Abstract: A breathing apparatus with improved ergonomic aspects to more comfortably accommodate patients breathe while preventing their lungs from collapsing. The present breathing apparatus comprises an apparatus body having proximal and distal ends with at least one hollow passageway extending therebetween. A pair of nostril-engaging stems with generally D-shaped base configurations conform to the anatomy of patient's nostrils and a connector assembly having a rotatable mid portion is used at the apparatus body's distal end to allow moderate movement and thereby reduce torque applied to a patient's face.
