No. Air diffusing into water is quite a slow process which is primarily dependent on surface area. When you’re breathing out from scuba gear, the bubbles will generally be fairly large and as compact as possible because of the pressure of the water. This really small surface area will limit the ability of the gas to diffuse into the water.
Most dissolved oxygen in water will come from agitation. Dividing the water into millions of smaller droplets will give it infinitely more surface area for oxygen to diffuse into and greatly enhance the speed of the process. When water is agitated, these smaller particles are being created all the time and will restore dissolved oxygen levels quicker.
