A term newborn is admitted to the neonatal unit with positive pulse oximetry screen1 and tachypnoea. The respiratory rate is 70 breaths/min but there are no other signs of respiratory distress. The preductal pulse oximeter oxygen saturations (SpO2) are 91% and postductal SpO2 are 90% in room air. The baby is commenced on low-flow oxygen at 0.05 L/min, which improves both preductal and postductal SpO2 to 95%. Following this, the baby undergoes a chest radiograph which reveals a left-sided pneumothorax with no significant lung collapse or mediastinal shift. As this is an incidental finding and the baby shows no clinical or radiological signs of tension pneumothorax, you question the need to treat with higher concentration oxygen therapy as has previously been routine practice.
Structured clinical question
In term and late preterm neonates (≥34 weeks) with spontaneous pneumothorax (SP) without clinical or radiological signs of tension (patient), is high-concentration oxygen therapy (intervention) more effective than …
