Indications for Use
The SEDARA™ Gas Mixer System is indicated for mixing and delivering Nitrous Oxide (N2O) and Oxygen (02), in a ratio of 1:1, at a fixed concentration of 50% / 50% (V/V), to spontaneously breathing patients of at least 15 kg body weight and four years of age, who have been examined by the attending physician prior to SEDARA™ System use and are under the continuous supervision of a healthcare professional in a clinical facility, such as a hospital, a free-standing ambulatory surgical center, or an outpatient clinic.
Device Story
SEDARA™ Gas Mixer System blends USP N2O and O2 to fixed 50%/50% (V/V) concentration; delivers gas on-demand to spontaneously breathing patients via internal demand valve and breathing circuit with hand-held face mask. System includes SEDARA™ Scavenger to remove exhaled gases via hospital waste disposal. Operated by healthcare professionals in clinical settings. Security Key required for activation and N2O cylinder access; cart stores incremental cylinders. Safety features include visual/audible alarms for gas flow absence, cylinder depletion, or technical failure. Device provides controlled analgesic gas delivery; benefits patient through precise, demand-based dosing and integrated waste scavenging.
Clinical Evidence
No clinical data provided; substantial equivalence based on technological characteristics and performance comparisons to predicate devices.
Technological Characteristics
Purely pneumatic, portable gas mixer. Materials include N2O/O2 cylinders, demand valve, breathing circuit, and face mask. Connectivity: None (standalone). Energy source: Pneumatic (gas pressure). Safety: Security Key lock, visual/audible alarms for flow/pressure/failure. Scavenging: Integrated waste gas removal system.
Indications for Use
Indicated for spontaneously breathing patients ≥15 kg and ≥4 years old requiring 50%/50% N2O/O2 gas mixture. Must be used under continuous supervision of a healthcare professional in clinical facilities (hospitals, ambulatory surgical centers, outpatient clinics) following physician examination.
Regulatory Classification
Identification
A breathing gas mixer is a device intended for use in conjunction with a respiratory support apparatus to control the mixing of gases that are to be breathed by a patient.

# Intended Use & Indication for Use:
The SEDARA™ Gas Mixer System is indicated for mixing and delivering Nitrous Oxide (NJO) and Oxygen (02), in a ratio of 1:1, at a fixed concentration of 50% / 50% (V/V), to spontaneously breathing patients of at least 15 kg body weight and four years of age, who have been examined by the attending physician prior to SEDARA™ System use and are under the continuous supervision of a healthcare professional in a clinical facility, such as a hospital, a free-standing ambulatory surgical center, or an outpatient clinic.
# Device Description
USP N₂O and 0₂gases are blended to the 50%/50% concentration (V/V) and delivered upon demand to spontaneously breathing patients through a demand valve internal to the SEDARA™ Gas Mixer. Patient inspiration draws the gas mixture via a breathing circuit with a hand-held strapless face mask.

SEDARA™ Gas Mixer System
f 315
The Oxygen is supplied by the user either from a standard gas cylinder or from an 02 wall outlet.
The Nitrous Oxide is supplied from a small cylinder equipped with a tamper-resistant valve.
The SEDARA™ Gas Mixer can be operated only with the use of a Security Key. The Security Key allows access and activation of the Gas Mixer, secures the N₂O Cylinder in use, and provides safekeeping of incremental N₂O Cylinders in the accompanying Transport Cart storage drawers, to guard against abuse and theft of the gas. The SEDARA™ Gas Mixer is provided with multiple levels of safety to ensure proper dosing. Visual and audible alarms signal the absence of adequate gas flow, the emptying of a gas cylinder, or technical failure of the mixer.
The gas exhaled by the patient into the face mask is channeled through the exhalation limb of the breathing circuit to the SEDARA™ Scavenger and removed via the hospital's waste gas disposal system.
# Intended Patient Population:
The SEDARA™ Gas Mixer System is intended for delivery of the gas mixture to spontaneously breathing patients of at least 15 kg body weight and four years of age, who have been examined by the attending physician prior to SEDARA™ System use and are under the continuous supervision of a healthcare professional.
# Substantial Equivalence:
SEDARA™ Gas Mixer is substantially equivalent to Nitronox K883833 gas mixer.
SEDARA™ Scavenger is substantially equivalent to the Passive Waste Scavenger K080039.
In comparison to the predicate device (Nitronox; K883833), the proposed gas mixer system has the same intended use and indications for use, uses a disposable face mask, is purely pneumatic and portable, connects to a small Nitrous Oxide Cylinder, mixes Nitrous Oxide and Oxygen to a 50%/50% (V/V) mixture with the same accuracy, and uses a demand valve for gas delivery. It includes a waste gas scavenger fully equivalent to the predicate scavenger (Passive Waste Scavenger; K080039).
The technical characteristics of the SEDARA™ Gas Mixer System do not introduce new questions regarding safety and effectiveness.
