Equipments Used To Measure Blood Pressure

2.7K
Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Pulse01:16

Pulse

1.5K
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

2.6K
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 rhythm01:30

Pulse rhythm

1.1K
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Pulse Oximetry01:24

Pulse Oximetry

1.0K
Pulse oximetry, or SpO2, is a non-invasive method for continuously monitoring arterial oxygen saturation (SaO2). This procedure involves attaching a probe or sensor to the patient's fingertip, forehead, earlobe, or nose bridge. The sensor works by detecting changes in oxygen saturation levels through light signals generated by the oximeter and reflected by the pulsing blood under the probe.
Purpose
Average SpO2 values are greater than 95%. If the readings fall below 90%, it indicates that...

Area of Science:

  • Biomedical Engineering
  • Traditional Chinese Medicine (TCM)

Background:

  • Traditional Chinese Medicine (TCM) relies on pulse diagnosis, a subjective method.
  • Existing pulse signal collection methods lack standardization and objectivity.
  • International standards for pulse graph force transducers (ISO 19614:2017-05) necessitate objective measurement tools.

Purpose of the Study:

  • To develop a specialized force sensor component for objective and comprehensive collection of pulse physiological signals.
  • To meet industrialization requirements for pulse signal acquisition devices.
  • To align pulse signal measurement with international standards.

Main Methods:

  • Designed and developed a novel force sensor component based on TCM pulse principles and international standards.
  • The sensor is capable of measuring pulse amplitude and width signals.
  • Integrated three sensors for simultaneous measurement across the 'cun, guan, chi' positions, enabling "three body parts and nine pulse-taking sites" synchronous acquisition.

Main Results:

  • The developed sensor component meets industrialization requirements for pulse signal collection.
  • Verification results confirm adherence to relevant international standard requirements.
  • Achieved a consistency of 92.3% when compared to the diagnostic results of clinical TCM experts.

Conclusions:

  • The developed force sensor component enables objective and standardized pulse signal acquisition in TCM.
  • The sensor technology aligns with international standards for pulse graph force transducers.
  • This innovation demonstrates high consistency with expert clinical diagnoses, paving the way for wider adoption in TCM practice and research.
