Understanding TTN: Fast Breathing in Newborns


The arrival of a newborn is a joyous occasion, but it can also be a time of worry for new parents. One common concern is rapid breathing in their baby, which can be a symptom of various conditions. One such condition, Transient Tachypnea of the Newborn (TTN), might sound scary, but it’s important to understand that it’s usually a temporary and treatable issue.

This blog post aims to provide comprehensive information about TTN, empowering parents and caregivers with knowledge to navigate this situation with confidence. We’ll delve into the causes, symptoms, diagnosis, treatment, and long-term outlook, so you can feel informed and supported.

What is TTN?

Transient Tachypnea of the Newborn, also known as “wet lungs” or “Type II respiratory distress syndrome,” is a self-limiting respiratory condition affecting newborns shortly after birth. It manifests as rapid breathing (tachypnea) due to a delay in the absorption of fluid from the baby’s lungs. This fluid is present naturally before birth, allowing the baby to breathe in the amniotic sac. However, after birth, the lungs need to adapt to air breathing, and any leftover fluid can cause breathing difficulties.


What causes TTN?

The exact cause of TTN is unknown, but several factors are thought to contribute:

Delivery factors: Cesarean delivery, especially without labor, and maternal diabetes seem to increase the risk.

Premature birth: While TTN is more common in full-term babies, it can also occur in premature infants.

Lung immaturity: Certain factors like prematurity or maternal medical conditions might contribute to underdeveloped lungs, leading to delayed fluid clearance.

What are the symptoms of TTN?

Symptoms of TTN usually appear within the first few hours of life and may include:

Rapid breathing: Over 60 breaths per minute, often described as shallow and fast.

Grunting sounds: Audible noises with breathing, especially during exhalation.

Flaring nostrils: Wider than usual nostrils due to increased breathing effort.

Retractions: Skin pulling in between the ribs or under the ribcage with each breath.

Cyanosis: Bluish tint to the skin, especially around the lips and nail beds, due to low oxygen levels.

How is TTN diagnosed?

Doctors diagnose TTN based on the baby’s symptoms, medical history, and physical examination. Additional tests might be conducted to rule out other causes, such as:

Chest X-ray: To visualize the lungs and check for fluid buildup.

Blood tests: To assess oxygen and carbon dioxide levels.

Echocardiogram: To rule out heart problems.

How is TTN treated?

The good news is that TTN is usually a self-resolving condition. Most babies improve within 24-48 hours with supportive care, which may include:

Supplemental oxygen: To ensure adequate oxygen levels until the lungs clear the fluid.

Nasal cannula or mask: To deliver oxygen comfortably to the baby.

Monitoring vital signs: Closely tracking breathing rate, oxygen levels, and other vitals to assess progress.

Positioning: Supporting the baby’s head slightly elevated to aid breathing.

Fluid restriction for the mother: In some cases, restricting the mother’s fluid intake during labor can help reduce the risk of TTN in the baby.

How is TTN different from RDS?

Transient tachypnea of the newborn (TTN) and respiratory distress syndrome (RDS) are both respiratory conditions that can affect newborn babies, but they have different causes and characteristics.

TTN (Transient Tachypnea of the Newborn):

Cause: TTN is primarily caused by delayed absorption of fetal lung fluid. During birth, the newborn may not fully clear this fluid from their lungs, leading to respiratory distress.

Onset: Symptoms of TTN typically appear shortly after birth, often within the first few hours, and usually resolve within 48 to 72 hours after birth as the excess fluid is absorbed.

Symptoms: The main symptom of TTN is rapid breathing (tachypnea), often with grunting or flaring of the nostrils. The baby may also have mild retractions (visible inward movement of the chest wall during breathing).

Treatment: TTN usually resolves on its own without the need for specific treatment. However, supportive care such as oxygen therapy or CPAP may be provided if necessary to help the baby breathe more comfortably.

RDS (Respiratory Distress Syndrome):

Cause: RDS is caused by a deficiency of surfactant, a substance that helps keep the air sacs in the lungs open. Surfactant deficiency leads to collapsed air sacs and difficulty breathing.

Onset: Symptoms of RDS typically appear shortly after birth, often within the first few minutes to hours, especially in premature infants whose lungs have not yet produced sufficient surfactant.

Symptoms: The main symptoms of RDS include rapid, shallow breathing, retractions (visible inward movement of the chest wall during breathing), grunting, and cyanosis (bluish discoloration of the skin).

Treatment: Treatment for RDS often involves providing supplemental oxygen and administering exogenous surfactant to help improve lung function. In severe cases, mechanical ventilation may be necessary to support breathing.

In summary, while both TTN and RDS can cause respiratory distress in newborns, they have different underlying causes, onset times, and treatment approaches. TTN is typically a transient condition related to delayed clearance of lung fluid, whereas RDS is primarily caused by surfactant deficiency, particularly in premature infants.


What medication is used for TTN?

TTN, or transient tachypnea of the newborn, is a condition characterized by rapid breathing in newborns shortly after birth. It is often caused by delayed absorption of fetal lung fluid. In most cases, TTN resolves on its own without the need for medication. However, in some cases where the symptoms are severe or if there are complications, healthcare providers may administer oxygen therapy or use a continuous positive airway pressure (CPAP) machine to help the baby breathe more comfortably.

Medications are not typically the first-line treatment for IT. However, if there are complications such as respiratory distress or infection, healthcare providers may prescribe antibiotics or other medications as needed. The specific medications used would depend on the individual circumstances and the underlying cause of the symptoms. It’s important for parents to consult with healthcare professionals for the appropriate treatment plan for their newborn.

What is the long-term outlook for babies with TTN?

The vast majority of babies with TTN experience a full recovery with no long-term consequences. They usually outgrow the condition within a few days and go on to develop normally. However, it’s crucial to follow the doctor’s advice and seek immediate medical attention if the baby’s symptoms worsen or persist.

Additional Tips for Parents and Caregivers:

Stay informed: Educate yourself about IT and its symptoms to manage concerns and ask informed questions during doctor visits.

Communicate with your doctor: Share any observations about your baby’s breathing or behavior to ensure prompt diagnosis and treatment.

Seek support: Don’t hesitate to reach out to healthcare professionals or support groups for reassurance and guidance.

Trust your instincts: If you feel something is wrong with your baby, even if symptoms seem mild, advocate for their well-being and seek medical help.

What is the duration of TTN?

IT, which stands for Transient Tachypnea of the Newborn, typically lasts for 12-24 hours, although it can persist for up to 72 hours in some cases.

Here’s a breakdown of the duration:

Most babies: Recover within 12-24 hours.

Some babies: May take up to 72 hours to recover.

Babies born early: Might have a longer duration, especially if they had very high breathing rates at birth.

It’s important to note that IT should resolve within a few days. If your baby’s symptoms persist for longer than 72 hours, it’s crucial to seek medical advice to rule out other potential causes of respiratory distress.

Transient Tachypnea of the Newborn, while initially concerning, is often a temporary and treatable condition. With proper understanding and support, most babies with IT make a full recovery and enjoy healthy development. By staying informed, communicating with healthcare professionals, and trusting your instincts, you can navigate this situation with confidence and ensure your baby
