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.
CHECK YOUR BLOOD PRESSURE Korotkoff sounds are certain specific sounds heard when the arteries decompress and move the blood along them. They were invented by a Russian professor - Nikolai Korotkoff in the early 20th century during the 1st world war and remain the best ausculatory way to measure arterial blood pressure. When an artery is totally compressed, no sounds can be heard at all as no blood is moving. As the artery is slowly decompressed, certain sounds are heard which indicate a way of judging the level of pressure in the artery. In order to slowly decompress the artery we need to use an inflatable sphygmomanometer cuff and a stethoscope. The cuff is pumped up until no sound can be heard. Then the cuff is slowly deflated and the sounds occur: They occur in four stages : silence-tapping-thumping-muffled-silence again when the cuff is fully deflated and the artery is completely unobstructed. When the first sound is heard - the tapping, the reading on the sphygmomanometer is taken to be systolic pressure. The moment all the sounds disappear and you are left with silence again, the reading on the sphygmomanometer is taken as diastolic pressure. This is the way by which your blood pressure will always be taken at your local GP or health clinic. The standard BP is 120/80 which is systolic/diastolic. However it is likely that people will have blood pressure values of near that value and still be perfectly healthy.
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.
Use a blood pressure cuff (sphygonometer, or something). The reading will be something like 120/90 where the higher number is the pressure of the heartbeat (systolic) and the lower number is the pressure between beats (diastolic).
The A has a short A sound, and the I has a short I sound.
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 loud tapping sound can be caused by a complete heating of the engine. Worn tappets can also cause the tapping sound.
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
No. There is only a short A sound and a short I sound.
