Oxygen Saturation Monitor For Home Use
A noninvasive procedure of measuring the oxygen present in the bloodstream can be carried out with the use of an oxygen saturation monitor. You can perform this test at home or seek help from professional care personnel. In the medical field, oxygen saturation level is often referred to simply as O2 SAT.
Oxygen levels can vary from person to person and will fluctuate even within each individual. These fluctuations can be attributed to a person’s level of physical fitness, physical activity, conditions which affect the respiratory system and one’s general overall health at any given time.
Normal O2 saturation: As per the ninth edition of diagnostic and laboratory test reference of Mosby, the normal oxygen saturation level in a person’s bloodstream is equivalent to 95% or greater
Uses: There are many reasons for performing the oxygen saturation monitor test. This includes assessing the response of the person to medications as well as ensuring that the current oxygen level of the person is adequate for normal respiratory function. This test can also be performed for sleep studies and stress testing. People who suffer from sleep apnea or those who use PAP therapy may benefit from the use of an oxygen saturation monitor.
The Test: The test itself is simple and painless. It includes placing a pulse oximeter probe on the fingertip or the ear of the person. It normally takes only a few seconds to know the oxygen saturation level in the blood. It is an easy and accurate way of measuring the oxygen saturation levels.
A pulse oximeter generally is a tiny clip which is attached to the finger of the patient. Two bright lights shine in the oximeter, one infrared and the other red, which measures the oxygen saturation level in the blood. This is done by analyzing the arterial blood color. Blood which is rich in oxygen is bright red. In order to separate the arterial blood from the tissue which surrounds it, the oximeter will measure the overall color change in harmony with the pulse beating.
To ensure accuracy an oxygen saturation monitor needs a strong regular pulse rate for registration. People having cold feet and hands may at times possess weak pulses due to poor circulation and can result in inaccurate readings.
Considerations: People with some lung conditions such as COPD (chronic obstructive pulmonary disease) might exhibit an oxygen saturation level which is lower, therefore becoming their “normal”. As per the Thoracic Society of America, the main goal of oxygen saturation is for maintaining more than 90% of oxygen saturation level.
Warning: Oxygen is the most essential part of our lives. In order to function properly humans need to have an adequate amount of oxygen throughout the body. The oxygen saturation monitor gives a clear indication of the quantity of oxygen available in the blood. As per the ninth edition of laboratory and diagnostic test reference of Mosby, oxygen saturation level which is equal to or below 75% may be critical. An O2 SAT level that is very low may be an indication of catastrophic illness. Therefore, in the hospital oxygen saturation is monitored as well as the blood pressure and pulse rate to determine the condition of the patient.
Facts: Oxygen is transported throughout the body with the help of blood which is called hemoglobin; it is a red blood cell that has iron-containing protein. Hemoglobin molecules are able to hold a maximum of four oxygen molecules. The oxygen saturation level is determined by the oxygen percentage passed in the blood.
Significance: If the oxygen saturation level of the person is very low that means there is an inadequate supply of oxygen necessary for their body cells and vital organs. An oxygen saturation monitor for home use can be very helpful for people with chronic diseases such as COPD and asthma, those suffering with sleep apnea and other conditions, as well as athletic individuals who want to keep an eye on their O2 SAT levels such as mountain climbers who ascend to higher altitudes.
