hey! there everyone .... here is the new ppt of topic BLOO PRESSURE which was aasinged by the CBSE for class 12 student boards project. i hope you all will like my ppt .............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................What Is Blood Pressure? (Sources: American Heart Association, National Heart, Blood, and Lung Institute) Blood pressure is the force of blood pushing against the walls of the arteries. It is determined by how much blood your heart pumps and how much resistance to the flow of blood occurs in your arteries. It is through the arteries that oxygenated blood is transported throughout your body. Blood pressure is high if resistance to blood flow is high – this means that blood is not able to easily be transported throughout your body! How is blood pressure measured? (Sources: American Heart Association, National Heart, Blood, and Lung Institute – (1) What Is Blood Pressure? & (2) What Are High Blood Pressure and Prehypertension?) .. When blood pressure is measured, two numbers are recorded: one for the systolic blood pressure and one for the diastolic blood pressure. The systolic pressure measures the pressure in the arteries when the heart beats (the heart muscle contracts). This is when your blood pressure is highest. The diastolic pressure measures the pressure in the arteries between heartbeats (the heart muscle is resting and refilling with blood). This is when your blood pressure is lowest. Blood pressure is usually expressed as a ratio of systolic to diastolic blood pressure. The units of blood pressure are typically millimeters of mercury (mm Hg). What Is High Blood Pressure (HBP/Hypertension)? (Sources: American Heart Association, Centers for Disease Control and Prevention – (1) About High Blood Pressure & (2) High Blood Pressure, Mayo Clinic, National Heart, Blood, and Lung Institute) High blood pressure, or hypertension, is a condition in which the force of blood flow against the walls of the arteries is strong, meaning the blood is having difficulty going through! This can occur if the amount of blood flow is large or if the walls of the arteries are narrow. Blood pressure usually rises and falls throughout the day, but if it stays elevated for an extended period of time, it can lead to health problems. Situations of isolated systolic high blood pressure are common – the diastolic blood pressure does not need to be high for you to have high blood pressure! The systolic blood pressure usually increases with age (unlike the diastolic pressure, which usually decreases

1.  Blood pressure is the force of blood pushing
against the walls of the arteries. It is determined
by how much blood your heart pumps and how
much resistance to the flow of blood occurs in
your arteries.
 It is through the arteries that oxygenated blood
is transported throughout your body.
 Blood pressure is high if resistance to blood flow
is high – this means that blood is not able to
easily be transported throughout your body!

2.  When blood pressure is measured, two numbers are
recorded: one for the systolic blood pressure and one
for the diastolic blood pressure.
 The systolic pressure measures the pressure in the
arteries when the heart beats (the heart muscle
contracts). This is when your blood pressure is
highest.
 The diastolic pressure measures the pressure in the
arteries between heartbeats (the heart muscle is
resting and refilling with blood). This is when your
blood pressure is lowest.

3. High blood pressure, or hypertension, is a condition in
which the force of blood flow against the walls of the
arteries is strong, meaning the blood is having
difficulty going through! This can occur if the amount
of blood flow is large or if the walls of the arteries are
narrow.
Blood pressure usually rises and falls throughout the
day, but if it stays elevated for an extended period of
time, it can lead to health problems.
The diastolic blood pressure decreases after around age
55, so this number is an especially important
hypertension number for younger people.

4. Primary hypertension: is the type for which the cause
cannot be identified. It is also known as essential
hypertension.
Secondary hypertension: is caused by pre-existing or
underlying conditions.
 Kidney problems or abnormality.
 Adrenal gland tumors.
 Structural abnormality of the aorta.
 Certain congenital defects in blood vessels.
 Illegal drugs.

5.  Hypertension increases the risk for other conditions,
specifically heart disease and stroke, two of the
leading causes of death in the U.S. Other health
conditions for which hypertension is a risk factor or
indicator include:
Aneurysm.
Angina.
Damage to the heart and coronary arteries.
Erectile dysfunction.
Fluid in the lungs.
Heart failure.
Stroke.

6. o Age.
o Alcohol intake.
o Chronic conditions.
o Diabetes.
o High cholesterol.
o Kidney disease.
o Sleep apnea.
o Diet, obesity or overweight.
o Too much salt.
o Family history, race.

7.  Low blood pressure may be due to:
 Pregnancy.
 Decreases in blood volume.
 Certain medications.
 Heart or endocrine problems.
 Severe infection or allergic reaction.
 Neurally mediated hypotension.
 Nutritional deficiencies.

8.  Monitoring blood pressure can be done through regular blood
pressure measurements. Additionally, lifestyle modifications
can be implemented to prevent or help lower high blood
pressure.
 Lifestyle Recommendations.
 Don’t smoke.
 Eat a healthy diet!
 Eat fruits and vegetables (sources of potassium and fiber) as
well as whole grains and low-fat dairy foods.
 Eat foods low in cholesterol and saturated and trans fats.

9.  The measurement of blood pressure is one of the most
commonly performed procedures in clinical medicine and
should be done carefully.
 The main causes of misleading readings should be highlighted
in training.
 All those who measure blood pressure should be assessed on
the practical aspects of the procedure.
 Defective or inappropriate equipment must not be used. A
phased maintenance programme is essential and inexpensive.
 A maintenance programme should be defined for each clinical
area where blood pressure measurements are made.
