RenaPulse tubing is made from a new material which transmits pulse waveforms with high fidelity. During pressure pulses, fluid flows into the catheter and depresses the diaphragm of a pressure transducer. However, the same pressure wave that reaches the transducer also causes the pressure catheter to bulge slightly. This bulging may allow a significant volume of fluid to flow in and out of the catheter with each pulse. Given the resistance of the catheter, this small flow can lead to pressure drop along the catheter and inaccurate pressure readings from the transducer.
RenaPulse is a stiffer tubing which allows high fidelity measurement of systolic and diastolic pres-sures. Because air bubbles in pressure catheters are very ‘soft’, they can completely distort the pulse wave. We make RenaPulse tubing transparent to help you locate and remove such bubbles. Small clots can block pressure catheters, and prevent pulse waves from reaching the transducer. Since RenaPulse has the superb blood compatibility of Micro-Renathane, the chance of clot formation is much reduced.
These features make RenaPulse the tubing of choice for high fidelity pressure measurements in small animals. RenaPulse is flexible enough for direct vessel insertion. It can be bonded to luer lock terminations and stopcocks. RenaPulse can also be used with standard compression adapters or needle stubs.
