ENTONOX ^®-

ENTONOX^® is a patented pre-mixed pain-relieving gas of 50:50 nitrous oxide (N2O) and oxygen (O2). The gas is contained in a blue with a white and blue shoulder cylinder and delivered to the patients via inhalation by using a pressure regulator and demand valve.

ENTONOX^® is both highly effective and controllable in its effects:

Rapid onset and rapid recovery

Does not accumulate to any great extent within the body

Free from after-effects of the risk of overdose

Compatible with all other analgesic or therapeutic drugs

Effects are predictable, controllable and reliable

For ENTONOX^® we offer cylinders in the following sizes:

ENTONOX^®	5L water capacity	10L water capacity	47L water capacity
Gas capacity in CUM	1,620	3,240	16,200
Valve Operation	Pin index	Pin index	Pin index
Cylinder Pressure full (bar)	137	137	137

USES

A fast-acting analgesic ; relieve short-term pain conditions of mild to moderate intensity when rapid analgesic onset and offset effects are wanted; such as:

Normal labour

Acute trauma

Dental procedure

Painful procedure, eg: wound and burn dressing, wound debridement and suturing

Heliox-

Heliox is a gas mixture (79% helium and 21% oxygen) which is commonly used in deep diving, and also for clinical purposes, particularly in the critical care setting. Due to its low density Heliox breathing reduces air flow resistance within the bronchial tree in patients with obstructive lung disease, and has beneficial effects in severe asthma attacks. Heliox may also reduce the work of breathing and improve pulmonary gas exchange efficiency. Lower density of Heliox compared with the air or oxygen regardless of the concentration of helium in the mixture; improves air flow through constricted ways by transforming turbulent flow into laminar flow. Benefits are seen quickly, usually within an hour of initiation of treatment.

Specification:-

Heliox is supplied in the following specification under the Eur. Phar.:

Oxygen Ph. Eur 21% +/- 0.5%

Helium Ph. Eur 79% +/- 0.5%

Medical Air-

Medical Air is an important gas mixture used widely in all critical care areas to reduce human respiratory issues (pulmonary nebulization) or to treat hypoxia during mechanical ventilation or surgical procedures.

Dry grade is used to drive surgical air tools. It is also used to replace contaminated atmospheric air and as a carrier gas for volatile anesthetic agents. .

Nitrogen-

Nitrogen is produced in large quantities at air separation plants which liquefy and subsequently distill air into nitrogen, oxygen and argon. If very high purity nitrogen is required the nitrogen produced may need to go through a secondary purification process. The lower range of Nitrogen purities can also be produced with membrane techniques, and medium to high purities with pressure swing adsorption (PSA) techniques.

Nitrogen is used for inerting finished medicinal products sensitive to degradation by Oxygen. Compressed Nitrogen is a preferred source for driving of surgical tools.

Cryogenic liquid nitrogen has a boiling point of -196° C

Liquefied nitrogen is primarily used in the healthcare for:

As a cryogen for many applications where very low temperatures or rapid temperature reduction is required.

As an inert gas for the storage of medicinal products that are susceptible to oxidation in the presence of air.

As a purging and inerting gas by the pharmaceutical industry in the manufacture of medicinal products.

In cryopreservation of medical or research samples such as blood, stem cells and plasma.

As a component in many gas medical mixtures such as lung function test gases.

In routine equipment maintenance of the cooling magnets in MRI’s and NMR’s
