Stertor
A stertor is a respiratory sound characterized by heavy snoring or gasping. It is caused by partial obstruction of airway above the level of the larynx and by vibrations of tissue of the naso-pharynx, pharynx or soft palate (this distinguishes it from stridor, which is caused by turbulent air flow below or in the larynx). It is low-pitched, non-musical, and occurs during the inspiratory phase only. In general terms it is a snoring or snuffly sound. Stertorous breathing will be audible during the post-ictal phase after a tonic-clonic seizure.
Causes
- Loss of nervous control of the pharynx, soft palate, particularly from damage for instance by stroke or tumor to the vagus and hypoglossal cranial nerves
- Obstructive sleep apnea
- Upper airway resistance syndrome
gollark: To create RAM kittens, all you need to do is `ADD` the ASCII value of each character into a temporary register, `POKE` them into the right memory location (using the per-instruction `POKE` offset, probably), and then do that in a loop.
gollark: I should probably implement arithmetic instructions then a basic assembler, I guess, because hand-writing machine code is unpleasant.
gollark: What? No. This doesn't really need jumps, except possibly to run it repeatedly.
gollark: Well, it would just be a bunch of POKEs at consecutive memory addresses.
gollark: So, hmm, what instructions should I add... other than basic arithmetic and bitops I guess.
