0:00now in relationship to our two numbers
0:02systolic and diastolic the contraction
0:05and the relaxation of the heart what
0:08we're seeing there is the patient's
0:10blood pressure now with blood pressure
0:12the force uh this is forced blood that
0:15exerts on the inner walls of the blood
0:17vessels
0:19and there are factors that can cause it
0:21to be elevated or to be below our normal
0:25range
0:26normally what we see is the number is
0:28going to be highest in the arteries
0:31lowest in the veins as far as the
0:33pressure
0:34and this is the rise in the fall of the
0:36ventricles as they contract and relax
0:38that one cardiac cycle
0:41and again remember we have factors that
0:43can change uh can Elevate or lower one's
0:47blood pressure here's your systolic in
0:49your diastolic and systolic ventricles
0:52contract diastolic ventricles relax so
0:56again High number and systolic usually
0:59120 is where we'd like to see our
1:01patients in a normal range 120 over 80
1:0580 being our diastolic or our lower
1:07number where we'd like to see our
1:10patients in range so 120 over 80 would
1:12be typical if you have a patient that
1:15has high blood pressure you can also
1:17expect to see a higher pulse so factors
1:21that can affect blood pressure you have
1:23the cardiac output how fast and how
1:25strong the art beats we want to have a
1:28nice strong cardiac output but we don't
1:31want our heart to overwork so if it is
1:34enlarged if it does have blockage if it
1:37does have damage that blood volume still
1:40needs to make its way through and so
1:42what you're going to see is a higher
1:44level of cardiac output because the
1:47heart still has a job to do and it's not
1:50going to let anything get in its way but
1:53when we do obtain a patient's blood
1:55pressure we're definitely going to see
1:57those higher numbers two terms
1:59vasoconstriction and vasodilation has to
2:02do with what's called blood viscosity
2:04the thickness of the blood if one's
2:07blood is very thick that could also
2:09cause the heart to have to work harder
2:11to be able to do its job to get that
2:14blood through those valves
