Blood Pressure

Proper assessment of cardiac function and hemodynamic performance requires a measurement of pressure from within the heart and peripheral arteries. iWorx offers several solutions for measuring pressure including fluid‐filled pressure transducers, catheter-tipped micro pressure sensors and non‐invasive tail cuff pressure systems.LabScribe software with the Blood Pressure Module provides built‐in software routines to perform a number of arterial and ventricular pressure calculationsFluid-Filled Catheter SystemThe BP-100/102 blood pressure transducer is an economical and accurate device used to measure direct arterial or venous pressure in animals using the fluid-filled catheter technique. A precision laser-trimmed chip provides accurate and linear measurements over a broad range of pressures. Pressure changes in the vessel are transmitted within the fluid-filled tube to the pressure transducer and acquired for monitoring and further analysis. Tubing is available as small as 1 mm in outside diameter making this technique well-suited for measuring pressures in very small vessels. Blood pressure systems include the transducer, cable, data recorder and software.Bladder PressureThe BP-100/102 blood pressure transducer can also be used to measure bladder pressure.
