A pulse oximeter is a lightweight device, small in size used for monitoring the amount of oxygen in the body. It is a non-invasive tool that attaches to your fingertip painlessly. It sends two wavelengths of light through your finger in order to measure the pulse rate and oxygen is in your system. After the oximeter completes its assessment, it will display the percentage of oxygen in your blood that comes from your heart along with your current pulse rate.
Your Blood Oxygen Saturation – SpO2 reading is an estimate of the amount of oxygen level in your blood. A SpO2 reading that is 95% or above is normally considered to be the normal oxygen level. But, a SpO2 reading that is 92% or less is an indication that your blood has a low level of O2 saturation that is insufficient and could cause a wide range of health conditions that are adverse. This could include an increased heart rate. chest pain and shortness of breath.
As we all know, our pulse rate is an estimate of the number of times our heart contracts in a minute. The normal pulse rate values for adults is said to be in the range of between 60 and 100 beats per minute. A lower heart rate while at rest implies an efficient heart function. In some people, a pulse rate that is below 60 bpm could indicate Bradycardia -an abnormally slow heart action. Bradycardia could cause a number of symptoms that are problematic that could include fatigue, chest pain, memory problems, and fainting.
A pulse oximeter is meant to provide you an accurate reading of your SpO2 and pulse rate in a matter of seconds. This could help you to respond confidently and quickly to tackle the abnormal readings. For this reason, many people who have adverse heart and lung conditions procure for themselves a personal oximeter for use at home.
It must be noted that the SpO2 and pulse rate measurements that are out of the normal range, are not always an indication of adverse health problems. Your heart rate during an exercise, for example, can be seen to increase and a slight decrease in oxygen saturation. (However, it must still remain at 90% or higher).
After the invention of Pulse Oximeters in the year 1995, the finger pulse oximeter became easily available for monitoring patients at home. Those having heart or lung problems can now use their own personal finger pulse oximeter under the guidance of a physician to manage their conditions.
For those suffering from COPD, asthma, or any other lung diseases and who would like to be active, the quality of the pulse oximeter they use is extremely important. Fast and reliable oximeter readings can play a significant role in helping patients to adjust their oxygen flow, especially while exercising, engaging in social activities. A monitoring device of good quality can also help doctors to monitor the efficacy of their treatment efforts and respond quickly in case the condition turns bad.
