Both lungs are covered with miliary shadows

X-rays of the chest of patients with nitrogen oxide poisoning can be seen with miliary shadows on both lungs. Nitrogen oxides include various compounds such as nitrous oxide (N2O), nitric oxide (N0), nitrogen dioxide (NO2), dinitrogen trioxide (N203), dinitrogen tetroxide (N204), and Dinitrogen pentoxide (N205) and so on. Except for nitrogen dioxide, other nitrogen oxides are extremely unstable. When exposed to light, humidity, or heat, they become nitrogen dioxide and nitric oxide, and nitrogen oxide becomes nitrogen dioxide. Therefore, in the occupational environment, several gas mixtures are often called nitrous oxide (gas), which are mainly nitric oxide and nitrogen dioxide, and mainly nitrogen dioxide.
