40% If a self-inflating bag is connected to a 100% oxygen source, oxygen enters the bag through tubing connected between an O source and the O inlet port on the bag. However, each time you squeeze it, air (O concentration 21%) is drawn into the bag through the air inlet. The air is dilutes the concentration of O in the bag. -NRP Textbook AHA and AAP, 6th Edition. pg. 118-119

If you held your breath, the concentration of oxygen in your lungs would decrease. The concentration of carbon dioxide would increase in your lungs.
The concentration of oxygen in waters decreases.

A nonrebreather mask (NRB) should have an oxygen flow rate of at least 10 liters per minute in order to deliver the maximum oxygen concentration.

Self inflating rafts come with their own compressed air; that's why they are self inflating. If it was not self inflating you would have to pump air into it to inflate it. In either case, rafts can be inflated by any form of gas, it does not have to be oxygen.

You want the maximum amount of oxygen, which is 100%, and the ambu bag, with the oxygen attached, will deliver that.
The concentration of oxygen in water is 88,88 %.
The concentration of oxygen decrease.
The concentration of oxygen decrease.
For a healthy environment, the temperature of a body of water needs to be inversely proportional to the concentration of dissolved oxygen in it. The higher the oxygen level, the temperature needs to be lower to promote fish growth.
