title: Air inlets for infusion bottles.
abstract: We assessed the resistance to air flow in four commonly used air inlets. The Avon A81 and Codan air inlets provide the least resistance to flow, followed by the Baxter CO413 and lastly the Braun air inlet. The presence of a valve confers an advantage when rapid infusion of fluid is attempted. The valve in the Codan air inlet performed best out of the inlets tested.
