Inside Newborn Breathing

Understanding and Identifying Newborn Breathing Patterns, Noises, and Distress

Newborns exhibit distinct breathing patterns that differ from older children and adults, characterized by variations in pace and depth. It is common for newborns to experience short pauses in breathing (up to 10 seconds), which generally do not indicate a problem. These patterns, including the irregular rhythms and the phenomenon of periodic breathing—cycles of rapid breaths followed by pauses—are part of the normal respiratory development in newborns, as long as the pauses do not exceed 20 seconds.

The range of noises newborns make, from soft whistles to snorts or grunts, are typically normal manifestations of a respiratory system that is still maturing. Snuffles, often caused by small nasal passages, may resolve over time or with gentle suctioning.

Certain noises may indicate issues:

Wheezing, a high-pitched sound during exhalation, can suggest narrowed airways.
Stridor, a harsh vibrating noise during inhalation, points to a blockage near the vocal cords.
Grunting with each breath might indicate difficulty in expelling air from the lungs.

Signs of respiratory distress include an increased effort to breathe, observable through flaring nostrils or see-saw movements (where the chest moves in while the stomach pushes out). Persistent cyanosis, a bluish tint on lips or fingertips, even in a calm state, indicates inadequate oxygen levels.

In understanding these breathing patterns and noises, it becomes possible to recognize the typical respiratory behavior of newborns. Awareness of what constitutes normal breath sounds and movements, and the early signs of distress, is essential for observing newborns as they develop.

Typical Rates and Transient Tachypnea in Newborn Breathing

Newborns generally breathe about 40 to 60 times per minute, a rate that is considered normal for infants but is higher than that of adults. However, some newborns may develop a condition known as transient tachypnea of the newborn (TTN), characterized by an even faster breathing rate.

Transient tachypnea occurs when fluid remains in the baby's lungs after birth. This condition is more frequently observed in babies delivered via cesarean section, as these newborns miss out on the squeezing process during vaginal birth that helps expel fluid from the lungs. Symptoms of TTN include:

Rapid breathing at a rate exceeding 60 breaths per minute
Grunting noises
Flaring nostrils
Visible chest retractions where the ribs are evident during breathing efforts

Most instances of TTN resolve within three days as the extra fluid is naturally cleared from the lungs. Treatment during this period typically involves supporting the affected newborns, possibly including:

Providing oxygen to maintain adequate levels
Employing other methods to facilitate comfortable breathing

This information offers an overview of typical breathing rates in newborns and the occurrence and handling of transient tachypnea.

Newborn Breathing Issues: Infections, Nasal Congestion, and Allergies

Newborns can face many challenges as they adapt to breathing outside the womb, including infections, nasal congestion, and allergies. Each of these conditions can impact a baby's ability to breathe comfortably and efficiently.

Infections

Respiratory infections like the common cold or more serious conditions such as Respiratory Syncytial Virus (RSV) can lead to significant breathing issues in newborns. Symptoms to observe may include:

Rapid breathing
Wheezing
Coughing
A bluish tint around the lips, which can indicate oxygen deprivation.

Nasal Congestion

Newborns cannot clear their own nasal passages, making them particularly susceptible to blockages caused by mucus build-up. Such congestion, while it might not seem severe, can disrupt feeding and sleeping patterns. Methods often utilized include:

Saline drops
Gentle suction with a bulb syringe

Allergies

Though less common in very young infants due to minimal exposure to potential allergens, allergies can still cause breathing difficulties. Symptoms may include:

Stuffiness
Sneezing
Coughing
Skin rashes after exposure to certain foods (through breastfeeding), pets, or dust mites, among others.

Identifying triggers is beneficial for managing this condition.

Each situation involving newborn health issues, including those affecting breathing, is unique.

Safe Sleeping Practices for Newborn Breathing

Ensuring newborns sleep safely is crucial for their health and well-being, particularly in promoting good breathing. This section highlights important measures to support a newborn's respiratory health during sleep.

Placing a baby on their back to sleep, for both naps and nighttime, keeps airways open and significantly reduces the risk of Sudden Infant Death Syndrome (SIDS). It is important to avoid placing babies on their stomachs or sides, as this can compromise their ability to breathe freely.
A firm mattress in a safety-approved crib, covered with a fitted sheet, is recommended. Soft surfaces, like couches, pillows, blankets, or loose bedding, can obstruct an infant's nose and mouth if they turn face-down, while a firm surface ensures that their breathing remains unobstructed even if they move during sleep.
Ensuring there are no soft objects or loose bedding in the crib is crucial. Toys, pillows, quilts, and bumper pads pose suffocation risks and could interfere with airflow around a baby’s face.
Keeping the baby’s crib in the same room, but not the same bed, for at least six months is beneficial for monitoring and feeding during the night, as sharing beds can increase risks of suffocation or overheating, potentially disrupting normal breathing patterns.

Following these guidelines each time a newborn is put down to rest is essential for maintaining healthy breathing while asleep, supporting overall well-being.

When to Seek Medical Help for Newborn Breathing Concerns

Newborns exhibit unique breathing patterns that can cause concern for new parents. It is typical for newborns to breathe in an irregular manner, taking shallow, quick breaths followed by deeper ones, or making brief pauses in their breathing. While often this is considered normal, certain signs may indicate the need for attention.

Observing the following warning signs is important:

Fast Breathing: A baby taking more than 60 breaths per minute while in a calm and resting state might be experiencing distress.
Grunting with Each Breath: This could indicate difficulties in breathing adequately.
Flaring Nostrils: An observable widening of the nostrils during breathing may indicate an increased effort to breathe.
Retractions: The sinking in deeply of the skin between the ribs, above the collarbone, or around the neck during inhalation could be a sign of difficulty in drawing a breath.
Blue Coloring around Lips or Face (Cyanosis): This is an indication of oxygen deprivation and signifies the need for attention.

It is beneficial to be observant of a baby's breathing pattern and to be aware of the signs that may require attention. Regular check-ups or immunization visits provide opportunities to discuss any concerns about a baby’s breathing pattern. Being informed enables a comprehensive understanding of a child’s health needs.
