ASUS VW193S
As compared to the above model the dynamic contrast of VW193S was implemented earlier therefore the stated value seems moderate. However in practice the static contrast of both monitors may well prove to be identical but we can check this a bit later. Formally the product specifications state lesser horizontal viewing angle but I failed to notice this difference in practice. Probably the human eye is that perfect…

To make it easier for you to navigate through the model lines of this manufacturer please note that ‘S’ letter in the end of VW model line means this monitor belongs to inexpensive devices without digital input. This feature is also absent in models with D letter at the end but in addition they lack dynamic contrast mode. While models with ‘Ñ’ and ‘Ò’ letters have both analogue and digital inputs. By the way let’s get back to our test object. Drivers for ASUS VW193S
This model is available both with a light strip and without it. If the variant with the light strip resembles the above mentioned VW192C slightly differing by the base, a totally black model looks somewhat austere and will be appreciated by those who want to get a ‘pitch black’ PC.

Oxygen can be used both as a remedy and as a means of prevention and stimulation of different life support processes. As elderly people have clear symptoms in case of oxygen shortage in the body, we will observe the influence of the use of this gas by them.

The elderly people have practically the same lungs volume, but as they become less active physically, the depth of their breath and the volume of the air that comes into the lungs decrease considerably. As a result, much less oxygen comes into the body, which gradually leads to hypoxia of different organs. The bran and the cardiovascular system are especially affected by a shortage of oxygen.

Oxygen therapy administered with the help of special oxygen equipment beneficially influences the patient’s mood and his appearance – he becomes more confident, sociable and lively.

After the body is saturated with the necessary amount of oxygen, headaches that are a problem for many elderly people become less frequent or disappear altogether. Sometimes they reduce the amount of medicine taken to stop headaches, and there are also cases when it is no longer necessary due to great effect of oxygen therapy.

If the brain is saturated with the necessary amount of oxygen before sleep, the quality of sleep and its depth will improve considerably and the person’s working capacity will increase substantially. That’s why doctors recommend the elderly people a walk in the fresh air before sleep. Thus if the sleep at night becomes deeper, it will make the person more active during the day, improve his mood, increase working capacity and reduce the possibility of conflict situations development.
