1. The possible disorder for Delilah is decompression sickness because she went scuba diving and now she is suffering from fatigue, numbness, dizziness and also a rash on her body.2. Decompression illness affects people who frequently change altitude, such as aviators, astronauts and divers. Nitrogen makes up 70% of the air around us, but at lower levels the air pressure is higher, so our body tissues absorb a greater amount of hydrogen at these levels. During the ascent, the pressure decreases and the nitrogen is expelled from our body, but if the ascent occurs too quickly for the hydrogen to be exhaled, bubbles form (like opening a fast soda) which can attach to the blood and tissues. The main factor affecting it is the reduction in ambient pressure, for example during rapid ascents or deep/long dives. Age is closely related to this, as older people tend to have a higher risk of disease as they tend to have a less efficient circulatory and respiratory system. Another risk factor is the amount of body fat a person has, as body fat tends to absorb nitrogen e....
