{"terms":[
 {"term":"Stridor","kind":"define","source":"editor",
  "definition":"A harsh noise made by air forced through a narrowed upper airway. Heard on breathing in, the narrowing is above the thoracic inlet; on breathing out, below it; on both, at the glottis or just under it."},
 {"term":"Functional residual capacity","kind":"why","source":"editor",
  "definition":"The air left in the lungs at the end of a quiet breath out — the oxygen store a child draws on when they stop breathing. It is smaller per kilogram in children, and they use oxygen faster, which is why a child desaturates in seconds where an adult has a minute."},
 {"term":"Anion gap","kind":"define","source":"editor",
  "definition":"Sodium minus chloride and bicarbonate. It measures the acids a routine panel does not name; a wide gap says an acid has been added — ketones, lactate, a toxin — rather than bicarbonate simply being lost."},
 {"term":"Tripod position","kind":"caution","source":"editor",
  "definition":"Sitting forward on the hands with the chin pushed out and the mouth open. A child who has chosen this position has chosen the only one that keeps their airway open, and laying them flat or upsetting them can close it."}
