Measuring blood pressure, impotence penis
Penile blood pressure measurement results are often not a constant, which causes both technical limitations, there are penile vascular response to environmental and emotional reasons. So, if the measured anomalous results, we must verify it possible to make repeated measurement index of abnormal penile arteries conclusion.
Arterial blood pressure measurement in the diagnosis of arterial insufficiency may be helpful, but this one test alone to exclude arterial insufficiency as a cause of impotence the time of diagnosis is not very reliable. Commonly used penile artery blood pressure index to represent the penis, penile artery index = penile arterial blood pressure / arm blood pressure.
Normal penile artery index close to 1.0, more than 0.8 shall be normal. When the penile arterial blood pressure than the systemic arterial blood down an average of 30 mmHg (4.0kPa), or penile artery index less than 0.6 as abnormal. Penile blood pressure measurement to determine the outcome of the principles of the following:
(1) at least one artery of the penis artery index of “0.6, will damage erectile function (very rare only one artery index” of 0.6, while the remaining three normal arteries), arteries of the penis the most meaningful readings .
(2) one or more root artery is between 0.6 ~ 0.8, indicating that the partial failure of vascular function.
(3) All arterial index more than 0.8, indicating that the penis and improve vascular function.
(4) All arterial index more than 0.8, indicating that the penis and improve vascular function. When the bilateral cavernosal artery systolic pressure difference of up to 30mmHg (4.0kPa), the show within the pudendal artery and its branches have clinical significance of damage.
However, the results of penile blood pressure measurement is often not constant, which causes both technical limitations, there are penile vascular response to environmental and emotional reasons. So, if the measured anomalous results, we must verify it possible to make repeated measurement index of abnormal penile arteries conclusion. And it does not clarify the blood flow in any case, but can not detect a state of erection of the penis artery function. Therefore, the diagnosis of this method remains to be further improved and improving.
