What is a
pulse oximeter?
A pulse oximeter is a device that measures the oxygen saturation
level in a patient’s blood. The oxygen saturation level represents
the amount of oxygen carried in the blood.
How does it work?
The pulse oximeter has a probe that must be in contact with a
patient’s skin to work, usually the finger, nose or earlobe. The
probe gives off light that is able to tell the oxygen saturation
level in the blood.
Does the pulse oximeter hurt?
No, the probe is lightly contacting the skin. It does not cause any
discomfort.
Are there any complications associated with
the use of a pulse oximeter?
There are no complications associated with the use of a pulse
oximeter. The pulse oximeter may not be accurate in certain
conditions such as very low blood pressure or very poor heart
function.
