Oxygen is perhaps the most widely used medical gas, supporting resuscitation, inhalation therapy, life support for artificially ventilated patients, overcoming shock, and reducing incidences of surgical wound infection.

Oxygen also provides the basis for nearly all modern anesthetic techniques.

Medical Grade Pharmacodynamic properties

Pharmacotherapeutic group: medical gas
ATC code: V03AN01
The characteristics of medical oxygen are:
• odourless, colourless gas
• molecular weight 32.00
• boiling point -183.1ºC (at 1 bar)
• density 1.335 kg/m3 (at 15ºC).
Oxygen is present in the atmosphere at 21% and is essential for life.
The basal oxygen consumption in man is about 250 ml/min for a body surface of 1.8m². It is reduced by about
10% during anesthesia and natural sleep and by about 50% for a 10ºC fall in body temperature.
Alveolar air contains about 14% oxygen (105mm Hg) and arterial blood has an oxygen tension of
97mm Hg. The difference, known as the alveolar-arterial oxygen tension gradient, increases with age. The
difference may be as great as 30mm Hg in a healthy, elderly individual.
Oxygen in the blood is mostly combined with hemoglobin. 1.34ml per 9ml to give a maximum capacity of
20 ml per 100 ml of blood. A small amount, 0.3 ml, exists in solution in the same volume of blood.
The concept of oxygen availability first described by Richards in 1943 and later elaborated by Freeman and
Nunn has been used to quantify the amount available to the body.
It can be expressed as the product of cardiac output and the blood’s oxygen content.
Available oxygen is calculated by:
(cardiac output) x Hb concentration x 1.34 x (% saturation)
Substituting the normal values for available oxygen the amount is:
Available oxygen: ((5000ml) 15/100 x 1.34 x 95/100) = 950ml
The average healthy individual with a basal oxygen consumption has no more than four minutes supply of
oxygen in the blood.

Medical Oxygen Cylinder Therapeutic indications

Medical Oxygen is widely used in clinical practice to:
• provide a basis for most modern anaesthetic techniques, including pre and postoperative management.
• restore the tissue oxygen tension towards normal by improving oxygen availability in a wide range of
conditions such as:
‐ cyanosis of recent origin as a result of cardio-pulmonary disease
‐ surgical trauma, chest wounds and rib fracture
‐ shock, severe haemorrhage and coronary occlusion
‐ carbon monoxide poisoning
‐ hyperpyrexia
‐ major trauma, i.e. road traffic accidents and gunshot wounds
‐ in the management of sudden cardiac and respiratory arrest, whether drug-induced or traumatic
• aid in the resuscitation of the critically ill when circulation is impaired
• aid in neo-natal resuscitation
• treat acute-severe headache in adults diagnosed with cluster headache
