0.97 -> - [Josh] Hi, I'm Josh
Farquharson and welcome
3.3 -> to Blood Pressure: Audio-Visual
Coordination Skills.
7.61 -> There are several steps involved
9.11 -> in taking a blood pressure measurement,
10.86 -> and each step must be
completed with accuracy.
14.44 -> This is especially true when
viewing the blood pressure dial
17.43 -> and listening with the stethoscope.
20.26 -> You must be able to effectively coordinate
22.39 -> what you're hearing
with what you're seeing.
26.18 -> Just imagine if you recorded
a patient's blood pressure
28.78 -> as normal when in actuality,
31.02 -> their pressure was extremely high,
32.86 -> and they were at risk for having a stroke.
36.16 -> Your inaccuracy can have dire consequences
38.77 -> on the patient's overall health.
41.76 -> This lesson will help you achieve accuracy
43.87 -> when taking blood pressure measurements.
47.33 -> By the end of this lesson,
48.53 -> you will identify and interpret
the graduation markings
52.3 -> on an aneroid sphygmomanometer dial
55.42 -> and determine the systolic
and diastolic blood pressure
58.73 -> by reading the dial and listening
to the Korotkoff sounds.
63.48 -> If you ever had your blood pressure taken,
65.71 -> you likely noticed that
the results were stated
68.01 -> as one number over the other number,
70.55 -> such as 120 over 80.
73.8 -> The number on top, in this case, 120,
76.75 -> represents systolic pressure,
79.2 -> and the bottom number, in this case, 80,
82.1 -> represents the diastolic pressure.
85.08 -> Let's take a close look at the dial
86.81 -> used for determining such a measurement.
90.4 -> This is the aneroid sphygmomanometer dial,
93.58 -> also known as the blood pressure dial.
96.92 -> The dial has the letters mmHg
99.75 -> because blood pressure is measured
101.45 -> in millimeters of mercury.
104.1 -> Also, on the dial,
105.04 -> you'll notice that there
are lines in various sizes.
108.6 -> The largest lines represent values of 20.
112.33 -> This is 20.
113.57 -> This is 40, 60, and so on.
118.67 -> The medium lines represent values of 10.
122.15 -> This is 30, 50, 70, and so on.
127.7 -> And the smallest lines
represent values of two.
131.44 -> So this line represents
22, 24, 26, 28, and so on.
140.19 -> Now let's use the needle
141.6 -> to determine the number
displayed on the dial.
144.9 -> Concentrate on the tip of the needle
147.36 -> and the line that it's pointing to.
150.18 -> How much does this line represent?
153.71 -> If you stated 68, you are correct.
157.94 -> So how much does this line represent?
162.75 -> If you stated 112, you are correct.
167.16 -> And how much does this line represent?
172.24 -> If you stated 294, you
are absolutely correct.
175.96 -> Great job.
177.45 -> Now that you're comfortable
178.6 -> with reading the blood pressure dial,
180.88 -> let's apply audio-visual
coordination skills.
184.67 -> And for this, please
increase your volume level
187.39 -> and have a pen and paper on hand.
191.19 -> There are two main areas
that you need to focus
193.64 -> on when determining a
blood pressure reading.
196.69 -> One, the position of
the needle on the dial,
200.82 -> and two, the Korotkoff sounds.
204.16 -> We'll refer to the Korotkoff sounds
206.24 -> as thumping sounds for the
duration of this video.
210.93 -> When you arrive at the
point of the procedure
213.09 -> when you slowly deflate the
cuff to hear the sounds,
216.48 -> you will notice the needle move
218.02 -> in a counterclockwise direction.
221.01 -> It is at this point that you
need to listen very closely
224.16 -> for the thumping sounds.
229.03 -> Upon hearing the first thump,
231.1 -> note the needle's position on the dial
233.01 -> and record the number.
235.13 -> That's the systolic pressure.
237.86 -> As the cuff deflates and the
needle continues to move,
241.48 -> you will continue to
hear the thumping sounds.
244.72 -> Listen closely for the last thump.
248.15 -> Upon hearing the last thump,
250.07 -> note the needle's position on the dial.
253.13 -> That's the diastolic pressure.
256.58 -> Let's practice applying these two steps.
260.04 -> Please note that your answer
may be slightly different
262.72 -> from what's displayed, but that's okay.
265.48 -> As long as your answer
266.64 -> is within four millimeters of mercury,
269.13 -> your answers are still
considered accurate.
272.3 -> For example, if the displayed
answer is 120 over 80,
276.81 -> but your answer falls
somewhere in the range
279.11 -> of 118 over 78 through 122 over 82,
284.39 -> your answer is still considered accurate.
287.69 -> Of course, matching the displayed answer
289.94 -> is the goal to achieve
the most accurate answer.
293.8 -> We'll use 114 over 76 as an example.
321.61 -> All right, so now that you know the basics
324.03 -> let's try a few simulations.
327.13 -> Listen closely and
write down your answers.
330.32 -> I will reveal the correct
answer once the simulation ends.
334.9 -> Here's the first one.
364.53 -> Try another.
386.77 -> Okay, and let's try one more.
416.67 -> So did you answer all of them correctly?
419.78 -> Great job.
421.15 -> Give yourself a huge pat on
the back for a job well done.
425.47 -> There's so much more to
learn about blood pressure,
427.77 -> especially when it comes
to the terminology,
430.25 -> ranges, and the many steps
involved in the process.
433.87 -> Continue to discover, review,
435.57 -> and practice as much as you can to master
438.2 -> the art of measuring
blood pressure correctly.
442 -> And there you have it.
443.79 -> You have learned to identify and interpret
446.59 -> the graduation markings
447.84 -> on an aneroid sphygmomanometer dial
450.96 -> and determine the systolic
and diastolic blood pressure
454.25 -> by reading the dial
455.37 -> and listening to the Korotkoff sounds.
