Reduced blood flow ... but its usually an artifact of measurement rather than real.
Your heart is about to explode and you die
When blood pressure is measured, it consists of two readings: systolic and diastolic pressure. The systolic pressure, the higher number, represents the pressure in the arteries when the heart beats and pumps blood. The diastolic pressure, the lower number, indicates the pressure in the arteries when the heart is at rest between beats. Together, these readings provide a comprehensive picture of cardiovascular health.
There are two types of blood pressure—systolic and diastolic—because they measure different phases of the heart's pumping cycle. Systolic pressure, the higher number, indicates the force of blood against the artery walls when the heart contracts and pumps blood. Diastolic pressure, the lower number, measures the pressure in the arteries when the heart is at rest between beats. Together, they provide a comprehensive view of cardiovascular health and how well the heart and blood vessels are functioning.
If you mean Systemic & Pulmonary, that's because they're separate systems. If you mean systolic & diastolic, then they're not different; they represent highest and lowest pressure of each stroke of the heart.
Systolic and diastolic pressures are both measurements of blood pressure, indicating the force of blood against artery walls during different phases of the heart's pumping cycle. They are both expressed in millimeters of mercury (mmHg) and are crucial for assessing cardiovascular health. Additionally, both values are influenced by factors such as blood volume, heart rate, and vascular resistance. Together, they provide a comprehensive picture of an individual's blood pressure status.
Systolic comes from the Greek word, "systole", which means to draw together or contract. Systolic pressure is the maximum pressure produced in the arteries when the left ventricle of the heart contracts.
Isobars that are close together indicate strong winds. This is because a steep pressure gradient exists in such areas, leading to a rapid change in atmospheric pressure over a short distance. As a result, air moves more quickly from high-pressure to low-pressure areas, producing stronger wind speeds. Conversely, widely spaced isobars indicate lighter winds.
Isobars are lines on a weather map connecting points of equal atmospheric pressure. When isobars are close together, it indicates a large pressure gradient, leading to strong winds and unsettled weather conditions, such as storms or high winds.
As noted, it is extremely important to make sure your health provider uses the correct size of blood pressure cuff for you. Using a regular cuff on a fat person has been found to artificially inflate blood pressure significantly. If they do not use the correct-sized cuff on you, they will be basing your medical diagnosis and treatment plan on INVALID DATA. It is essential that this number be accurate. It is particularly critical to have an accurate reading of blood pressure in pregnancy due to concerns about Pre-Eclampsia/Pregnancy-Induced Hypertension (PE/PIH). Outside of pregnancy, a borderline BP number is not pursued as vigorously, but in pregnancy most OBs get very nervous about borderline blood pressures, and will start very aggressive interventions very quickly. Because some cases of PIH progress rapidly to PE and can endanger the baby and the mother, OBs tend to be extremely interventive about borderline blood pressures in pregnancy. Therefore it is extremely important to have accurate data on which to base these critical decisions.
Yes, "under pressure" is a prepositional phrase. It consists of the preposition "under" and the noun "pressure," functioning together to indicate a condition or state. Prepositional phrases typically provide additional information about time, location, or circumstances in a sentence.
isobars are a measure of atmospheric pressure. variations in atmospheric pressure basically cause weather - high pressure vs low pressure, etc.
Isobars that are close together indicate stronger wind speed, where the wind blows parallel to the lines connecting points of equal pressure. The closer the isobars are together, the stronger the pressure gradient force, leading to faster winds.
