Answer: The first number recorded in a blood pressure measurement is the systolic pressure and represents the peak pressure generated by cardiac contraction. The second number is the diastolic pressure and represents the intravascular pressure during relaxation of the heart while it is filling. The difference between these two measurements is called the pulse pressure. So, for a normal BP reading of 120/80, there would be a normal pulse pressure of 40.
Answer: There are a number of factors that can cause a high diastolicreading. These include, but are not limited to, stress, poor diet,obesity, sedentary lifestyle, age, smoking, and alcohol. A highdiastolic reading with a normal systolic reading is known asisolated diastolic hypertension. If the diastolic reading is notbrought down soon, higher systolic readings can follow. It isimportant to discuss any abnormal blood pressure readings with yourdoctor.
Answer: you cant get rid of it but you can change it by going to menu, applications settings, camera settings, camera, then one of the options is shutter sound (probably for that phone) then change your sound.
Answer: If it only happens when you plug the mouse in (and not with other peripherals) it sounds like a hardware problem with the mouse USB cord. Try another mouse - if the problem cures itself - the mouse is faulty - if not, then the problem is in the computer itself.
Answer: Every version of OS X has been moving away from using the G4 chip since OS X was released. If the System Preferences screen on your machine will not enable sound then you face the choise of reverting your system to OS 9.X or buying a more modern machine that ships with at least Tiger (OS 10.2)
Answer: when pressure in the sphygmomanometer falls below systolic pressure, blood can again enter the artery. At first, blood enters only at peak systolic pressure, and the sound of blood pulsing through the artery becomes audible through the stethoscope. As the pressure falls further, the sound changes because the vessel is remaining open for longer periods. When the cuff pressure falls below diastolic pressure, blood flow becomes continuous, and the sound of the pulse becomes muffled or disappears completely.
Answer: SYSTOLIC: Relating to a systole or happening during a systole. But what is a systole? It is the contraction of the chambers of the heart(especially the ventricles) to drive blood into the aorta and pulmonary artery.
DIASTOLIC: Relating to a diastole or happening during a diastole. But what is a diastole ? The widening of the chambers of the heart between two contractions when the chambers fill with blood is called a diastole.
Answer: If you mean what causes the systolic to be high while the diastolic is normal or low the answer is hardening of the arteries. Normally as the pulse of blood comes through the artery the walls stretch to accommodate the wave of blood. As the arteries get stiffer instead of stretching they just cause the pressure to go up.
If yo are asking what causes high blood pressure then the answer is that we usually do not know. Age, salt intake, weight and lack of activity all contribute. Things like pain , anxiety and stimulants cal also make it go up. Occasionally there is a diagnosable and treatable medical condition that can be reversed but this is the exception.
Answer: Systolic, the top and high number, is the most important factor in blood pressure readings. It determines whether an individual has hypertension, or high blood pressure. Systolic is the maximum force exerted by the heart on blood vessels while diastolic is the resting phase of the heart between beats. Before the new millennium it was believed that diastolic was more important.
Answer: Systolic blood pressure (the top number) tells you how strong the pressure is when your heart beats. A higher top number is usually more cause for concern that the lower number.
Diastolic blood pressure (the bottom number) tells you how strong the pressure is when the heart is not beating. What this generally tells you is how elastic and resilient your system of vessels are. With age, this number gets lower- particularly after middle age.
