Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
sufflātĭo (subfl-), ōnis, f. [sufflo], a blowing or puffing up, inflation (Plinian): bullantium aquarum, Plin. 9, 7, 6, § 18: praedurum est sufflatione viventibus, id. 9, 29, 46, § 86.
