Respiratory distress syndrome is a condition that predisposes an infant to this condition.
<h3>What is 
Respiratory distress syndrome?</h3>
A respiratory condition that affects breathing in neonates. One of the most frequent issues with premature neonates is respiratory distress syndrome (RDS), formerly known as hyaline membrane disease.
A deficiency in pulmonary surfactant is the root cause of RDS. After the 26th week of pregnancy, in the third trimester, a fetus's lungs begin to produce surfactant. A frothy material called surfactant maintains the lungs' complete expansion so that neonates can breathe in air as soon as they are born.
The majority of ARDS cases, however, are caused by a small number of prevalent conditions; among patients in medical intensive care units, these conditions are pneumonia, sepsis, and aspiration.
Acute respiratory distress syndrome (ARDS) symptoms are:
- severe dyspnea or shortness of breath.
 - hurried and difficult breathing.
 - muscular soreness and extreme exhaustion.
 - Confusion.
 - quick heartbeat.
 - Due to low blood oxygen levels, fingernails and lips have a bluish appearance.
 - chest discomfort and coughing.
