Directionally supported by literature on HME/anaesthetic gas humidification research dating to the late 1970s (Chalon et al., 1979) Chalon J, Loew DA, Malebranche J. Effects of dry anesthetic gases on tracheobronchial ciliated epithelium. Anesthesiology. 1972 Sep;37(3):338-43. doi: 10.1097/00000542-197209000-00010. PMID: 4115208.
