Abstract:
1. A fluid warming system to minimize heat loss through IV tubing to a patient, comprising: a) determining a temperature drop across a heat exchange body of an IV fluid warming device; b) determining a temperature drop of the IV tubing to the environment, the IV tubing extending from the IV fluid warming device to a patient; c) determining if the temperature drop along the IV tubing is greater than a determined temperature limit; d) determining if the total temperature drop along the IV tubing and across the heat exchange body is greater than a determined drop limit; e) if the determined values from step c) and step d) are greater than their respective limits, determining the actual fluid temperature as a fluid output temperature minus the drop limit; f) if either of the determined values from step c) and step d) are not greater than their respective limits, determining the actual fluid temperature as a fluid output temperature minus the heat exchanger temperature drop; and g) adjusting power to the heat exchanger to achieve the desired output temperature.
