Let’s talk about hypertension. And I’ll write that

here, hypertension. And hypertension basically

means high blood pressure. And we actually categorize

it in different groups. So let’s use my blood pressure,

115 over 75 as an example. And I had drawn a

small figure for you where I had blood

pressure on this side and I had time on this side. And I said at my blood

pressure does something like that, where

the peak is 115. This is the systolic

blood pressure. And I said that the lowest point

is going to be, for me, 75. And that was my

diastolic blood pressure. And we know everyone has a

different blood pressure. So let’s organize blood

pressures into groups. Let’s say, let’s figure

out what group goes where. And so, to do that, I’m going

to draw a couple number lines. So let’s imagine that I

have, here in brown, I’ll do my systolic blood

pressure on this side. And I’ll do the diastolic

on the other side. I’ll do diastolic over here. And we’re going to actually

put them next to each other. And I’ll try to make about

the same size, like that. So let’s say this is

really high pressure. This would be like 200. And this is all in

millimeters of mercury. 200 millimeters of mercury. And at the very

bottom would be 0. So let’s make them

kind of the same. And that means that up

here would be about 100. And this would be about–

let’s say this is 120. This would be about

140, let’s say. Maybe this is 160. And this is 180. And I’m going to do

the same thing here. Let’s say this is about

100, except this time I’m going to go the other side. Let’s say this is about

80, and this is 60, 40, 20. Maybe I didn’t draw it as well,

but I think you get the idea. So this is my number line. And the reason I drew the

systolic numbers higher than the diastolics

is because we know that generally speaking–

or not generally speaking– always the systolic

pressure is going to be higher than the

diastolic pressure. So that’s why I

separated it out. But you can imagine

that these numbers go up and these go down. I’m just being lazy

not drawing it all out. So let’s say that

my pressure is 115. This in my systolic pressure. Now let’s do that one first. Where does that fit? Well, on this number line,

115 would be about right here. And actually anything

below 120 is actually kind of in the green zone. And this goes all

the way down, to 0. So let’s say my

systolic was 97, or 103. That would all be

in the green zone. And what I mean by

that is, I would say I do not have hypertension. I have no hypertension. So that’s kind of

a nice, safe, area to have your blood pressure

in, in terms of hypertension. Now for diastolic pressures, we

know that diastolic pressures are the low range

of a blood pressure. And so those numbers

are going to be lower. Here, anything below

80 is considered in that safe green zone. So below 80 is where

you want to be. And I want to be

very specific, I don’t mean to say that a blood

pressure of 5 would be good. What I mean is that you

don’t have hypertension. So you don’t have

high blood pressure. And that’s where it’s different

from having low blood pressure. So just for right now, the green

zone in terms of high blood pressure. Now, let’s say my

systolic blood pressure was a little bit higher. Let’s say it’s between 120

and 140, somewhere in here. Then I’m in the yellow zone. And that yellow zone means

that I don’t have hypertension, but I’m getting there. So I’m getting closer, and

this would be prehypertension. And on the other side,

on the diastolic side, we use 90 as a cut off. So I’ll write in 90. And anything between

80 and 90 would be kind of in that yellow zone. And that’s your

prehypertension zone. It’s prehypertension. So you’re still not there yet. Now in terms of high

blood pressures– again, you don’t want

high blood pressures– but in terms of getting

there, if you’re above 140, you have hypertension. So this zone in here,

140 to 160 in particular, is considered stage

one hypertension. And between 90 and 100 for

diastolics, that would be stage one. And now if you have

something above 160 for your systolic

blood pressure– so I’ll just say

above 160, and that means even higher than

200, so if let’s say you have 201– that

would be stage two. So you can see that

the higher you go, the higher your stage number. And the same is

true on this side. So let’s say you have a

really high diastolic blood pressure, well above 100. You’d have stage

two hypertension. All the way down there,

this is stage two. So I’m just going to do a

couple quick examples for you. So let’s say– I’ll do them

in yellow, different color– let’s say that you

have 145 as a systolic. And your diastolic

is, let’s say, 87. Well, 145 is right here, right? And 87– actually, let me

do it the same color just to be consistent. So 145 is right here. And 87 is in here. So your systolic pressure

is stage one hypertension, and your diastolic pressure

is in prehypertension. So when you’re in different

stages for the diastolic and the systolic what

you do, the rule, is that you go with

the higher stage. So in this case,

stage one is higher. So this person would

be considered stage one hypertension. Now we can do one more example,

just to make sure you get it. So let’s do a different color. Let’s say I’ll do

the next one in red. So you have, let’s say

126 over, let’s say 101. Well, this person, 126

is actually right here. And 101 is right above

the 100 mark, right there. So this person is

actually prehypertensive if you’re looking at just

their systolic value. But they’re actually in

stage two hypertension if you’re looking at

the diastolic value. So overall, they’re

going to be in stage two, because the rule, again, is that

you go with the higher stage. So that’s how you

figure out what stage of hypertension

someone’s in.
