Difference Between Systolic Pressure And Stethoscope

The things that count account for this difference between systolic pressure when the sound began, the stethoscope user heard it, and the computer operator pressed the event marker keystroke is because how fast sound travels. This comes into play because first the person using the stethoscope uses it, and he/she is not going to be able to react immediately to inform the computer user. There is a delay when the stethoscope user hears it from when the first sound begins, and then there is a delay when the stethoscope user lets the computer user know they heard the sound, and then the computer user does not react instantaneously when clicking the keystroke, it takes time. This difference would be observed in other similar set-ups because no one has perfect reaction time, and the only way this set up would work if a machine was programmed to perform these actions within a computer system, where no button click would be involved, because when you have to click a button there is an inherent delay.
The way this effects your pulse pressure is that it increases it. In a healthy person, you would expect their systolic pressure to go up, their diastolic pressure to change a little, and their pulse pressure to be a little higher due to the increases in systolic pressure which would affect the pulse pressure. Three sources of error in the indirect method of determining systemic arterial blood pressure are the differences in hearing time between each operator, reaction time, of each operator, and each operator having to perform a mechanical action before beginning the recording of data. An equation that relates flow, pressure, and resistance, to define mean arterial pressure is Mean Arterial Pressure = Diastolic Pressure + (1/3 Pulse
