What is Pulse Oximetry?
For people with COPD, asthma, Congestive Heart Failure (CHF) and other conditions, pulse oximetry is a technology used to measure the oxygen level in your blood and your heart rate. A finger pulse oximeter is equipped with technology to rapidly detect changes in your blood oxygen level. It can help give you the knowledge you need to take control of your condition. A finger pulse oximeter is easy to use – just clip it on your fingertip to get a blood oxygen reading.
How Does a Pulse Oximeter Work?
A finger pulse oximeter functions by shining light through your finger. The sensors detect how much oxygen is in your blood based on the way the light passes through your finger. Pulse oximetry is the technology calculating the results to display a number on the oximeter’s screen that tells you the percent of oxygen in your blood. A finger pulse oximeter also measures your pulse rate.
Everyone’s oxygen saturation fluctuates, especially when changing activities throughout the day. To determine your normal oxygen range, simply check your oxygen saturation 4 times a day for 5 days using your personal Nonin GO2 brand fingertip oximeter. Record each measurement in the activity log and be sure to also record what you were doing prior to checking.
Oxygen saturation measures how much oxygen the blood is carrying compared with its full capacity.
· An SpO2 of greater than 95% is generally considered to be normal.
· An SpO2 of 92% or less (at sea level) suggests hypoxemia.
In a patient with acute respiratory illness (e.g., influenza) or breathing difficulty (e.g, an asthma attack), an SpO2 of 92% or less may indicate a need for oxygen supplementation.
In a patient with stable chronic disease (e.g., COPD), an SpO2 of 92% or less should prompt referral for further investigation of the need for long-term oxygen therapy .5,6
Pulse oximetry can be a useful aid in decision-making, but is not a substitute for a clinical assessment nor sufficient for diagnosis by itself. Arterial blood gas measurements, obtained by arterial puncture, remain the gold standard for measurement of oxygen saturation.
