![]() ![]() ![]() Radioradial and radiofemoral delay are not normal conditions. Normal situation radial and femoral pulsations are felt equally and synchronously.the inequality between two radial pulses is known as radio radial delay. Normal situation radial and femoral pulsations are felt equally and synchronously. A delay between the upstroke of the right radial pulse and a femoral pulse who presence indicates coarctation of the aorta. ![]() Causes of radio radial and radio femoral delay palpate the radial and femoral pulses (on the left or right) at the same time.Pathophysiology of ventricular septal defect (VSD) from 3.bp. How to elicit Hypokinetic (low volume), aortic stenosis, congestive heart failure, . ![]() So, one should always measure the systolic BP by palpatory method before confirming it by the auscultatory method.The radial and femoral pulses are palpated simultaneously. Now, while estimating the BP of such an individual, if someone does not take the precaution of having an idea of the systolic BP by measuring it by the palpatory method and thus raises the cuff pressure to a value within the auscultatory gap, say, 160 mmHg and then gradually lowers it, the first sound will occur at 140 mmHg, which will falsely be assumed as the systolic BP. The sound reappears at 140 mmHg and continues upto 100 mmHg which is the diastolic BP. Thus, if the cuff pressure is raised to, say, 200 mmHg and lowered slowly, the first sound appears at 190 mmHg but disappears at 170 mmHg. As for example, let us suppose that someone has a BP of 190/100 mmHg and in this person, no auscultatory sound is heard in between 170 and 140 mmHg. Sometimes, in some hypertensive individuals, the Korotkoff's sounds are inaudible in a certain pressure range and this may lead to error in determining BP. ![]()
