Complications

Nasal Septal Erosion or Necrosis

• This is preventable when using appropriate sized prongs that are correctly positioned.

Pneumothorax

• Usually occurs in acute phase.
• It is uncommon (<5%).
• It usually results from the underlying disease process rather than positive pressure alone.
• It is not a contraindication to the use of CPAP.

Abdominal Distension from Swallowing Air

• This is benign
• Easily reduced with gastric drainage or aspiration

Nasal obstruction

• From improper prong placement or inadequate airway care
