a simple oxygen mask used in a diving accident, for example, with reservoir bag and one-way inhalation valve for inhaling oxygen or the one-way exhalation valve prevents room air be breathe, I have a lot of work going on had, but I am satisfied with the result, I found the especially difficult for the second exhalation valve to make but I quickly found a solution for it.
