Oxygen Levels For Newborns: Nclex Normal Range Guide

Oxygen levels in newborns are a critical aspect of neonatal care and require careful monitoring to ensure optimal health outcomes. Newborns, particularly those born prematurely, may have underdeveloped lungs or underlying health conditions that necessitate close surveillance of their oxygen saturation levels. The normal oxygen saturation range for newborns is typically between 93% and 97%, with deviations from this range potentially indicating hypoxia or other respiratory issues. Various methods exist to deliver oxygen therapy to newborns, including oxygen hoods, nasal cannulas, and ventilators, each with its own advantages and considerations. Understanding the normal oxygen levels for newborns is essential for healthcare professionals, especially nurses, to identify and address any deviations promptly and provide effective care.

Oxygen saturation levels for newborns

Oxygen saturation levels are a crucial indicator of a newborn's health, and maintaining normal levels is essential for their well-being. Newborns require adequate oxygen levels in their blood to ensure the proper functioning of their cells and organs.

Normal Oxygen Saturation Levels:

Normal oxygen saturation levels for newborns range from 95% to 100%. This means that their blood is fully saturated with oxygen, ensuring optimal cellular function.

Methods of Oxygen Delivery:

• Oxygen Hood or Head Box: A plastic dome or box with warm, moist oxygen is placed over the baby's head. It may include a device to measure oxygen intake.
• Nasal Cannula: A thin, soft plastic tube with prongs that gently fit into the baby's nose to deliver oxygen. Some oxygen may escape through the sides.
• Nasal CPAP System: Continuous positive airway pressure helps keep airways and lungs open and is used for babies needing more support.
• Ventilator: A breathing machine delivers increased oxygen and breathes for the baby when necessary.

Monitoring Oxygen Levels:

It is crucial to closely monitor a newborn's oxygen levels, as too much or too little can be harmful. Healthcare providers carefully balance oxygen delivery to prevent complications.

Risks of Too Much or Too Little Oxygen:

• Too Little Oxygen: Cells may not function properly, leading to potential cell death and inadequate growth. Organs such as the brain and heart may be injured.
• Too Much Oxygen: Lung damage can occur, and for very premature babies, there is a risk of problems in the brain and eyes. Specific heart conditions may also require lower blood oxygen levels.

Reference Values:

Reference values for pulse oximeter saturations (SpO2) in term and preterm infants show that during normal breathing, 95% of infants maintain SpO2 at or above 93-97%, depending on age.

Oxygen Therapy:

Oxygen therapy may be required for babies with heart or lung problems to ensure they receive adequate oxygen levels in their blood. This therapy can be life-saving and is carefully monitored to balance the risks and benefits.

In summary, maintaining normal oxygen saturation levels is critical for newborns, and healthcare professionals play a vital role in ensuring their well-being by carefully monitoring and adjusting oxygen delivery as needed.

Risks of oxygen therapy

Oxygen therapy is often necessary for newborns with heart or lung problems to ensure they receive normal levels of oxygen in their blood. However, there are several risks associated with oxygen therapy that can affect newborns:

• Too much or too little oxygen can be harmful. Insufficient oxygen can lead to decreased energy production, causing cells to function poorly or die. This can result in improper growth and injury to developing organs, including the brain and heart.
• Lung damage can occur with excessive oxygen therapy. For very premature babies, high levels of oxygen in the blood can also lead to problems in the brain and eyes.
• Babies with certain heart conditions may require lower levels of oxygen in the blood.
• Cold exposure is another risk, as oxygen therapy can lower a baby's temperature. To mitigate this, the oxygen is often heated and humidified.
• Irritation and infection can occur with the use of dry oxygen through nasal cannulas or nasal CPAP devices. This can cause cracked skin, bleeding, or mucus plugs in the nose, increasing the risk of infection.
• Skin breakdown around the nose may happen if nasal CPAP devices are not fitted properly or shift during use due to their wide nasal prongs.
• Mechanical ventilators carry their own set of risks, which healthcare providers must carefully balance with the benefits of the baby's breathing support.

It is crucial for healthcare providers to closely monitor and balance the amount of oxygen administered to newborns, considering their unique needs and potential risks.

Oxygen delivery methods

Newborns with acute or chronic lung disease may require additional inspired oxygen if their oxygen saturation levels fall below the recommended threshold. The normal oxygen saturation range for a healthy term infant is between 93% and 97%.

There are several methods of delivering oxygen to a newborn, depending on their condition and whether they can breathe independently. Here is a detailed description of each method:

Oxygen Hood or Headbox

An oxygen hood is a plastic dome or box filled with warm, moist oxygen. It is placed over the baby's head to deliver the required oxygen. This method is suitable for babies who can breathe on their own but require additional oxygen. The hood often includes a device to measure the exact amount of oxygen the baby receives.

Nasal Cannula

A nasal cannula is a thin, soft plastic tube with prongs that gently fit into the baby's nose. Oxygen flows through the tube, but some may escape from the sides, which means the baby might not always receive the intended amount. This method is an alternative to using an oxygen hood.

Nasal CPAP (Continuous Positive Airway Pressure) System

The nasal CPAP system delivers oxygen-containing air at higher pressure to keep the airways and lungs open. It is often used for premature babies who struggle to keep their lungs inflated. The air flows into the baby's nose through tubes connected to soft nasal prongs or a small mask. Nasal CPAP provides a tighter fit compared to a nasal cannula, resulting in less oxygen escape.

