Why Does a Baby’s Blood Oxygen Level Drop?

Thursday, August 06, 2026

SAEDNEWS: Suffocation in infants can occur when the body does not receive enough oxygen. Red blood cells are responsible for carrying oxygen to the body’s tissues, and an insufficient amount of these cells may lead to changes in skin color.

Title: Understanding Low Blood Oxygen Levels: Causes, Symptoms, Prevention, and Treatment Options

Symptoms and Causes of Low Blood Oxygen Levels (Hypoxia)

Low oxygen levels in the blood may develop due to certain medications, asthma attacks, or over time because of heart problems and lung diseases such as chronic obstructive pulmonary disease (COPD) and emphysema. Although the symptoms of hypoxia can vary from person to person, some of the most common signs include the following:

Skin Discoloration

Red blood cells are responsible for carrying oxygen to body tissues. When oxygen levels are insufficient, the skin may change color. Cyanosis is a condition in which the skin develops a bluish or dark reddish appearance and occurs when oxygen levels drop significantly.

In people with darker skin tones, cyanosis may be easier to notice in the mucous membranes of the lips, gums, around the eyes, and under the fingernails.

Confusion

Confusion is a condition in which a person cannot think clearly or quickly, feels disconnected, and has difficulty maintaining attention, making decisions, or remembering things.

If you notice that you or someone else suddenly experiences these symptoms, it may indicate hypoxia. Sudden hypoxia can occur for several reasons, ranging from a severe asthma attack to problems affecting the heart or lungs.

Coughing

A severe asthma attack is one of the common causes of hypoxia. During an asthma attack, the lungs have difficulty receiving air because the airways become narrowed.

In an attempt to clear the lungs, a person may cough repeatedly. Although this is a natural response, it can also become dangerous because coughing requires additional oxygen and may worsen symptoms.

Rapid Heartbeat and Breathing

An increased heart rate usually occurs during physical activity. Therefore, experiencing a fast heartbeat while resting may be a sign of hypoxia.

When the body does not receive enough oxygen, the heart pumps blood faster to improve oxygen circulation throughout the body and meet the needs of cells.

Rapid breathing also occurs when the body attempts to increase oxygen intake. Normally, a person breathes about 12–16 times per minute, but during oxygen deficiency, the breathing rate may increase to 24 breaths per minute or more.

Shortness of Breath

Shortness of breath is considered one of the most noticeable symptoms of hypoxia. It often occurs as a result of increased heart rate and breathing rate.

Shortness of breath may occur even while resting and can become severe enough to create a feeling of suffocation. It may become more noticeable during physical activities and reduce a person’s ability to tolerate exercise.

Shortness of breath can also occur during sleep and may wake a person suddenly. In some cases, it may be accompanied by wheezing, especially during exhalation.

Oxygen is essential for the healthy function of all body systems. Cells require oxygen to work properly, and maintaining adequate oxygen levels is important for overall health.

Because cells cannot store enough oxygen for more than a few minutes, the body requires a continuous oxygen supply from the environment.

Causes of Low Blood Oxygen Levels in Infants and Adults

  • Blockage of the airway

  • Chronic obstructive pulmonary disease (COPD)

  • Emphysema

  • High altitude exposure

  • Interstitial lung disease

  • Pneumonia

  • Pressure-related heart and lung injuries caused by diving

  • Pulmonary edema

  • Pulmonary embolism

For people with chronic obstructive pulmonary disease, obtaining enough oxygen can be a constant challenge.
