How does a hemorrhage affect blood pressure?
Blood pressure is proportional to blood volume ie. The greater the blood volume is, the higher the blood pressure will be. This is because there will be a greater volume of blood flowing through the blood vessels which means that a greater pressure will be exerted on the walls of the blood vessels, which means increased blood pressure. However, there are many factors which contribute to changes in blood pressure, blood volume is just one of these factors.
Is blood pressure common to female?
no
What the definition of systolic and dystolic?
When taking blood pressure there are two readings, eg 120/70. The first reading (120) is the systolic blood pressure and the second reading (70) is the diastolic blood pressure. The systolic blood pressure is always higher than the diastolic.The systolic reading is when the heart muscle is contracting, pushing blood through the arteries, therefore creating more pressure (hence the higher number) in the arteries.The diastolic reading is when the heart is relaxed and refilling with blood, ready for the next beat, therefore exerting less pressure on the arteries (hence the lower number)
Is blood flow measured in mm hg?
The "flow" isn't, but the pressure is.
What are the composition of vital signs?
temperature, pulse, respiration, blood pressure and pain
When you take someone's blood pressure you are measuring the pressure during the contraction and relaxation phases of the heart muscle?
true
When taking a blood pressure the systolic pressure is the pressure reading when the?
Blood pressure readings are always expressed as two values, one high and one low, representing the squeeze (systolic) and relax (diastolic) phases of the heart's pumping. The units of blood pressure are millimetres of mercury - that might seem a strange kind of measurement but it's really just seeing how far up a tube the pressure can push a column of mercury. So the full expression is, for example, 120 millimetres of mercury or 120 mmHg.
What is the lowest pressure exerted by blood in your arteries is your- blood pressure?
The lowest pressure exerted by blood in your arteries is your diastolic blood pressure.
What are the 2 phases of blood?
plasma, and formed elements
Does heat affect blood pressure?
Increases in body temperature cause a corresponding increase in respiratory rate and heart rate because there is an increase in metabolic needs of the body. As regards blood Pressure, I believe the blood pressure goes down as a result of an Increase in body temperature. The body generates a lot of heat that decreases body hydration level and a result the body becomes dehydrated and the BP decreases. Increase with fever, necessitating more oxygen. The client who has a decrease in body temperature will experience a decrease in respiratory rate, Heart rate and Blood pressure.
Blood pressure is a measurement of what?
Blood pressure is the measure of the force of the blood against the walls of the blood vessels that it is contained in. Blood pressure is usually expressed in mmHg as the systolic pressure divided by the diastolic pressure.
Is blood pressure the pressure of blood in the arteries?
Yes, blood pressure is a measure of the pressure exerted on your arterial walls as the heart pumps blood throughout the body (systolic) over the pressure when your heart is relaxed (diastolic).
What is blood pressure used to evaluate?
Your systole and diastole (or systolic and diastolic pressure). Systolic pressure is the pressure your blood exerts on blood vessels when your heart pumps out blood while diastolic pressure is the pressure your blood exerts on blood vessels when your heart is at rest(in between pumps). Blood pressure is stated as systolic pressure/diastolic pressure. The normal BP is 120/80 mmHg.
What is blood pressure-?
Blood pressure is the pressure of the blood in the circulatory system, often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.
What is a blood pressure hill?
blood pressure gradient
NORNAL BLOOD PRESSURE?
NORMAL BLOOD PRESSURE
What happens to blood pressure as you exercise?
Blood pressure increases during excercise because the heart rate increases to allow more blood to get to the working muscles. However: Moderate exercise, i.e. walking, has benefits for people suffering high blood pressure. Research has shown that walking several times a week for at least half an hour can help lower high blood pressure. It is best to avoid continued strenuous exercise, however - high BP causes greater strain on the arteries, and in strenuous exercise, one is making one's heart work harder.
