Generally speaking, when inhaling oxygen, the oxygen passes through the fossilized bottle to the oxygen absorbing tube, and then is sucked into the lungs; the use of the fossilized bottle is to increase the water vapor within the pure oxygen, to avoid drying the mucous membrane within the trachea when dry oxygen passes through the respiratory tract, if the fossilized bottle is overfull of water or the flow rate of oxygen is too large, the oxygen is prone to bring the water directly into the flowmeter when it passes through the bottle, and then flows into the oxygen absorbing tube. If the water in the bottle is too full or the oxygen flow rate is too large, the oxygen will easily bring the water directly to the flowmeter when it passes through the bottle and then flow into the oxygen absorbing tube.
Please teach the question mentioned in the "fossil bottle" is what, general oxygen, hyperbaric oxygen cabin oxygen, as well as respiratory machines, anesthesia machines and other equipment involved in oxygen absorption have not heard of the circuit pipeline in this thing.
