During resuscitation, a baby is responding to positive-pressure ventilation with a rapidly increasing heart rate. her heart rate and oxygen saturation suddenly worsen.she has decreased breath sounds on the left side and transillumination also reveals a bright glow on the left side.what is the most likely cause of this distress?

A pneumothorax is often called a collapsed lung. A left-sided pneumothorax takes place when the air leaks or escapes from the baby's lungs and gain entry into the space that is in between the two membranes, also known as the pleural cavity. As the air escapes through the chest wall and continues to build up in the pleural cavity, it will affect the lungs collapsed.

Further Explanation

Respiratory distress syndrome is one of the common causes of pneumothorax and it is very common in newborn babies, especially babies that are born premature (babies that are born too early)

The lungs of a premature baby lack the required substances needed for the lungs to stay open. This causes some distress because the tiny air sacs do not have what it takes to easily expand.

If a mechanical ventilator (breathing machine) is applied to place extra pressure on the baby’s lungs, it can burst the air sac.

Some other causes of Pneumothorax in babies include

Meconium aspiration syndrome
Pneumonia or lungs tissues that were not well developed

Also, some of the symptoms of pneumothorax in children include

Restlessness
Grunting
Nostril flaring
Pale
