Heart Rate
What does heart rate tell you? Tells you part of the
patient’s story – how your body is being supplied by oxygenated blood
Where can you measure heart rate? 11 sites, 8 discussed last
class How do you describe
(document) heart rate? Site, rate, rhythm, depth
Respiratory Rate
Describe the process of breathing Inhalation and expiration: exchange of
gases in the body What does respiratory rate tell you?
Tells you how much oxygen you may need, and how much carbon dioxide to expel
How does respiratory rate relate to heart rate? Hold your breath Your body needs oxygen, but needs to also
get rid of gas wastes: CO2
Blood Pressure
What is blood pressure? A ratio of the pressure in your arteries when
your heart contracts & relaxes Systolic vs diastolic
What is hypotension vs hypertension? Hypo – below normal, ie. shock Hyper – above normal, ie. cardiovascular
disease What does blood pressure tell you?
Tells you whether oxygenated blood is getting delivered properly
Temperature
What does temperature tell you? The body self-regulates its temperature
to ensure cellular reactions work best What is hypothermia vs
hyperthermia? Temperature below or above normal can
seriously affect body function What is the difference between core
and peripheral temperature? Core: taken by ear (T) & rectum (PR) Peripheral: taken by armpit (Ax), mouth
(PO)
Let’s Take Some Vitals!
Manual blood pressure 1) Make sure patient has not been doing
any strenuous activity for about 5 minutes.
2) Take cuff and secure it around patient’s arm, placing the tubing centre to the patients brachial artery site
3) Locate the radial pulse, and inflate the cuff until you cannot feel the pulse anymore (obliteration), making note of the mmHg
Let’s Take Some Vitals!
Manual blood pressure continued 4) Now place your stethoscope on this
site and listen for a pulse. Inflate cuff above the obliteration point by 30-40mmHg.
5) Slowly deflate cuff at 2-3mmHg per second, and make note when you begin to hear the pulse again. That’s your systolic!
6) Continue to deflate and make note when you no longer hear the pulse. That’s your diastolic!

There are 11 sites to palpate pulse. 8 were in the last presentation: name 3 of these sites.

HR 500
What are the 4 components of documenting of heart rate?
1) Site 2) Rate 3) Rhythm 4) Depth

RR 300
Name 2 of the 3 components of documenting respiratory rate.
1) Rate 2) Rhythm 3) Depth

RR 400
What is the process in which your diaphragm flattens and chest expands allowing exchange of oxygen in your lungs?
Inhalation
Back to the Board
RR 500
Name 2 things that can affect your ability to breath: Bonus points if you can explain how.
Airway is obstructed Lung tissue is poor (ie. inflammation,
thickened) Lung cannot inflate properly (ie.
collapsed, pressure against lung space)

Temp 400
What is the difference between core and peripheral temperatures?
Core refers to temperatures closest to internal organs
Peripheral refers to temperatures away from internal organs
Back to the Board
Temp 500
Which type of temperature sites is the most accurate? Bonus points if you can explain why.
Core temperature sites such as tympanic & rectal
Because they are a better at measuring the temperature of your internal organs and less influenced by fluctuations of your environment

BP 200
What is the unit of measure for blood pressure?
mmHg or “millimetres of mercury”
Back to the Board
BP 300
What is the difference between systolic & diastolic pressures?
Systolic is a measures of the pressure in the arteries when the heart contracts
Diastolic is a measure of the pressure when the arteries relax

BP 500
Give 3 symptoms of hypotension.
Dizziness, light-headedness, syncope (fainting), cold/clammy skin, fatigue, shallow breathing, blurred vision, lack of concentration, nausea

Critical Thinking 600
BEFORE taking vital signs, what are some observations you can make that may affect how you interpret your findings?
Back to the Board
Critical Thinking 700
A 20 year old man comes into the ER with a stab wound to the stomach. His vitals are T-37.2*C (PO), BP-88/60, HR-121, RR-24. Explain the relationship between his blood pressure and his heart rate.
