My son is 6 and has quadripalegic CP, he is on a 24/7 feeding tube and listed NPO. Last week he had a bad head cold, but his mucus lessened and he hasn t had any meds since friday. Tonight he is much worse, heavy stridor breathing, and he has begun vomiting mucusy foam, which I ve seen before, except it is brown and not the normal yellowy/green. Any ideas, or should I just try him on some expectorant and decongestant and observe?

Summarized question: What causes mucous vomiting while suffering from quadriplegia?
