Why do baby oxygen levels drop when sleeping?

When babies sleep, their breathing patterns can change, leading to a drop in oxygen levels. This is because during sleep, the body’s respiratory system tends to relax and slow down. As a result, the exchange of oxygen and carbon dioxide in the lungs may become less efficient. Additionally, babies have smaller airways compared to adults, which can further contribute to decreased airflow and lower oxygen levels.

During deep sleep, babies may also experience periodic breathing, where they have short pauses in their breathing followed by rapid breathing. These pauses in breathing can temporarily decrease oxygen levels in the blood. However, this is usually considered normal in healthy infants and does not cause any harm.

Factors contributing to drops in baby oxygen levels during sleep:

  • The relaxation of the respiratory system
  • Smaller airways
  • Periodic breathing during deep sleep

At what age do baby oxygen levels start dropping during sleep?

Baby oxygen levels can start dropping during sleep from birth onwards. Newborns are particularly susceptible to experiencing drops in oxygen levels due to their immature respiratory systems. As babies grow and develop, their respiratory systems mature and become more efficient at maintaining stable oxygen levels during sleep.


The risk of drops in oxygen levels is highest during the first few months of life but gradually decreases as the baby gets older. By around six months of age, most babies have developed enough control over their breathing that drops in oxygen levels become less frequent.

Risk factors for drops in baby oxygen levels:

  • Newborn age
  • Immature respiratory system

What are the potential risks associated with low baby oxygen levels during sleep?

Low baby oxygen levels during sleep can potentially lead to various health risks. Oxygen is crucial for the body’s organs and tissues to function properly, especially the brain. Prolonged or significant drops in oxygen levels can result in hypoxemia, which is a condition characterized by low blood oxygen.

If left untreated, hypoxemia can cause complications such as:

1. Developmental delays:

Insufficient oxygen supply to the brain can affect its development and lead to delays in cognitive and motor skills.

2. Sudden Infant Death Syndrome (SIDS):

In rare cases, severe drops in oxygen levels during sleep can contribute to SIDS, a sudden and unexplained death of an otherwise healthy infant.

Potential risks associated with low baby oxygen levels:

  • Developmental delays
  • Sudden Infant Death Syndrome (SIDS)

How can parents monitor their baby’s oxygen levels while they sleep?

To monitor their baby’s oxygen levels while they sleep, parents have several options available:

1. Pulse oximeters:

Pulse oximeters are small devices that clip onto a baby’s finger or toe to measure their blood oxygen saturation level. These devices use infrared light to detect the amount of oxygen in the blood.

2. Breathing monitors:

Breathing monitors are designed to detect changes in a baby’s breathing patterns during sleep. These monitors typically use sensors placed on the baby’s chest or abdomen to track respiratory movements.

Methods for monitoring baby’s oxygen levels during sleep:

  • Pulse oximeters
  • Breathing monitors

Are there any warning signs that indicate a drop in baby oxygen levels during sleep?

While drops in baby oxygen levels during sleep may not always be accompanied by noticeable symptoms, there are some warning signs that parents can watch out for:

1. Changes in skin color:

If a baby’s skin appears bluish or pale during sleep, it could indicate low oxygen levels.

2. Rapid breathing or panting:

A baby who is struggling to maintain adequate oxygen levels may exhibit rapid or shallow breathing patterns.

Warning signs of drop in baby oxygen levels:

  • Changes in skin color (bluish or pale)
  • Rapid breathing or panting

Can certain sleeping positions or environments contribute to a drop in baby oxygen levels?

The sleeping position and environment can play a role in the occurrence of drops in baby oxygen levels. Certain factors can contribute to restricted airflow, potentially leading to decreased oxygen saturation. For example:

1. Sleeping on the stomach:

Sleeping on the stomach can increase the risk of obstructed breathing and lower oxygen levels, particularly for infants who are unable to turn their heads or lift them up when facedown.

2. Overheating:

An excessively warm sleep environment can cause a baby to breathe rapidly and lead to increased sweating, which may result in lowered oxygen saturation.

Factors contributing to drops in baby oxygen levels during sleep:

  • Sleeping on the stomach
  • Overheating

Are there any medical conditions or factors that make babies more prone to experiencing drops in oxygen levels during sleep?

