The maximum oxygen concentration you can deliver with a self-inflating bag is typically 100%. The bag is connected to an oxygen source, such as an oxygen tank or wall outlet, allowing you to adjust the oxygen flow rate to achieve the desired concentration.
A self-inflating mask does not deliver oxygen on its own. It requires a separate oxygen source such as an oxygen tank or concentrator to deliver oxygen to the user. The mask acts as a medium to deliver the oxygen to the person wearing it.
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
The oxygen delivery device that provides the highest concentration of oxygen is the non-rebreather mask, which can deliver oxygen concentrations of up to 90-95%. This mask is used in situations where a high concentration of oxygen is needed, such as during severe respiratory distress.
The maximum volume of oxygen that the human body can use and process in one minute is called the VO2 max. It is a measure of a person's aerobic fitness and represents the maximum capacity of the cardiovascular and respiratory systems to deliver and utilize oxygen during exercise. VO2 max is often used as an indicator of an individual's cardiorespiratory endurance.
Pure oxygen can be obtained through processes such as fractional distillation of liquid air or electrolysis of water. These methods extract oxygen from air or water and purify it to remove impurities, resulting in a high concentration of pure oxygen. Additionally, specialized oxygen concentrator devices can also extract and deliver pure oxygen for medical or industrial use.
The maximum percentage of oxygen that can be delivered with a self-inflating mask and an oxygen blender without an oxygen reservoir is typically around 50-60%. This is because the blender mixes ambient air with oxygen in a fixed ratio determined by the blender settings.

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.

Combining capacity for oxygen refers to the maximum amount of oxygen that can be bound to hemoglobin in the blood. It is influenced by factors such as the concentration of hemoglobin in the blood and the oxygen saturation level. This measurement is important in assessing the oxygen-carrying capacity of the blood.
