At least 37.5 liters (9.9 U.S. gal) of seawater per minute would have to be passed through the system, but this system would not work in anoxic water. Seawater in tropical regions with abundant plant life contains 6–8 mg (0.093–0.123 gr) of oxygen per liter of water. [4] These calculations are based on the dissolved oxygen content of water.
Swift water rescue (also called "white water rescue") is a subset of technical rescue dealing in white water river conditions. Due to the added pressure of moving water, swift water rescue involves the use of specially trained personnel, ropes and mechanical advantage systems that are often much more robust than those used in standard rope rescue .

They typically use low power heating elements, about 1 kW to 1.5 kW, and can provide hot water long enough for hand washing, or, if plumbed into an existing hot water line, until hot water arrives from a remote high capacity water heater. They may be used when retrofitting a building with hot water plumbing is too costly or impractical.
