Which of the following is not part of scoring pediatric obstructive sleep apnea?

• A. Missed respirations associated with arousal, awakening, or desaturation of 3% or more
• B. A duration of two or more missed respirations
• C. Inspiration effort that continues or increases during an apneic period
• D. A 90% or more decrease in amplitude for 90% of events, compared to baseline

Answer: (A)

In pediatric scoring, obstructive events are defined as apneas or hypopneas with specific criteria. An apnea is a drop in airflow for at least two consecutive breaths with continued or increased respiratory effort, signaling obstruction. The desaturation threshold of 3% is used to count hypopneas, not apneas. So a description of missed respirations accompanied by arousal or a 3% or greater desaturation aligns with hypopnea criteria rather than apnea criteria, making it not part of scoring pediatric obstructive apnea itself. The other descriptions fit apnea or obstructive patterns: two or more missed breaths defines an apnea, continued inspiratory effort during an apneic period indicates obstructive rather than central apnea, and amplitude-related criteria are used in hypopnea scoring within pediatric guidelines.
