Performing polysomnography in pre-school aged children: challenging parts of the procedure and risk factors for lead intolerance.

Purpose: Pediatric sleep apnea begins in toddlerhood when sleep is vital for neurocognitive development and rapid somatic growth. As polysomnography (PSG) can be challenging in this age group, this study described the first PSG for children aged 2 to 6 years old in regards to completion and risk-factors for intolerance.

Methods: Single center chart review in a pediatric-only hospital-based sleep center.
