Abstract
A hand-held positive expiratory pressure device is presented. A float is insertable into an internal chamber of a housing and is urged towards a sealing surface by a biasing member to restrict or prevent airflow through the internal chamber. A user exhaling through the device urges the float away from the sealing surface to allow fluid to flow through the internal chamber. An adjustable stop positioned in the internal chamber selectively adjusts the amount of force exerted by the biasing member on the float.
