Designed for use in the pre-hospital (ambulance) and in-hospital use (ER, Labor and Delivery etc.), the O-Two Equinox® Relieve is intended to provide a 50/50% mixture of nitrous oxide and oxygen, on demand, to a conscious, spontaneously breathing, patient for the relief of pain due to trauma or other conditions where inhalation analgesia is clinically specified. The system has no operator or patient adjustable controls eliminating the risk of delivering a hypoxic mixture. It only requires the attachment to pressure regulated medical gas oxygen and nitrous oxide cylinders and the patient circuit with mouth piece and scavenging hose to be ready for use.
The O-Two Equinox® Relieve consists of a dual gas (Oxygen and Nitrous Oxide) control module mixing system that maintains the output gas mixture at a constant 50/50 mix. Each of the two inputs have gas specific built-in alarm systems will generate both visual and audible alarms should either the nitrous oxide or oxygen input fall below 40 PSI, and the device will be automatically shut off should either the nitrous oxide or oxygen input fall below 35 PSI.
The O-Two Equinox® Relieve is also equipped with a secondary “fail safe” circuit that will activate an alarm and shut off the device should internal malfunction occur in the mixer or any internal hoses rupture or kink.
O-Two Equinox® Relieve N2O/O2 Analgesic Gas Mixing and Delivery System has only one control for turning ON or OFF the device. When it is turned ON, the output of the N2O/O2 gas mixture will only be activated by an inspiratory effort by the patient. The internal demand valve delivers high flow rates with low triggering pressures, reducing the amount of effort required by the patient to maintain the demanded flow. during use, the scavenging hose on the circuit assists in scavenging the patient’s exhaled air away from the patient environment.
Virtually maintenance free, the durable O-Two Equinox® Relieve N2O/O2 Analgesic Gas Mixing and Delivery System is a simple, safe and efficient way of delivering pain relief during trauma, childbirth or other painful procedures.
The optional Oxygen Enrichment feature allows the rescuer flush the system by depressing the manual button.
