Low and normal blood oxygen levels: What to know. Medically reviewed by Daniel Murrell, M. So, why is the spotlight on this health metric? Our bodies need oxygen to function. Oxygen enters the body through the nose and mouth and passes through the lungs into the bloodstream.
Once in the bloodstream, oxygen helps replace cells that wear out, provides energy for our bodies, supports the way our immune system functions and more. Low blood oxygen levels indicate that there may be an issue with your lungs or circulation. Pristas: People started to buy pulse oximeters to measure blood oxygen levels at home when they learned that low levels could be a sign of COVID Some thought this device could be a tool to help self-assess for signs and symptoms.
If your blood oxygen level is too low, you may need to boost your oxygen saturation. This is often done with supplemental oxygen. Home supplemental oxygen is considered a medication, and your doctor must prescribe it. Your health insurance may cover the expense. These conditions may prevent your lungs from adequately inhaling oxygen-containing air and exhaling carbon dioxide. Likewise, blood disorders and problems with your circulatory system may prevent your blood from picking up oxygen and transporting it throughout your body.
Any of these problems or disorders can lead to declining oxygen saturation levels. As your oxygen levels fall, you may begin experiencing symptoms of hypoxemia. People who smoke may have an inaccurately high pulse ox reading.
Smoking causes carbon monoxide to build up in your blood. If you smoke and need to know your blood oxygen level, an ABG may be the only way to receive an accurate reading.
Only people with health problems that cause low oxygen states are usually asked to check their levels. Even then, the less invasive pulse oximetry method is often as useful as an invasive ABG. Although it does have a margin of error, a pulse ox reading is usually accurate enough. If your doctor requires a more precise measurement, they can follow up with an ABG test.

Learn how to manage this…. Rapid, shallow breathing, also called tachypnea, occurs when you take more breaths than normal in a given minute.
Learn its causes, treatments, and…. Acute respiratory failure occurs when fluid builds up in the air sacs in your lungs. When that happens, your lungs can't release oxygen into your…. In this article we describe and demonstrate how a pulse oximeter like this one can be used to measure your oxygen level to adjust your oxygen study and to inform your doctor of a change in your condition. In addition, the oximeter can be used as a biofeedback training device along with pursed lips breathing to increase your oxygen level.
Your need for oxygen is continuous, the human body requires oxygen and food and water to create energy and oxygen has to be brought in from the outside air and carried to each and every cell. This is a continuous path of transport systems, your lungs deliver oxygen into your bloodstream, your heart pumps the blood to the tissues or oxygen is delivered to every cell.
Each cell has a manufacturing system called mitochondria, that uses oxygen and food to create energy for the muscles to power the body, carbon dioxide the waste product of this process is expelled. There is plenty of oxygen in the atmosphere to meet the needs of people with normal lungs.
However if you have lung disease, you may need extra oxygen to meet your body's oxygen requirements, you may have been diagnosed with COPD or lungs fibrosis. COPD is the combination of bronchitis, asthma and emphysema while lung fibrosis is the build up of scar tissue that impedes the transfer of oxygen.
Your doctor will prescribe oxygen based on the level of oxygen in your bloodstream during the rest, exertion and sleep. Oximetry is the most convenient method of testing your oxygen level. Your oximeter tells how much of your blood is filled with oxygen, your S. O2 oximetry reading is an important piece of information but it does not stand alone, combined with other information, you and your doctor can make important decisions to guide your self-management program.
The diaphragm pulls down and the chest muscles pull out to lengthen and widen the chest to make room for air to enter the lungs. Oxygen in the air reaches the expanding alveoli or air sacs where network of tiny blood vessels called capillaries receives the oxygen as it diffuses across the alveolar capillary membrane, at the same time carbon dioxide which is produced in the body's cells and carried on the haemoglobin molecule, the red blood cell detaches and defuses across the alveoli capillary membrane to be exhaled through the atmosphere.
Once in the blood oxygen quickly attaches to the haemoglobin molecule of the red blood cell, turning it red. Freshly oxygenated blood is pumped by the heart through the major arteries towards the vital organs muscles and other, reaches delivering oxygen to each and every cell once inside the cell, oxygen finds its way to the mitochondria which uses the oxygen to create energy.
Carbon dioxide the end product of the body's metabolism is carried by the blood stream to the lungs where it is exhaled to the atmosphere, thus completing one of millions of cycles that sustain life.
As your red blood cell gathers oxygen onto the haemoglobin molecule, it turns red. The oximeter functions by shining two lights, red and infrared through your finger, sensors on the other side of your finger detect how much of each light is passing through.
The red light measures un-oxygenated haemoglobin whereas the infrared light measures oxygenated haemoglobin. A tiny computer inside the oximeter compares the two lights and displays a number on the screen that tells what percentage of haemoglobin is saturated with oxygen. The oximeter is designed to take its reading at the peak of the pulse where the blood contains the most oxygen and any other point on the pulse there is less oxygenated blood causing in inaccurate reading.
Arterial blood gases measure your oxygen saturation level by drawing blood from your artery. Oximetry measures only oxygen but it does so non-invasive and continuously. It is not invasive, inexpensive useful during exercise and sleep, patients can use it at home or anywhere and patients can use it to learn how to increase their oxygen level.
Position the accelerator clip on your finger keeping your finger steady, wait for a strong steady pulse and consistent SPO2 then take your reading. Avoid Dark nail polish or artificial nails, don't tighten your head as it may cut off the circulation to your finger.
