Abstract
A system for adjusting a gas delivery mask is provided. The system may include a base, an arm pivotally coupled to the base, and an intermediate member slidably coupled to both the base and the arm. The arm may include a first threaded portion, and the intermediate member may include a second threaded portion coupled to the first threaded portion. Rotation of the second threaded portion relative to the first threaded portion may slide the intermediate member along the arm and relative to the base such that the arm pivots relative to the base.
