Abstract
Systems, apparatus, and methods for providing humidity in a positive airway pressure (PAP) device. In one embodiment, a humidifier is configured to periodically provide vapor to a flow of pressurized gas to produce flows of pressurized gas with added humidity. Each of the flows of pressurized gas with added humidity may be timed to reach a user interface primarily during a first portion of a breath cycle (e.g., during inspiration). Portions of the flow of pressurized gas that reach the user interface during a second portion of the breath cycle (e.g., during expiration) may include little or no added humidity.