Ventilator or Breathing Machine

In cases where a newborn is too weak, tired, or sick to breathe on their own, a ventilator may be necessary. This machine delivers increased oxygen and can provide breaths to the baby through a tube placed in their windpipe. With a ventilator, the baby typically receives a more precise amount of oxygen as intended.

Monitoring oxygen levels

Oxygen levels are a vital indicator of an infant's health, and maintaining normal oxygen levels is crucial for their well-being. Nurses play a critical role in ensuring that newborns receive the necessary oxygen therapy and that their oxygen levels are carefully monitored. Here are some detailed instructions and considerations for monitoring oxygen levels in newborns:

Understanding Oxygen Levels:

• Oxygen is essential for the proper functioning of cells in the body. The air we breathe typically contains 21% oxygen, and we can receive up to 100% oxygen in the form of pure oxygen.
• Newborns with heart or lung problems may require increased amounts of oxygen to achieve normal oxygen levels in their blood.
• Oxygen saturation levels below 93-97% may indicate the need for additional inspired oxygen, depending on the infant's age.

Methods of Oxygen Delivery:

• Oxygen Hood or Head Box: This method is used for babies who can breathe on their own but need extra oxygen. It involves placing a plastic dome or box with warm, moist oxygen over the baby's head.
• Nasal Cannula: A thin, soft plastic tube with soft prongs that gently fit into the baby's nose to deliver oxygen. However, some oxygen may escape through the sides.
• Nasal CPAP (Continuous Positive Airway Pressure) System: Used for babies who need more support than a hood or nasal cannula but can still breathe on their own. It delivers oxygen-containing air under higher pressure to keep the airways and lungs open.
• Ventilator: A breathing machine that may be necessary for babies who cannot breathe on their own. It can provide extra pressure using the infant's own breaths or deliver breaths if the baby is too weak or sick.

Risks of Oxygen Therapy:

• Too much or too little oxygen can be harmful to newborns. Insufficient oxygen can lead to decreased energy production and cell dysfunction or death.
• Excessive oxygen can also cause injury, particularly to the lungs, brain, and eyes of premature babies.
• Healthcare providers must carefully monitor and balance the amount of oxygen delivered to avoid these risks.

Monitoring and Adjustments:

• Vital Signs: Regularly monitor the infant's vital signs, including respiratory rate, heart rate, and blood oxygen saturation levels.
• Oxygen Saturation Targets: Maintain oxygen saturation levels within the normal range for newborns, typically above 93-97%. Adjust oxygen delivery methods or settings as needed to achieve and maintain these targets.
• Laboratory Tests: Perform laboratory tests, such as blood gas analyses, to assess the infant's oxygen levels and make informed clinical decisions.
• Observation and Response: Closely observe the infant for any signs of distress or improvement. Adjust oxygen delivery methods or settings accordingly, in collaboration with the healthcare team.

Nursing Considerations:

• Comfort and Positioning: Ensure the infant is comfortable and properly positioned during oxygen therapy.
• Skin Care: Monitor the skin around the nose and mouth for any signs of irritation or breakdown due to dry oxygen or ill-fitting nasal devices.
• Temperature Control: Maintain a suitable temperature for the oxygen to prevent the infant from getting too cold. Warm and humidify the oxygen as needed.
• Infection Control: Follow infection control practices, especially when using nasal cannulas or CPAP devices, to reduce the risk of infection.
• Family Education: Educate the family about the importance of oxygen therapy, monitoring, and any necessary home care procedures.

By following these guidelines and staying vigilant, nurses can effectively monitor oxygen levels in newborns and ensure they receive the oxygen they need for healthy development.

Signs of oxygen deficiency

The normal oxygen saturation level for a full-term, healthy baby is 95-100%. Preterm babies usually have lower oxygen saturation levels due to their immature lungs, but their levels should still be above 90%. Oxygen levels below 90% in babies are considered low and may require treatment.

• Cyanosis: A bluish tint to the skin due to constricted blood vessels attempting to increase oxygenation.
• Apnea: A pause in breathing for 20 seconds or longer, often caused by respiratory distress.
• Bradycardia: A heart rate of fewer than 60 beats per minute.
• Seizures: These can be caused by a lack of oxygen to the brain.
• Lethargy: A state of tiredness and lack of energy caused by oxygen deprivation.
• Abnormal skin colour: Skin may appear gray, pale, or blue due to a lack of oxygen in the blood.
• Weak or absent breathing: Difficulty breathing or a complete absence of breathing efforts.
• Acidosis: Excess acid in the baby's blood due to impaired cell function.
• Problems with blood clotting: Lack of oxygen can impair the blood's ability to clot properly.
• Signs of inadequate blood circulation: This may include cold extremities or prolonged capillary refill.
• Stool or meconium in the amniotic fluid: Meconium aspiration can lead to respiratory distress and low oxygen levels.
• Urinary problems: The baby may have difficulty urinating or may not urinate at all.

It is important to carefully monitor a newborn's oxygen levels and watch for these signs of oxygen deficiency to ensure their health and well-being.
