A pulse oximeter (pulse ox) is a small, portable device that is used to non-invasively measure the oxygen saturation levels in the blood.
A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram. Pulse oximeters are medical devices commonly used throughout the healthcare industry. A pulse oximeter (pulse ox) is a small, portable device that is used to non-invasively measure the oxygen saturation levels in the blood. The pulse oximeter will show the % oxygen saturation and the pulse rate of the user. oximetry. measurement of oxygen saturation of the blood using an oximeter. pulse oximetry a noninvasive method of indicating the arterial oxygen saturation of functional hemoglobin, using a pulse oximeter. Pulse oximetry is a non-invasive method for monitoring a person's O 2 saturation. In its most common (transmissive) application mode, a sensor device is placed on a thin part of the patient's body, usually a fingertip or earlobe, or in the case of an infant, across a foot. pulse ox·i·me·ter. A spectrophotometric device that noninvasively estimates saturation of arterial oxyhemoglobin (SaO 2) by use of selected wavelengths of light. an instrument attached to a finger or ear for non-invasive measurement of the percentage saturation with oxygen of haemoglobin (Hb) in the blood. Definition of Pulse Oximeter: A pulse oximeter is a device intended for the non-invasive measurement of arterial blood oxygen saturation and pulse rate. The oxygen level from a pulse oximeter is reasonably accurate. Most oximeters give a reading 2% over or 2% under what your saturation would be if obtained by an arterial blood gas. For example, if your oxygen saturation reads 92% on the pulse oximeter, it may be actually anywhere from 90 to 94%. Pulse oximetry is a procedure used to measure the oxygen level (or oxygen saturation) in the blood. It is considered to be a noninvasive, painless, general indicator of oxygen delivery to the peripheral tissues (such as the finger, earlobe, or nose).
