Pulse01:16

Pulse

2.5K
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

3.5K
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...

Pulse Assessment Sites01:11

Pulse Assessment Sites

3.1K
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Assessing Blood pressure using a doppler ultrasound

2.8K
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Area of Science:

  • Integrative Medicine
  • Biomedical Engineering
  • Traditional Chinese Medicine Diagnostics

Background:

  • Traditional Chinese Medicine (TCM) relies on five diagnostic methods, with palpation (pulse diagnosis) being paramount for assessing patient health.
  • Pulse diagnosis involves a physician manually assessing wrist artery pulse characteristics.

Purpose of the Study:

  • To develop and validate a novel, objective method for classifying pulse types using a specialized instrument.
  • To enhance the accuracy and efficiency of pulse diagnosis in TCM through quantitative analysis.

Main Methods:

  • Utilized a specialized pulse measuring instrument to capture measured pulse waves (MPWs).
  • Segmented MPWs into arterial pulse wave curves (APWCs) using an image processing technique.
  • Extracted key pulse features, including slopes and periods at specific points on the APWC, using three proposed algorithms.

Main Results:

  • The proposed algorithms demonstrated superior accuracy in feature extraction compared to previous methods.
  • Quantitative analysis of APWC features provided objective pulse type classification.
  • The developed method showed significant improvements over existing techniques in terms of accuracy and data volume reduction.

Conclusions:

  • The novel pulse wave analysis method offers a more accurate and efficient approach to TCM pulse diagnosis.
  • This technology has the potential to significantly reduce diagnostic time for physicians and decrease data processing requirements.
