The impact of arterial catheter-to-vessel ratio on distal arterial flow and measured arterial pressures in a pulsatile arterial vessel phantom
Higher CVR in an in vitro model is associated with reduced distal flow and elevated systolic blood pressure in a phantom model. A CVR <0.4 (40%) appears to minimize flow and pressure changes. Appropriate selection of arterial catheter diameter for patient care may reduce risk of arterial catheter injuries and improve accuracy of clinical data.