There are certain medical conditions and factors that can increase a baby’s susceptibility to drops in oxygen levels during sleep. These include:

1. Premature birth:

Babies born prematurely often have underdeveloped lungs and respiratory systems, making them more prone to experiencing drops in oxygen levels.

2. Respiratory infections:

Infections such as bronchiolitis or pneumonia can cause inflammation and congestion in the airways, leading to compromised breathing and decreased oxygen saturation.

Factors increasing baby’s risk of drop in oxygen levels during sleep:

  • Premature birth
  • Respiratory infections

What measures can parents take to ensure optimal oxygen levels for their babies while they sleep?

To help maintain optimal oxygen levels for their babies while they sleep, parents can consider the following measures:

1. Safe sleeping practices:

Place babies on their backs to sleep, as this position is associated with a lower risk of SIDS and allows for better airflow.

2. Maintain a comfortable sleep environment:

Avoid overheating the room or using heavy blankets that could impede airflow. Dress babies in appropriate clothing for the ambient temperature.

Tips for ensuring optimal baby oxygen levels during sleep:

  • Safe sleeping practices (back sleeping)
  • Maintain a comfortable sleep environment (avoid overheating)

Are there any technologies or devices available to help maintain healthy oxygen levels in babies during sleep?

There are various technologies and devices available that can assist in maintaining healthy oxygen levels in babies during sleep:

1. Oxygen supplementation:

In cases where a baby has a medical condition that affects their ability to maintain sufficient oxygen levels, supplemental oxygen therapy may be prescribed by a healthcare professional.

2. Breathing monitors with alarms:

Some breathing monitors are equipped with alarms that alert parents if their baby’s breathing becomes irregular or if there is a significant drop in oxygen levels.

Technologies and devices for maintaining healthy baby oxygen levels during sleep:

  • Oxygen supplementation
  • Breathing monitors with alarms

Do all babies experience drops in oxygen levels during sleep, or is it only a concern for certain individuals?

Drops in baby oxygen levels during sleep are common and generally not a cause for concern. Most healthy infants experience occasional dips in oxygen saturation without any adverse effects. However, there are certain individuals who may be at higher risk of experiencing significant drops in oxygen levels, such as premature babies or those with respiratory conditions.

If parents notice persistent or severe drops in their baby’s oxygen levels during sleep, it is important to consult a healthcare professional for further evaluation and guidance.

Babies at higher risk of experiencing drops in oxygen levels during sleep:

  • Premature babies
  • Babies with respiratory conditions

In conclusion, it is important for parents and caregivers to be aware that baby oxygen levels can drop while sleeping. Taking necessary precautions such as ensuring a safe sleep environment and regularly monitoring the baby’s breathing can help prevent any potential risks and ensure their well-being during sleep.

Is it normal for baby’s oxygen to drop sleeping?

Our research showed that the average oxygen saturation level of infants between 24 to 48 hours old is around 92% to 93%, and this remains consistent regardless of their level of activity. As the infants grow older, there seems to be a slight increase in oxygen saturation levels during awake periods, ranging from 93% to 94%. On the other hand, oxygen saturation during sleep either remains unchanged or slightly decreases.

What oxygen level is too low for a child when sleeping?

In children, if their oxygen saturation drops to 90% or lower for five minutes or longer, it may be considered sleep-related hypoxemia. This condition is usually caused by another underlying health issue.

What o2 level is too low for a baby?

Therefore, at what oxygen level is it considered too low for a baby? If a baby’s oxygen saturation levels fall below 90%, it is considered too low and may need to be treated.

When should I take my baby to the ER for low oxygen?

If you observe a child using additional muscles to breathe or breathing rapidly, it indicates that they are experiencing difficulty in breathing and immediate medical attention is required.

How accurate is Owlet oxygen level?

In both research studies, the Owlet Smart Sock demonstrated outstanding performance and met the accuracy requirements set by the industry and regulatory standards for pulse oximetry. The first study utilized direct arterial blood gas measurements, which are considered the most reliable method for testing the accuracy of pulse oximeters.

Does Owlet alert when oxygen is low?

Indeed! The Smart Sock maintains communication with the Base Station even if there is a Wi-Fi interruption, and it will alert you through visual and auditory cues if your baby’s heart rate or oxygen levels fall below the predetermined thresholds.
