Acidosis Respiratory Newborns

Respiratory acidosis of newborns

Respiratory acidosis of newborns is a violation of the acid-base balance, characterized by a decrease in blood pH, caused by excess carbon dioxide in the newborn’s body.

Reasons for development:

  1. Immaturity of the newborn's respiratory center, which leads to inadequate breathing and accumulation of CO2.

  2. Congenital malformations of the lungs and airways (for example, pulmonary hypoplasia).

  3. Difficulty in nasal breathing due to rhinitis, polyps.

  4. Aspiration of amniotic fluid.

  5. Infectious and inflammatory diseases of the lungs.

Clinical manifestations:

  1. Rapid shallow breathing

  2. Cyanosis

  3. Tachycardia

  4. Excitement, convulsions

  5. Depression of the respiratory and vasomotor centers

Diagnosis is based on the gas composition of the blood - a decrease in pH, hypoxemia, and hypercapnia are detected.

Treatment is aimed at eliminating the causes of acidosis and maintaining breathing. Oxygen therapy and mechanical ventilation are carried out. If necessary, use alkaline solutions to normalize the acid-base state.

The prognosis depends on the severity of the condition and the effectiveness of therapy. Timely treatment can prevent the development of severe complications and death.



Neonatal respiratory acidosis, also known as neonatal respiratory acidosis, is a medical condition characterized by low pH levels in the blood of a newborn baby caused by problems with respiratory function. This is a serious condition that requires medical attention and monitoring.

During normal respiratory function of a newborn baby, oxygen enters the lungs through the respiratory tract, and carbon dioxide is removed from the body. However, newborns may have problems that interfere with this process, resulting in respiratory acidosis.

The most common cause of respiratory acidosis in newborns is insufficient oxygen reaching the lungs or problems removing carbon dioxide. It can be caused by a variety of factors, including respiratory infections, pulmonary distress syndrome (PDS), abnormalities of the respiratory system, and premature or difficult labor.

Symptoms of respiratory acidosis in newborns may vary depending on the degree of respiratory impairment. Common signs may include rapid and shallow breathing, cyanosis (blueness) of the skin or mucous membranes, weakness, depression and malnutrition.

Various tests are performed to diagnose respiratory acidosis in newborns, including blood tests for pH levels, blood gases, and blood oxygen levels. Additional tests such as chest x-ray and ultrasound may be used to identify causative factors.

Treatment of respiratory acidosis in newborns is aimed at eliminating the causative factors and maintaining normal levels of oxygen and pH in the blood. In some cases, artificial ventilation may be required using a special machine to provide sufficient oxygen and remove carbon dioxide.

The prognosis depends on the severity of the condition and the timeliness of treatment. With timely and adequate medical care, most newborns recover completely and have no long-term consequences. However, in severe cases, respiratory acidosis can lead to complications such as organ damage and developmental delays.

In conclusion, neonatal respiratory acidosis is a serious medical condition caused by problems with respiratory function in newborns. Correct diagnosis and timely treatment play a decisive role in the prognosis and outcome of this condition. Parents and medical personnel should be alert to possible symptoms and seek immediate medical attention if they are detected.
