Exploitation of a new noninvasive animal's blood pressure measuring apparatus and its function characterization / 中国应用生理学杂志

ABSTRACT

<p><b>AIM</b>To produce a new, noninvasive, animal's blood pressure measuring apparatus.</p><p><b>METHODS</b>By applying the principle similar with the measurement of human blood pressure, we developed a software which knowledge property owned by this research group and solved the problems of exactly demarcating the measuring spot of diastolic pressure. The blood pressure of rabbits was measured by the novel noninvasive animal's blood pressure measuring apparatus and the classic surgical catheterizing method simultaneously.</p><p><b>RESULTS</b>The novel noninvasive animal's blood pressure measuring apparatus was successfully set up. The measured blood pressures by this apparatus are very similar (r > 0.9) with the values obtained from the classic, surgical catheterizing method, no matter the blood pressures are normal, high or low.</p><p><b>CONCLUSION</b>Our new apparatus can be a reliable method for noninvasive measurement of the blood pressure of rabbits and rats.</p>
