Abstract
A heater for physiological solutions that is effective at low and high flow rates includes first and second heat exchangers that have different fluid heating characteristics. The first heat exchanger is capable of heating solutions at high flow rates, while the second heat exchanger is designed to heat the solutions at low flow rates. A warming fluid is circulated through the heat exchangers, and a manifold is provided to control the flow of the warming fluid that is directed to the two heat exchangers. The solution to be warmed is directed to both heat exchangers such that a warmed solution is provided irrespective of the flow rates.
