Health Monitoring Devices

Devices for keeping an eye on the basics at home, including pulse oximeters, thermometers and blood pressure monitors.

A pulse oximeter clips onto a fingertip and reads oxygen saturation along with pulse rate. Cold hands, nail polish and movement all affect the result, so a surprising reading is worth repeating on a warm hand before you act on it.

None of these replace a conversation with your doctor or pharmacist. What they do is give you something specific to bring to that conversation, which is more useful than describing how you have been feeling.
