There will be no systolic sound if blood is flowing freely. This occurs when there is no measurable constriction of an artery.
The disappearance of sound is caused by blood flowing freely. The blood flows freely because there is no constricted artery.
the systolic sound is caused by ventricular contraction
systolic
Rapid potassium infusion causes diastolic and not systolic cardiac arrest.
The disappearance of sound in a pulse can be attributed to several factors, including attenuation, which is the reduction of sound intensity as it travels through a medium due to absorption and scattering. Additionally, the distance from the sound source plays a significant role; as sound waves propagate, they spread out, leading to a decrease in amplitude. Environmental factors like temperature, humidity, and obstacles can also affect sound propagation, further contributing to its diminished audibility.

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.
diastolic pressure
it calms you and causes your blood to slow down.
The potential causes of the sudden disappearance of bees in 2016 included pesticide use, habitat loss, and climate change. The consequences of this disappearance could have been a decline in crop pollination, leading to reduced food production and biodiversity loss.
