Evaluation of a simple device for regulating intravenous infusions
- 61 Downloads
Dial-A-Flo, and 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 infusions 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.
