  1. IQR Inter-Quartile Range. Median infusion flow rates (p = 0.83) and interquartile ranges (p = 0.27) did not differ across syringe infusion pump devices. Median infusion flow rates (p = 0.15) and interquartile ranges (p = 0.71) did not differ depending on altitude. Median infusion flow rates (p for interaction =0.32) and interquartile ranges (p for interaction =0.66) for syringe infusion pumps did not vary significantly with altitude
