Pulse01:16

Pulse

573
When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
The pulse serves as a clinical...

Pulse amplitude and quality01:17

Pulse amplitude and quality

1.8K
Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Area of Science:

  • Cardiovascular Physiology
  • Biomedical Engineering
  • Mathematical Modeling

Background:

  • Arterial pulse waveforms offer vital cardiovascular insights.
  • Existing mathematical models lack physical meaning, and physical models lack individuality.
  • There is a need for interpretable and individualized arterial pulse wave models.

Purpose of the Study:

  • To enhance the interpretability of mathematical models for arterial pulse waves.
  • To develop a novel method for pulse wave decomposition with clear physiological significance.
  • To link model parameters to hemodynamic characteristics and clinical indices.

Main Methods:

  • Developed novel 3-term fitting functions individualized by physiological parameter assignment.
  • Utilized peak times of reflected and dicrotic waves for parameterization.
  • Performed nearly 10,000 pulse fitting experiments to validate the method.

Main Results:

  • The proposed method significantly outperforms standard methods in fitting accuracy.
  • The model successfully decomposes pulse waves into sub-signals with physiological meaning.
  • Parameters derived from the model correlate with hemodynamic characteristics and the peripheral augmentation index (pAI).

Conclusions:

  • The new method improves the individuality and accuracy of arterial pulse wave models.
  • Enhanced parameter interpretability is achieved by linking them to physiological and clinical significance.
  • This approach is valuable for future pulse wave decomposition studies incorporating hemodynamic characteristics.
