Abstract
A nasal mask for use in respiratory therapy is provided with one or more vent ports which are adjustable for directing vented air in a direction which is most comfortable to the patient. By providing adjustable vent ports, the patient can adjust the direction of the vented air to a position that best accommodates the patient. Each vent port can be in the form of a passage in a member which is mounted to rotate in an opening through the mask. The member may be rotated in the opening to change the direction of air flowing through the passage or passages. The member may be designed to rotate about a fixed axis relative to the mask, or it may be spherical and designed to rotate in any direction. Preferably, a knob or tab is provided for grasping to facilitate manually adjusting the vent port orientation.
