Dial-A-Flo, an infusion control device, is assessed for accuracy, in vitro and in vivo. The unit did not permit accurate control and particularly so at lower flow rates. The normal spontaneous variations in venous pressure that occur around an infusion cannula tip, further increase the error of gravity-fed infusions. Dial-A-Flo has no advantage over a standard administration set alone, and should not be used for controlled administration of cardiac drugs.
“Dial - A - Flo”输液控制装置在体外和体内进行了准确性评估。该装置无法实现精确控制，在较低流速下尤其如此。输液套管尖端周围静脉压力的正常自发变化，进一步增加了重力输液的误差。“Dial - A - Flo”相对于单独的标准给药装置没有优势，不应将其用于心脏药物的控制性给药。
