Abstract
A tuneable expiration positive airway pressure (TEPAP) apparatus () comprises an entrainment valve () and a module (), fluidly coupled with an outlet port () of the entrainment valve, for tuning an inspiration-to-expiration pressure transition of the breath cycle. The entrainment valve () includes a housing (), an upstream inlet port (), a downstream outlet port (), and a valve (). The valve () enables inspiration airflow between an exterior the housing () and the inlet port () during inspiration and prevents expiration airflow between the inlet port () and the exterior of the housing () during expiration. The tuning module () facilitates at least one rate-of-change in pressure of the inspiration-to-expiration pressure transition that is non-instantaneous. The at least one non-instantaneous rate of change in pressure is selected from among different non-instantaneous rates-of-change in pressure of the inspiration-to-expiration pressure transition.
