What is a Pulse Oximeter?

What is a Pulse Oximeter?

A pulse oximeter is a small, finger tip mounted or wrist mounted portable medical device that measures the oxygen saturation of a patient's blood as well a patient's heart rate. As opposed to measuring oxygen saturation through an invasive procedure such as a blood sample, a pulse oximeter is used as a painless and non-invasive medical instrument. Because of its ease of use and cost effectiveness, pulse oximeters are the preferred medical device in all clinical healthcare settings as well as for home diagnostics.

Pulse Oximeter for Adults

There are many different types that are suitable for adults. They range from basic models to more complex models. A great one that I particular like is the FamilyDoc 103-01 model.  It combines light weight and portability with multiple features including on-spot measurement of blood oxygen saturation, pulse rate, perfusion Index, and plethysmograph capabilities. It also has a bright color OLED Screen for easy reading.

Pulse Oximeter for Children

It is very important that a Pulse Oximeter for Children be specifically manufactured to fit their small fingers and rapid movements. The best one we found in all our tests was this FamilyDoc Model Finger Pulse Oximeter. It uses a customized oximetry sensor that can adjust for any size finger and skin to ensure accurate reading even for the smallest infants .
