Usage notes
The spelling "hypercapnea" is occasionally seen in published medical articles (44 results in a PubMed search in 2016), but it is not entered in major dictionaries and is not tied to any etymology that involves the -pnea suffix. It is a misspelling by writers who misunderstand that the word hypercapnia does not end in the same suffix that apnea ends in.
