Temperature Monitoring
A total of five ProMed recoveries (38.5%) were retrospectively identified to have temperature excursions outside the allowable 1 to 6 °C range. The median duration of temperature deviation was 60 min with a range of 6 to 198 min. 80% of the temperature excursions were noted immediately after cooler preparation and represent inadequate temperature conditioning of cooler components. In such cases, the temperature trend subsequently entered and remained in the allowable 1 to 6 °C range. Therefore, these deviations are favored not to represent a temperature change of the pRBC product. The median high-temperature excursion of all samples was 6.3 °C, while the median low-temperature deviation was 0.1 °C.
