Learn about the Oksigen Saddle Index (ODI) in a dream


Oxygen extension index (ODI) is an insufficient blood oxygen measurement during sleep. If you have a dream diagnostic survey, it may be one of the components in the report that you describe its results.

Oxiological saturation is a measure of oxygen in your blood.Oxygen oxygen (low oxygen saturation) means that the percentage of oxygen in your blood is less than it should be.

Low oxygen saturation is one of the indicators that can attend the risk of long-term health consequences, such as sincere disease (heart), as well as dementia .

Find out how the oxygen solution is measured and how the results can be useful for determining sleep apnea and other conditions that can be associated with drops at the oxygen level during sleep.

What is ODI?

ODI is the number of times per sleep hour so that your oxygen level in your blood falls at a certain degree from the baseline. Falls at the level of oxygen in the blood are called dealerships.

Details can occur due to diseases (for example, pulmonary disease) when it does not sleep, but they are even more likely when you sleep. Apnea Sleep is the most common cause of cinema oxygen during sleep.

ODI is generally measured as part of standard sleep studies, such as:

saturation of blood artery and denaturation -This is a measure of an oxygen percentage in the arteries that are blood vessels that contain the highest percentage of oxygenated blood in the body. Arterial oxygen products can be measured during awakening and sleeping with non-invasive tests.

Some other aspects of your breathing can affect your oxygen saturation and ODI results,And each one of them is reported separately as part of a comprehensive surgery:

  • Risk rotation quickly breathe
  • APENAPISODES Suspended breathing for at least 10 seconds
  • Hipopnexate or respiratory smallPisodios,The duration of the 4 seconds without less than 4% of nudging oxygen and at least 30% reduction in the air flow
  • The absolute minimum blood oxygen level,that can be called a minimum oxygen saturation or oxygen studies nadir / Li>

odi is measured in a pulse oximeter , this device is usually placed in the PALP,What shines red light on the skin and can estimate the amount of oxygen in peripheral blood.

Government recommendations

Normal oxygen saturation should be 96 to 97%.The fall below 90% is considered abnormal soft, from 80 to 89% is considered moderately abnormal, and below 80% is considered strongly abnormal.

Your ODI scored on the basis of how much and how often your oxygen level is reduced during the test. The degree of changes of The baseline can be measured in two different ways.

The criteria used to determine the index may vary according to the governed points used:

  • according to the Administration of the American Sleep Sleep Academy,Any respiratory material during sleep with a fall of 3% of the oxygen level in the blood is considered as a whole. For example, a change from 95% to 92% would be an event that is calculated in the total number of index.
  • , however, Medicare and some other insurance still depend on the oldest points of the points and require a reference to 4% for the event to be calculated in the index.

One, which indicates frequent or severe detection, correlates with a significantly reduced oxygen level, but does not identify this cause problemsU health care provider will determine the cause of your documentation,Given your history of medical, physical and, possibly, other diagnostic tests.

As a general rule, the longer and deeper trocytes are associated with the worst obstructive apnea (OSA), and the evaluation criteria are designed to reflect these components.

Your result may be accurate if the stages of sleep are not recorded during your test.If the sleep stages are not evaluated, your ODI index may be averaged throughout the recording time, instead of just your sleep, time timing, your test time may include the time spent later.This can cause an incorrect result, which overestimates or underestimates its oxygen saturation and ODI during sleep.

What causes the protected IDI?

During sleep, the muscle tone is slightly reduced.It does not have a remarkable or substantial effect for most people.

but normal reduction of muscle tone during sleep means that ODI can get worse with diseases that affect breathing or oxygen in the blood.

Apnea and hypopoty

When breathing becomes interrupted during sleep, the toxiegos of blood can fall.With OSA and other conditions that affect OIDI, these drops are usually associated with apnea orhyppedea.

