1. A nasal interface assembly for providing ventilation gas, comprising:

  • (a) a tubular manifold adapted to be positioned inferiorly to the nostrils and superior to the mouth comprising;

    (1) an axially tubular structure comprising compound arcuate curves curving bilaterally from a manifold midline in a lateral and posterior direction, (2) a left lateral end and a right lateral end, (3) at least two gas flow openings on the superior side of the manifold, and (4) and a closure connected to the one lateral end;

    (b) a pair of tubular nasal cushions each comprising a proximal end base attached to one of the at least two gas flow openings, and each extending to a distal end adapted to impinge with and seal against the nostrils;

    (c) a ventilation gas supply assembly comprising a distal end adapted to connect to the lateral end of the manifold opposite the lateral end connected to the closure, the connection adapted to rotate in at least one plane, and a proximal end adapted to attach to a ventilator;

    (d) a head strap assembly; and

    (e) a connector connecting the head strap assembly to the manifold, the connector comprising two movable connections, wherein a first movable connection between the manifold and connector allows rotation of the manifold cross section in the sagittal plane, and a second movable connection between the head strap and connector allows pivoting of the head strap in the inferior-posterior direction.
