title: Validation of a Suprasternal Pressure Sensor for Sleep Apnea Classification in Children.
abstract: The recognition and characterization of respiratory events is crucial when interpreting sleep studies. The aim of the study was to validate thePneaVoXsensor, which integrates the recording of respiratory effort by means of suprasternal pressure (SSP), respiratory flow, and snoring for the classification of sleep apneas in children.
  
  
  
  Sleep recordings of 20 children with a median age of 7.5 (0.5-16.5) years were analyzed. Scoring of apneas according to the American Academy of Sleep Medicine (AASM) guidelines using nasal pressure, oronasal thermal sensor and respiratory efforts by means of respiratory inductance plethysmography (RIP), was compared to a scoring using thePneaVoXsensor and nasal pressure, without the oronasal thermal sensor nor RIP, during a dual blind study.
  
  
  
  The percentage of sleep time recording without artifacts was 97%, 97%, 87%, 65%, and 98% for the respiratory flow and SSP from thePneaVoXsensor, oronasal thermal sensor, nasal pressure, and RIP, respectively. As compared to the AASM scoring with RIP, sensitivity and specificity of the SSP for the scoring of central apneas were 75% and 99% for the first reader, and 70% and 100% for the second reader, respectively. Sensitivity and specificity for the scoring of obstructive apneas were 98% and 75%, and 100% and 70%, respectively. A significant number of apneas scored as central by RIP were scored as obstructive by the SSP.
  
  
  
  ThePneaVoXsensor has a high degree of scorability in children. ThePneaVoXsensor is a useful adjunct for characterizing apneas.