  • obstructive apnene is a complete interruption of breathing.This is the symptom of the most common OSA, and this is due to blocking the upper respiratory tract, generally due to the greater trend of the throat muscles to rest during sleep.
  • Central Apnea Sleep is much less common than Osa. It is a pause in breathing during sleep caused by disturbed respiratory control of the brain or heart failure or heart malfunction.
  • Hypopne is an episode of respiratory disorders, which is a partial collapse of the respiratory tract.
  • Oxygen drops can occur due to snoring or upper respiratory resistance syndrome (UARS), two conditions in the who breathes worried, but to a lesser extent that Osa.

odi differs from apnea-hypopnea (there) index , which is another dimension. There it also includes events that can cause wars or wake up from sleep without affecting oxygen levels.

Sleep fragment, which is a sleep interruption, can occur due to these respiratory problems. Sleep interruptions can happen or without associated renewers.Even when the fragmentation of sleep is produced without affecting oxygen saturation, it can cause drowsiness during the day due to the inadequate amount of sleep reduction.

Other reasons

Other conditions can cause breathing and / or oxygenation problems while they sleep and influence your ODI.

For example:

  • obesity hypustration syndrome sleep. , Diseases do not respond.
  • Heart disease , such as stagnant heart failure or mitral valve disease or pulmonary disease, including disease Chronic obstructive pulmonary (COPD) live often with the wasp,But they can call Odi even without an existing joint bone.

Several of these conditions contribute to each other, and OSA often coexists with other medical problems that affect breathing, as copd .

Advanced If you have an OSA and another important health problem that affects your oxygen level, the effects on the oxygen level during sleep can be significantly worse.With a decrease in lung reserves or reduced heart function, upper respiratory tract collapse can lead to an increase in oxygen levels of your blood, and more than if you only had OSA.

Health effects

The recircional episodes of oxygen children can lead to a hyposensimia (reduced blood oxygen) and hypoxia (reduced oxygen in body tissues ).

Hypoxia and hypoxi can be harmful to your body, especially if the problem is longer and repeated.

If oxygen levels are low enough (often, less than 88% is a threshold) and is admitted for more than five minutes, it can cause hypoxia or hypoxia.

> ODI can also be associated with:

  • Extended level of extended carbon dioxide,What can be detrimental to your health
  • Oxidative tension and free radical body formation
  • Resistance insulin and greater diabetes risk
  • Somnolence day andDifficulties concentration
  • Modified metabolism and obesity

Factors can predict cardiovascular.Vascular risks, including hypertension (high blood pressure), cancer, heart attack, stroke, arrhythmias, as a blinking atria, as well as a memory loss associated with dementia.These consequences are an active area of sleep research.


The treatment of odi anomalies during sleep depends on the cause.As a general rule, the OSA, the most common cause of ODI’s problems is processed using a constant positive respiratory tract pressure (CPAP) ,It can normalize breathing and reduce the long-term risks associated with unprocessed sleep apnea. / P>

Sometimes Other sleep apnea procedures, including operation, are considered treatment for OSA, which makes it not improve with more conservative measures.

Treatment for other causes of ODI problems may include the management of basic factors that contribute and may include weight loss.Sometimes, the treatment of lung diseases or heart disease can help improve the ODI.

And for some people who have a bear or other causes of ODI tasks, additional oxygen additives can be useful.

Frequently Asked Questions (FAQ)

What is the normal level of the oxygen index?

Although the normal level of the oxygen denaturation index was not installed universally,The most common level to be considered normal, less than five episodes of denaturation per sleep hour.

In what finger can it be used for a pulse oximeter to measure the ODI level?

The pulse oximeter clip can be used with any finger, but a study suggests that for those prescribing hand,The right middle finger and the right thumb provide the most accurate measure of the ODI level. also, in the study, for a limited number of participants who were dominant, the finger Half left and the left finger gave the most accurate reading of ODI.

What is a dangerous low oxygen level?

Any level of blood oxygen less than 95% requires a medical edge, and immediate medical attention is needed for the level of oxygen below 85%.

Word of the Meds information received

If you think fatigue during the day or have difficulty, despite the normal amount of sleep, you can try the sleep and / or abnormal ODI.Talk to your health care provider about whether the study will be to find out what happens and defines the best procedures for your condition. Respiratory resolution on a sleeping riot can benefit both the quality of sleep and long-term health.
