ABSTRACT:
A nasal cannula for delivering respiratory gas to a neonatal infant includes a gas inlet configured to engage a respiratory conduit, a gas outlet configured to engage an expiratory conduit, and a pair of nasal prongs. The gases inlet and the gases outlet are in fluid communication via a low resistance path. Each of the nasal prongs is located substantially equidistant from, and in fluid communication with, the gases inlet, and substantially equidistant from and in fluid communication with, the gases outlet. The nasal prongs are juxtaposed directly in the low resistance path.
