Systolic
systolic
The systolic pressure is measured at the first Karotkoff sound (stage I), it is the first tapping noise that you hear with a stethoscope when taking a manual blood pressure.
If a balloon is removed without deflating it first, the sudden change in pressure may cause it to burst. This is because the air inside the balloon will expand rapidly as it is taken out of the surrounding air pressure.
Korotkoff sounds are the series of tapping or knocking sounds heard during measurement of blood pressure using a stethoscope. They correspond to the turbulent blood flow in the arteries as the cuff pressure is gradually released. The first sound (Phase I) indicates systolic blood pressure, while the disappearance of sounds (Phase V) indicates diastolic blood pressure.
The change in sound heard through the stethoscope during blood pressure measurements is primarily due to the Korotkoff sounds, which occur as blood begins to flow through the brachial artery when the occluding pressure of the cuff is released. As the cuff pressure decreases, these sounds transition from muffled to distinct tapping noises, indicating the systolic blood pressure when the first sound is heard and the diastolic pressure when the sounds disappear. This method allows healthcare providers to accurately gauge blood pressure by listening for these auditory cues.
The first number is called your systolic blood pressure and the second is called your diastolic. The Systolic is the pressure in your arteries when the ventricles are contracting - so it is the maximum pressure that the heart exerts on the arteries. The diastolic is the pressure when the heart is relaxed - so it is the minimum amount of pressure.
Systolic
The first number is your systolic pressure, which is the pressure when your heart is contracting and pumping blood out. The second, lower number is your diastolic pressure, which is the blood pressure when your heart is relaxing and filling up with blood, not pushing any blood out. I think you've figured it out by now...blood being pushed out will be at a higher pressure, hence the higher first number :)
The sounds heard while measuring blood pressure in this way are called the Korotkoff sounds, and undergo 5 phases: # initial 'tapping' sound (cuff pressure = systolic pressure) # sounds increase in intensity # sounds at maximum intensity # sounds become muffled # sounds disappear
Blood pressure is the force or pressure that blood puts on the walls of your arteries as it goes through your body. Blood Pressure readings are usually written as 2 numbers. The first and higher number is called systolic pressure. It is the pressure in your blood vessels when your heart beats. The second and lower number is called the diastolic pressure. It is the pressure in your blood vessels when your heart is resting between beats.
A person who is apt in measuring blood pressure using the sphygmomanometer records two numbers. The first one is the systolic blood pressure while the second one is the diastolic blood pressure.
The first number in a blood pressure reading is the systolic blood pressure. It represents the pressure in the artery when the heart is contracting. The second number is the diastolic blood pressure, and represents the pressure when the heart is relaxing.
