Single-use, lightweight, and low-profile N₂O/O₂ sedation nasal hoods/masks. Designed to form fit comfortably over the patient’s nose and provide the clinician with easy, unobstructed access to the oral cavity. Lightweight tubing reduces drag and pull with patient movement and diminishes mask displacement. Translucent and clear mask shows patient is properly breathing through his/her nose. Contoured design around mask provides a good seal to minimize ambient N₂O and gas flow into patient’s eyes.
