What is The Normal Oxygen Level?

/0 Comments/in , /by

Blood oxygen level is the amount of oxygen circulating in the blood. Your blood oxygen level measures how much oxygen is circulating with your red blood cells. The body closely monitors blood oxygen levels to keep them within a specific range, so that there is enough oxygen for the needs of every cell in the body. A person’s blood oxygen level is an indicator of how well the body distributes oxygen from the lungs to the cells, and it can be important for people’s health.

What should oxygen levels be?

Normal arterial oxygen pressure (PaO2) measured using the arterial blood gas (ABG) test is approximately 75 to 100 millimeters of mercury (75-100 mmHg). A blood oxygen level below 60 mm Hg is considered low and may require oxygen supplementation, depending on a doctor’s decision and the individual case.

Hypoxemia is diagnosed by physical examination and generally detected using ABG testing and is defined as blood oxygen levels above 120 mmHg.

When the level goes below 75 mmHg, the condition is generally termed hypoxemia. Levels under 60 mmHg are considered very low and indicate the need for supplemental oxygen. Supplemental oxygen is provided through an oxygen cylinder that is connected to the nose via a tube, with or without a mask.

Your blood oxygen level is measured as a percentage—95 to 100 percent is considered normal.

You should be check your blood oxygen if

  • Chronic obstructive pulmonary disease (COPD)
  • Pulmonary fibrosis
  • Pulmonary hypertension
  • Cystic fibrosis
  • Asthma
  • Congestive heart failure

Other conditions include:

  • Anemia
  • Sleep apnea (temporary cessation of breathing during sleep)
  • Smoking

How is the blood oxygen level measured?

The most efficient way to monitor blood oxygen levels is by an arterial blood gas or ABG test. For this test, a blood sample is taken from an artery, usually in the wrist. This procedure is very accurate, but it can be a little painful. Another fast and easy way is by the use of a pulse oximeter. It’s a small device that clips onto your fingertip. It shines a light into the tiny blood vessels in your finger and measures the oxygen from the light that’s reflected back.

When to see a doctor

  • severe and sudden shortness of breath
  • severe shortness of breath that get worse during exercise or physical activity
  • shortness of breath even when at rest
  • wake suddenly with shortness of breath or a feeling of choking

What is Oxygen Saturation Monitoring in Children?

/0 Comments/in , /by

As parents, making sure that your child is healthy and happy is always a topmost priority. We are always in the lookout for any signs that can compromise their health. We want to monitor as much as we can on everything that happens to them.

One of the signs that we should be on guard for is Cyanosis or Turning Blue. This happens when there is not sufficient level of oxygen in the blood. It can be evident at birth but can also appear any time later in life and most often accompanies conditions in which the lungs or heart is compromised.

Cyanosis is one of the symptoms of Hypoxemia, a medical condition wherein there is an abnormally low level of oxygen in the blood. More specifically, it is oxygen deficiency in the arterial blood.

Oxygen saturation means the amount of oxygen being carried in your child’s red blood cells. The optimal oxygen saturation of the blood lies between 95-98 %. Anything less than 95% results in hypoxemia and should be a major concern.

How is oxygen saturation monitoring in children done? One way to measure oxygen saturation is through a test called arterial blood gas. Instead of taking the blood from the vein, it is taken from the artery and the amount of oxygen present is determined.

Another way is through a pulse oximeter. A pulse oximeter like CMS-50QB ‏is one device that can be used to monitor oxygen saturation. It is a simple, portable monitor for measuring oxygen saturation and pulse rate and is suitable for use indoors and outdoors. It is also used in monitoring COPD patients or those who suffer chronic obstructive pulmonary disease.

On one side, the clip contains a strong light source, which shines through the finger. On the other side, a sensor measures what proportion of the light penetrated through the finger and what was absorbed. Different proportions of light penetrate the finger according to the level of saturation of the blood. From this, the oxygen saturation figure is calculated. The pulse rate can also be measured and displayed. The sensor or probe is connected to the monitor by a long thin, wire. It can be used on the finger or the toe.

The monitor and sensor or probe is totally safe, non-invasive and will not hurt your child when it is applied securely but not tightly on the finger or toe. The probe or sensor may be used on a different toe or finger every 8 hours to make sure that the device is working and to give the child’s finger or toe some rest.

Children with low level of oxygen saturation need to be connected to the monitor at all times so that their level of oxygen is constantly monitored. While for others, monitoring can be done when they are sleeping. Your doctor or health provider will determine how long your child needs to be monitored.

When your child’s oxygen is low, oxygen therapy is done so that your child will receive a higher concentration of oxygen than we normally breathe in the air. A face mask or nasal tube is connected to a mechanical ventilator.
