- Hypoxemia is a below-normal level of oxygen in your blood, specifically in the arteries. Hypoxemia is a sign of a problem related to breathing or circulation, and may result in various symptoms, such as shortness of breath. Hypoxemia is determined by measuring the oxygen level in a blood sample taken from an artery (arterial blood gas). It can also be estimated by measuring the oxygen saturation of your blood using a pulse oximeter — a small device that clips to your finger.

- Hypoxemia (low oxygen in your blood) can cause hypoxia (low oxygen in your tissues) when your blood doesn't carry enough oxygen to your tissues to meet your body's needs. The word hypoxia is sometimes used to describe both problems.auses of Hypoxia. A severe asthma attack, or flare, can cause hypoxia in adults and kids. During an attack, your airways narrow, making it hard to get air into your lungs. Coughing to clear your lungs uses even more oxygen and can make symptoms worse.

Hypoxemia Causes. Hypoxemia refers to insufficient oxygen in the blood. Thus any cause that influences the rate or volume of air entering the lungs (ventilation) or any cause that influences the transfer of air from the lungs to the blood may cause hypoxemia

Hypoxemia Hypoxemia occurs when there is a low level of oxygen in your blood. Oxygen is needed to keep your organs and tissues alive. Long-term hypoxemia can become life threatening if it is not treated.

- Hypoxemia, or low blood oxygen, describes a lower than normal level of oxygen in your blood. In order to function properly, your body needs a certain level of oxygen circulating in the blood to cells and tissues.hough the pulse oximeter actually measures the saturation of oxygen in your blood, the results are often used as an estimate of blood oxygen levels. Normal pulse oximeter readings range from 95 to 100 percent, under most circumstances. Values under 90 percent are considered low.

Hypoxia and Hypoxemia Some of the many causes of hypoxia are the following: 1  Chemical or gas poisoning (for example cyanide, carbon monoxide) 2  Low or absent concentration of oxygen (for example, high altitudes reached without supplemental oxygen as seen in mountain climbing, and aviation, drowning or fires)  Lung problems, for example:

Causes of Low Blood Oxygen Levels Oxygen derived from the air is delivered via the bloodstream to the body organs and tissues. A low blood oxygen level, or hypoxemia, can occur due to reduced environmental oxygen or a problem affecting the respiratory or circulatory system. In many people with hypoxemia, several factors contribute to the low blood oxygen level. Video of the Day

- How Low Oxygen Levels Affect the Body. Low oxygen levels affect a number of systems in the body. A lowered mix of oxygen in the blood causes the vessels of the lungs to narrow. This causes the heart to pump harder. It strains to get blood through the lungs.

Tools for Emergency Oxygen The air a person normally breathes contains approximately 21 percent oxygen. The concentration of oxygen delivered to a victim through rescue breathing is 16 percent. A condition known as hypoxia (insufficient oxygen to the body) can occur if a person goes without adequate oxygen for an extended period. Signs and symptoms of hypoxia include: Increased breathing and heart rate.

- In the lungs, the oxygen crosses a membrane, traveling from the many tiny air sacs in your lungs into your blood. A low amount of oxygen in the blood can be due to any lung condition that interferes with you receiving a good, deep breath and getting enough oxygen traveling from the air sacs into the blood.

Hypoxemia Hypoxemia (or hypoxaemia in British English) is an abnormally low level of oxygen in the blood. More specifically, it is oxygen deficiency in arterial blood. Hypoxemia has many causes, often respiratory disorders, and can cause tissue hypoxia as the blood is not supplying enough oxygen to the body.

Hypoxemia If the alveolar ventilation is insufficient, there will not be enough oxygen delivered to the alveoli for the body's use. This can cause hypoxemia even if the lungs are normal, as the cause is in the brainstem's control of ventilation or in the body's inability to breathe effectively.

- Quick Answer. Causes of low blood oxygen levels include blocked airways, high altitudes, anemia, pneumonia, interstitial lung disease, acute respiratory distress syndrome and sleep apnea, according to Mayo Clinic.
