Oxygen is used as a medical treatment in both chronic and acute cases, and can be used in hospital, pre-hospital or entirely out of hospital, dependent on the needs of the patient and their medical professionals’ opinions. Oxygen is widely used in emergency medicine, both in hospital and by emergency medical services or those giving advanced first aid.
In the pre-hospital environment, high flow oxygen is definitively indicated for use in resuscitation, major trauma, anaphylaxis, major hemorrhage, shock, active convulsions and hypothermia.
Oxygen should never be given to a patient who is suffering from paraquat poisoning unless they are suffering from severe respiratory distress or respiratory arrest, as this can increase the toxicity.
Oxygen has vasoconstrictive effects on the circulatory system, reducing peripheral circulation and was once thought to potentially increase the effects of stroke. However, when additional oxygen is given to the patient, additional oxygen is dissolved in the plasma according to Henry’s Law. This allows a compensating change to occur and the dissolved oxygen in plasma supports embarrassed (oxygen-starved) neurons, reduces inflammation and post-stroke cerebral edema.
Highly concentrated sources of oxygen promote rapid combustion. Oxygen itself is not flammable, but the addition of concentrated oxygen to a fire greatly increases its intensity, and can aid the combustion of materials (such as metals) which are relatively inert under normal conditions. Fire and explosion hazards exist when concentrated oxidants and fuels are brought into close proximity; however, an ignition event, such as heat or a spark, is needed to trigger combustion
Demand valves or oxygen resuscitators deliver oxygen only when the patient inhales, or, in the case of an apnic (non-breathing) victim, the caregiver presses a button on the mask. These systems greatly conserve oxygen compared to steady-flow masks, which is useful in emergency situations when a limited supply of oxygen is available and there is a delay in transporting the patient to higher care.

A type (0.71m3), B type (1.43m3), D5 type (5m3) and D7 type (7m3) and the cylinder pressure is 150 kg/cm2
Medical Oxygen is used for patients requiring supplemental oxygen via a mask. In small medical centers with a low patient capacity, oxygen is usually supplied by multiple standard cylinders.
