Home Blood Pressure Monitors and Pulse Oximeters
Medical-style devices at home can be genuinely useful, especially when a doctor has asked you to keep a record. They work best when used the way the instructions describe.
Blood pressure monitors
A sphygmomanometer, or blood pressure monitor, uses an inflatable cuff. At home, cuff size and position matter a great deal.
- Use a cuff of the right size for your arm; the manual explains how to check.
- Sit quietly for a few minutes first, back supported, feet flat.
- Keep the arm supported at heart level and do not talk during the reading.
- Take readings at the times your doctor suggests, and record them all.
Pulse oximeters
Pulse oximetry is a non-invasive way to monitor blood oxygen saturation, usually with a clip on a fingertip. Cold hands, movement and nail polish can affect readings.
Choosing a device
Look for devices that state they meet medical device requirements in your country, and ask a pharmacist or doctor if unsure.
Home readings support conversations with a clinician; they do not replace them. If you feel unwell, seek medical help whatever the device shows.
