What is a “death rattle” and what causes it?

What is a stridor?
a high pitched wheezing that is caused by the obstruction of the trachea either by inflammation or an object. Just enough air passes the obstructed point to cause a high-pitched whining wheeze.
What causes stridor most often in children?
Croupe, a viral infection that causes the tracheal membranes to swell to a near-closed position. The wheeze is produced much like a wind instrument produces sound through a wooden reed.
