What is the role of the air in the ICU?

Many people think that air is used for breathing, and it is the same in the icu ward. Not exactly. The air in the icu ward has taken on much more tasks than we thought.

First of all, the most important point is that the air in icu ward must be clean. The patients who live in it are very weak and have poor immunity. A little bacteria or dust may make their situation worse. Therefore, the air in the icu ward has to be filtered layer by layer to keep all the invisible dirty things out. The inside of the ward will also maintain a slightly higher air pressure than the outside, so that the outside air is not easy to drill inside, and the clean air inside is not easy to run out. This reason is like setting up a transparent protective cover for the ward.

Secondly, the air in the icu ward has another key purpose, which is to power various medical equipment. There are ventilators, oxygen-making equipment, and many other instruments that rely on compressed air to work. These devices require a steady stream of clean compressed air to function properly and help keep patients alive. If the air supplied to these equipment is mixed with oil or other impurities, not only the equipment is prone to problems, but the discharged gas directly contacts the patient's respiratory tract, which is very dangerous.

Therefore, the icu ward has a particularly high demand for air, which should be clean and should not contain oil. When the traditional air compressor is working, the inside will use oil to lubricate the parts, and more or less there will be some oil and gas mixed into the discharged air. Although most of them can be removed after filtering, it always makes people feel uneasy.

At this time, the water lubricated air compressor comes in handy. The working mode of water lubricated air compressor is not the same as that of ordinary air compressor. Ordinary air compressors rely on oil to reduce friction between parts, while water-lubricated air compressors use water instead of oil, allowing water to flow inside the machine, which also reduces friction and takes away heat. Because water is used instead of oil, the compressed air discharged is completely free of oil and naturally clean.

The water lubricated air compressor can play a great role in the air supply system of the icu ward. The compressed air it outputs is very clean, and after subsequent filtering and processing, it can meet the strict requirements of the icu ward on air quality. Moreover, water is easier to obtain than oil, and there is no problem that oil deterioration needs to be replaced frequently. Later maintenance is relatively worry-free. for icu wards that require round-the-clock uninterrupted air supply, this stable and reliable way of air supply is very suitable.

In addition, the air in the icu ward also needs to control humidity. If it is too dry, the patient's respiratory tract will be uncomfortable, and if it is too wet, it will easily breed bacteria. The air treatment system will adjust the humidity to a range that makes the patient feel comfortable and at the same time is not conducive to the growth of bacteria. The premise of all this is to have a stable and reliable compressed air supply system behind the support.

In general, the air in the icu ward is not only used for breathing, it also powers various life-saving equipment and acts as a barrier to isolate external pollution. The water-lubricated air compressor is becoming an increasingly important air supply option in this scenario with extremely high air quality requirements because the output air is oil-free and cleaner.
