Blood Pressure

Postby Edher » Mon Nov 14, 2005 3:52 am

Saludos,

I'm trying to understand how blood pressure is measured. Why is there two readings? The first one I get, but what does the second one tells us?

Thank You,
Edher

Measuring blood pressure by using an equipment named Sphygmomanometer. Sometimes we need a additional tool named stethescope to increase the validity of the data.

Two readings:
- the first is systole - when the heart contracts or the filling session
- the second is diastole - when the heart relaxes or the release session

actually electronic devices that you put around your wrist are available at the market to take your blood pressure(much smaller and easier to use). i have one. my father uses it because he had a heart attack a while ago

The diastolic pressure is the pressure of the blood when the ventricles contract and the auricles (atriums) fill with blood.

Systolic pressure is the pressure of the blood when the auricles contract and the ventricles fill.

Hi,
Does anyone know what's the difference between the 2 different types of methods to measure blood pressure such as palpation and auscultatory? I read in wikipedia that palpation tends to overestimate the values of the blood pressure but it did not explain why that is so. Someone enlighten me please.

Cheers,
Scinoob :oops:

Well, as it's written at Wikipedia, palpation's not that accurate. About why does it tend to be higher, I'm not too sure but we usually use auscultatory method because it has got two readings (i.e. [systolic/diastolic]). Whereas for palpation, it has only got one reading, which is pretty limited to certain diagnosis.

Did this helped out partially?
