What does the amplitude of a pulse mean?

What does the amplitude of a pulse mean?

pulse amplitude: The magnitude of a pulse parameter, such as the field intensity, voltage level, current level, or power level.

What is reflection amplitude?

In physics and electrical engineering the reflection coefficient is a parameter that describes how much of a wave is reflected by an impedance discontinuity in the transmission medium. It is equal to the ratio of the amplitude of the reflected wave to the incident wave, with each expressed as phasors.

What is the normal pulse amplitude?

Pulse/heart rate is the wave of blood in the artery created by contraction of the left ventricle during a cardiac cycle. The strength or amplitude of the pulse reflects the amount of blood ejected with myocardial contraction (stroke volume). Normal pulse rate range for an adult is between 60-100 beats per minute.

What is a reflected sound wave called?

Reflection of sound waves off of surfaces can lead to one of two phenomena – an echo or a reverberation. A reverberation often occurs in a small room with height, width, and length dimensions of approximately 17 meters or less.

What controls the amplitude of a pulse?

Pulse amplitude or volume Amplitude is a reflection of pulse strength and the elasticity of the arterial wall (Dougherty and Lister, 2004). The amplitude may change from strong to weak as a result of dysrhythmias or respiration.

What happens if the amplitude of a wave is doubled?

The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy.

What affects pulse amplitude?

The amplitude of pulse reached a maximum when the intravascular pressure and externally applied pressure were equal, and the P-H curve moved to the right as the inner pressure of the blood pressure increased. The pulse rate is the heart rate.

Is reflected or returned sound?

An echo is a sound wave that has been reflected or otherwise returned with sufficient magnitude and delay to be detectable as a wave distinct from that which was directly transmitted. In layman’s terms, an echo is a reflected sound wave that is audibly distinct from the source sound.

What are two options wave reflecting examples?

Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection.
