As our intent will be to study infants for whom hospital stay is prolonged as a result of presumed apnea of prematurity, exclusion criteria will include: (1) comorbidities associated with an increased risk of apnea, including neurologic abnormalities such as congenital CNS malformations, seizures, or intracranial bleeds, anatomic abnormalities of the airway, significant congenital heart disease, residual lung disease requiring respiratory support, infectious disease including sepsis, pneumonia, or meningitis, chromosomal abnormalities, and drug withdrawal; (2) prolonged hospitalization for an indication other than apnea, bradycardia and/or oxygen desaturation such as feeding immaturity, temperature instability, or phototherapy; (3) transfer to an outside hospital; (4) provider concern with caregiver ability to safely operate and comply with home monitor use.
