Blood Pressure, Heart Rate & Pulmonary/Systemic Circulation

By: Jori Stanton


´╗┐Blood Pressure:

- The force the blood exerts against the blood vessel walls.
- The pumping of the heart makes the blood flow.
- A wave that travels from the heart throughout the arteries is pressure which is the pulse.
Systolic Pressure;
-The maximum pressure exerted by the blood against the artery wall.
- It is ventricular contraction.
- Normal pressure is 120 mmHg.
- First beat you hear
Diastolic Pressure;
- The lowest pressure in the artery
- It is ventricular relaxation.
- Normal pressure is 80 mmHg.
- Last beat you hear
- Denominator
Pulse Pressure is determined by calculating the difference between Systolic Pressure - Diastolic Pressure.
(Pulse Pressure is the throb that you feel.)
The Sphygmomanometer is what you use to determine the Blood Pressure by Systolic and Diastolic Pressure.
The Cuff constricts an artery to cut off blood flow.
The Bulb is what you press to inflate the cuff.
The Stethoscope is what you listen to, to hear the blood pressure sounds.

Heart Rate:

-The number of beats per minute. Normal resting heart rates are determined with age, sex, size and cardiovascular condition. Heart rate can be determined
by taking your pulse. Normal Heart rate for an averaged size adult is in the range of 60-100 beats per minute. Normal Heart rate for infants is 100-160 beats per
minute. Normal Heart rate for children is 80-120 beats per minute.
-To take your Pulse you take your first finger and second finger and you could put them on your wrist but most people place them on there neck and feel around for the thumb. Once you feel that thob then you count every beat for a minute.

Pulmonary Circulation:

- Happens in the right side of the heart with oxygen-poor blood turning into oxygen-rich blood.- After leaving the heart it goes ONLY to the lungs.- Leaves the heart through the PULMONARY ARTERIES.- Goes back into the heart through the PULMONARY VEINS.

Systemic Circulation:

- Happens in the left side of the heart with oxygen-rich blood then turns back into oxygen-poor blood.- After leaving the heart it goes to everywhere in the body EXCEPT the lungs.- Leaves the heart through the AORTA.- Goes back into the heart through the Superior Vena Cava and the Inferior Vena Cava.
