Oxygen production sufficient,Patient needs oxygen

Oxygen: The second wave of the epidemic has not only been fatal in India but also a large number of flaws and shortcomings in health services. The biggest drawback is that of liquid medical oxygen (LMO). But why is this happening, why are things deteriorating? To understand this, the system of production liquid oxygen in the country and passing it on to the patient has to be understood. The lives of thousands of people could save by removing them in time, but the government delayed taking steps.

Oxygen production sufficient,Patient needs oxygen

According to government data, till recently India was producing 7,127 metric tonnes of liquid oxygen annually. This was enough for both medical and industrial use in normal times. The epidemic increased medical use demand by more than four times.

For example, India needed 750 to 800 metric tons of oxygen annually before 2019. On April 12, the demand rose to 3,842 MT after the second wave arrived. 10 days later, on 22 April, this requirement had gone up to 6,785 metrics.

 The patient needs oxygen


There is 21 percent oxygen in the Earth’s atmosphere. Our lungs filter oxygen from the air that enters the air through the breath. But the capacity of the oxygen to absorb in the lungs of a patient affected by Kovid 19 starts decreasing, so he needs more oxygen content instead of 21 percent of the air. Not only this, liquid oxygen supply is useful.

How oxygen is made?


There is a lot of oxygen in our atmosphere, but tell you where the oxygen comes from inside the cylinder. Here let us tell you that the gas is made of oxygen through the cryogenic distillation process. In this process, the air filters, in this way the dust and soil are separate from it. After this, in many states, the air pressurizes or compress.

After this, the compressed air is treated with molecular sieve adsorption. This is done so that water particles, carbon dioxide, and hydrocarbons can be separated from it. At the same time, when this process is completed, then the compressed air goes into the distillation column.

Here it is first cool (all through a plate-fin heat exchanger and expansion turbine process) and then heated to 185 ° C, which is then distilled.

Here, tell you that distill is a process in which water is boil and its steam is condensed and deposited. This process is done several times at different stages. In this, gases like oxygen, nitrogen, and argon are separated. It is only after this process that liquid oxygen and gas oxygen are mixed.
