious health problems.

How to prepare for your tele-visit

• Sit quietly for 5 minutes before measuring.
• Avoid caffeine, smoking, and exercise for 30 minutes prior.
• Ensure you have a properly fitting cuff for your arm size.
• Sit with back supported and feet flat on the floor.
• Have a notebook or device ready to record readings.

After your tele-visit

• Review and record your blood pressure readings carefully.
• Share your readings with your healthcare provider as advised.
• Follow any recommendations given by your provider based on readings.
• Maintain regular monitoring schedule as recommended.
• Seek immediate care if you notice red flag symptoms or dangerous readings.
