A true experimental research design was selected to determine the effect of insulating blood warmer output tubing on the temperature of packed red blood cells at the point of patient entry at low flow rates. Utilizing a surgical suite, every attempt was made to replicate a true surgical setting. Flow control pumps were used to regulate flow rates of 300, 600, and 900 milliliters per hour mlhr through Fenwall Laboratories blood warming coils. Room temperature was maintained at 20.0 or - 0.5 C. Insulated and non-insulated blood warmer output tubing was compared. Results of the study showed that insulation significantly decreased the amount of heat loss that occurs in non-insulated output tubing.
