Nitrous Oxide gases have been known to have sedative and
analgesic effects for well over two hundred years. In the medical
application, Entonox is a gas comprising of equal parts of Nitrous
Oxide and Oxygen, most commonly used during childbirth. The gas is
administered via the entonox circuit and inhaled by the patient
using either a face mask or a mouthpiece. An incorporated demand
valve is regulated by the patient's inhalation pattern allowing
gases to be controlled and not lost to the bient surroundings.

Lightweight
22mm Corrugated tube will retain it's shape and resist crushing.
Flow is still maintained even when twisted through 180°. The
shallow corrugations minimise flow resistance and turbulence.

Patient Choice
The entonox circuits are available for use with a mouthpiece or
mask providing patient choice.

Entonox T-Piece
The T-Piece incorporates 2 non-return valves to allow for
inspired gases to be delivered through the system and prevent
expired gases re-entering the circuit.

Patient Controlled during child
birth
Patients should inspire the Entonox gas as soon as a contraction
begins. The level of pain control that is built up in the blood
stream will reach maximum effectiveness between 45-50 seconds after
patient begins breathing. Using Entonox gas does not prevent
patients being given supplemental or alternative pain relief
drugs.
