How?
How do we make our heart rate go up?
Give one example.
Exercise!! (Running, walking, jumping)
Anything that challenges our muscles!
How many times does 15 seconds, go into one minute?
Remember, one minute is equal to 60 seconds.
Four!
15 x 4 = 60
Make your heart rate go up at least 20 bpm!
Get moving!
What vital sign do we take, using a scale?
Weight!
Why is oxygen so important for our body?
We need oxygen to survive
Oxygen provides the cells in our body with the energy they need in order to grow, reproduce, and turn food into energy.
How does our body help to keep us warm when we get too cold?
Blood vessels constrict (get smaller in width) and sends more blood to our vitals organs to protect them from becoming too cold to function.
We also shiver, generating movement and boosting your body's surface heat.
If I take 5 breaths in 15 seconds,
how many breaths would I take in one minute?
Sixteen!
5 x 4 = 20
Take my respiration rate!
Remember, this is how many times I breathe in one minute. So if we count out breaths for 15 seconds, we can then multiply by 4!
4 x (# of breaths) = respiration rate
BONUS: Does our respiration rate go up or down, after exercise?
What do we use to measure our temperature?
Thermometer!
Why do adults have higher blood pressures than children?
As our bodies grow, our brain gets further away from our heart. In order for the blood to reach the brain, it need to work against gravity.
This requires more pressure (or force) to be put into pushing the blood into the vessels, to make sure that it reaches the brain.
BONUS: Based on this information, which animal in the wild, do you think would have the highest blood pressure?
When we get too hot, the hypothalamus in our brain tells our body to do certain things in order to help us cool down.
How does our body help us to cool down when we are too hot?
WE SWEAT!
Signals are sent out telling our blood vessels to expand (dilate), bringing blood to the surface and allowing for the release of heat through vaporization.
If my oxygen was only at 90 percent, how many more numbers would it need to increase, in order to be in what is consider the "normal range?"
Anywhere from 5 to 10
Remember, 95-100 is consider a normal percentage of oxygen saturation
Take my temperature, using the thermometer correctly and tell me if I have what would be considered to be a "fever."
low grade fever is considered to be 99-101.4
Name 3 important vital signs that we take, in order to monitor our health?
Blood pressure
Respiration rate
Pulse / Heart rate
Temperature
Oxygen
BONUS: Which one is missing?
(hint: it's not height)
Why is it important for our legs to be flat on the floor while having our blood pressure checked?
It can increase your blood pressure!
This is because the heart now has to work slightly harder (with more force) to make sure the blood is reaching those muscles.
How does a thermometer read our temperature?
What is it actually sensing the temperature of inside our body?
The blood inside of our arteries
120/80 is considered to be the standard, or "normal" blood pressure; though this can vary a lot depending on the individual.
If the top number is 120 (full pressure) and the bottom number is 80 (relaxed pressure), how much more pressure is being exerted at full force compared to it's relaxed state?
120 - 80 = 40 mm Hg
BONUS: What does "mm Hg" mean?
Make your heart rate go up 70 beats per minute!
RUNNNNNNNN!!!!!!
There are two ways to take our blood pressure, Automatic and Manual.
Point out to me the equipment that you need for each way.
Automatic Blood pressure (machine)
Manual blood pressure (cuff w/ gauge and stethoscope)
Why do we place the blood pressure cuff where we do on the arm? Why is this location, and the way the cuff is lined up, matter?
The blood pressure cuff is determining what the pressure of the blood flow is inside of your Brachial artery.
How can we measure someone's heart rate if we are without a pulse ox or a BP machine?
Give one example.
Listening: Placing a stethoscope over heart as it beats and counting.
Feeling: We can feel the blood pumping into our vessels by placing one finger gently onto the wrist, just below the thumb, over what is called the Radial artery.
If my heart beats 51 times in 30 seconds,
it will beat 102 times in 60 seconds.
How many times will it beat in TWO minutes?
204!
51 x 4 = 204
Take my pulse without using a pulse ox or BP machine, and get within 5 beats of the correct answer!
Remember there are two ways to do this!!
We can either feel it using the radial artery on the wrist or we can hear it using a stethoscope over the heart.
What two vital signs are we taking, when we use a "pulse-oximeter?"
Oxygen
Pulse / heart rate
WHY are vitals so important?
What are the two reasons we take them?
To make sure everything is working as it should
AND
To know if something is wrong
