The effect of humidity on the histologic lesions induced by high-frequency jet ventilation was investigated in 12 healthy cats. After 16 hours of ventilation, the appearance of the tracheal epithelium ranged from normal to necrotic. The damage was considerably more severe in the trachea of cats of the group ventilated without added humidity. Increasing the relative humidity to 63% at 24 C had a protective effect, but further increasing the relative humidity to 92% at 35 C did not appear to provide significantly more protection. The bronchi and distal airways had minimal, if any, damage in all groups. Copyright © 2018 The Board of Regents of the University of Wisconsin System
