Blood Pressure By: Kayla White & Malique Fleming
What is Blood Pressure? • Pressure of the blood in the circulatory system, • often measured for diagnosis since it is related to the force • and rate of the heartbeat and the diameter and elasticity of the arterial walls.
Types of Blood Pressure â€˘ Systolic- is the highest pressure created by the contraction of the heart muscle and the elastic recoil of the aortic artery as blood surges through it. â€˘ Diastolic- is when the ventricles relax between beats. It reflects the resistance of all the small arteries throughout the body and the load against which the heart must work.
Categories of Blood Pressure. â€˘ Hypotension- Is the low blood pressure and occurs when blood pressure during and after each heartbeat is much lower than usual.Ex:90/60 â€˘ Hypertension- Is the high blood pressure and is a measurement of the force against the walls of your arteries as your heart pumps blood through your body. Ex:120/80
Symptoms of High Blood Pressure â€˘ Hypertension- is the medical term for high blood pressure. â€˘ It is known as the "silent killer" since it has no initial symptoms but can lead to long-term disease and complications.
Symptoms of Low Blood Pressure • Hypotension-when the flow of blood is too low to deliver enough to the • oxygen and nutrients to vital organs • such as the brain, heart, and kidney.
Prehypertension â€˘ Prehypertension is an American classification for cases where a person's blood pressure is elevated above normal but not to the level considered to be hypertension high blood pressure.
Symptoms of Stage 1 Hypotension • • • • • • •
Dull headaches Dizzy spells Nosebleeds Diabetes Strokes Heart Attacks Heart Failure
Preventing Hypertension • You have to focus on the factors that can be changed when your family has a long line of Hypertension. • Maintain a Healthy Weight • Eat a balanced diet • Exercise • Limit alcohol • Monitor your blood pressure
6 ways to control high blood pressure • • • • • •
Your lifestyle Lose extra pounds off of your waistline Exercise Be a smart shopper Reduce sodium intake Eat fewer labeled foods
Causes of Hypotension • • • • • • • •
medication pregnancy Diabetes Pneumonia Heart conditions Dehydration Vomiting Diarrhea
Orthostatic Hypotension • include dizziness • euphoria or dysphoria • bodily dissociation, distortions in hearing, lightheadedness, • nausea, headache, blurred or dimmed vision • possibly to the point of momentary blindness
Secondary High Blood Pressure • Is caused by a specific disorder of a particular • organ or blood vessel, • such as the kidney, adrenal gland, or aortic artery.
Renal Hypertension â€˘ It is caused by a problem in the kidneys. One important cause of renal hypertension is narrowing stenosis of the artery that supplies blood to the kidneys renal artery.
White Coat Blood Pressure • Single elevated blood pressure reading in the doctor's office – can be misleading because the elevation may be only temporary.
• Caused by a patient's anxiety related to the stress of the examination and fear that something will be wrong with his or her health. • Initial visit to the physician's office is often the cause of an artificially high blood pressure – May disappear with repeated testing after rest and with follow-up visits and blood pressure checks.
• One out of four people that are thought to have mild hypertension actually may have normal blood pressure when they are outside the physician's office.
Borderline High Blood Pressure â€˘ Mildly elevated blood pressure higher than 140/90 mm Hg at some times, and lower than that at other times. â€˘ As in the case of white coat hypertension, patients with borderline hypertension need to have their blood pressure taken on several occasions and their endorgan damage assessed in order to establish whether their hypertension is significant. â€˘ May have a tendency as they get older to develop more sustained or higher elevations of blood pressure.
Isolated Systolic Hypertension â€˘ Is defined as a systolic pressure that is above 140 mm Hg with a diastolic pressure that still is below 90. â€˘ This disorder primarily affects older people and is characterized by an increased wide pulse pressure. â€˘ The pulse pressure is the difference between the systolic and diastolic blood pressures.
