The compact system gives healthcare professionals control over the nitrous oxide concentration while allowing patients to receive the gas mixture as they breathe through the disposable breathing circuit.
Available in three configurations, Nitronox Plus gives healthcare professionals the flexibility to choose the system that best fits their practice needs:
The demand-flow system delivers the selected nitrous oxide and oxygen mixture in response to the patient’s inhalation. Patients remain conscious and spontaneously breathing during administration.
For gynecology practices, Nitronox Plus provides an additional patient-comfort option for in-office procedures, including hysteroscopy, endometrial biopsy, IUD insertion or removal, LEEP, and endometrial ablation.
In a 2026 randomized, placebo-controlled study (n=214) of women who underwent office hysteroscopy, patients who inhaled N2O reported reduced intraprocedural pain and improved satisfaction.1
Select nitrous oxide concentrations from 0% up to 70% (depending on which Nitronox Plus system you choose) to help tailor delivery to the patient, procedure, and level of support needed.
Nitrous oxide takes effect quickly and typically wears off within minutes after administration ends, supporting efficient in-office workflows.
Built-in safety features, demand-flow delivery, and the ability to switch to 100% oxygen when needed all help support confidence use in the office setting.
The use of nitrous oxide may result in occupational exposure. For information on nitrous oxide exposure in occupational settings, including guidelines, refer to recommendations from the National Institute for Occupational Safety and Health (NIOSH), the American Conference of Governmental Industrial Hygienists (ACGIH), and the Occupational Safety and Health Administration (OSHA).
