A Newborn Baby Exhibits Signs Of Respiratory Distress
A Newborn Baby Exhibits Signs Of Respiratory Distress Due To The Lack
A newborn baby exhibits signs of respiratory distress due to the lack of surfactant. She has signs of low oxygen and high carbon dioxide. Explain the following in depth: What is the role of surfactant, what cell secretes it, and when does the body start its production as well as when it is secreted? Why does the lack of surfactant result in respiratory distress? What type of acid-base disorder would the infant develop? How would the infant’s body compensate for the acid-base disorder? has to be 250 words apa format 2 citations.

The respiratory distress observed in this newborn is primarily due to surfactant deficiency, which plays a critical role in maintaining alveolar stability and efficient gas exchange. Pulmonary surfactant is a complex mixture of lipids and proteins secreted by alveolar type II epithelial cells in the lungs (Lourenço et al., 2018). Its primary function is to reduce surface tension within the alveoli, preventing alveolar collapse during exhalation and facilitating easier inflation during inhalation. Surfactant production begins late in fetal development, around the 24th to 28th week of gestation, with significant increases after the 32nd week, reaching sufficient levels near term to sustain effective respiration (Sweet et al., 2019).
In cases of surfactant deficiency, the alveoli tend to collapse, leading to decreased lung compliance and impaired gas exchange, resulting in hypoxemia and hypercapnia, as seen in this infant. The absence of surfactant increases surface tension, making it difficult for the newborn to expand the lungs, thereby causing respiratory distress syndrome (RDS). The underlying acid-base disorder in this case is respiratory acidosis, characterized by elevated carbon dioxide (CO2) levels due to hypoventilation, which lowers blood pH (Bhutta et al., 2020).
The infant’s body attempts to compensate through renal mechanisms by increasing bicarbonate reabsorption, striving to buffer the excess hydrogen ions. This metabolic compensation helps stabilize blood pH over time but may be insufficient if the underlying airway resistance persists (Kumar & Clark, 2021). Effective management, including surfactant therapy and respiratory support, is vital to improve gas exchange and correct acid-base imbalances in such neonates.
