Pulse

Pulse

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

Pulse

The pulse is one of the most fundamental physiological indicators of the body's cardiovascular health. It is the rhythmic expansion and contraction of the arterial walls in response to the pressure generated by the heart's pumping action.
Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls...

Assessing Blood pressure using a doppler ultrasound

Assessing Blood pressure using a doppler ultrasound

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.

Equipments Used To Measure Blood Pressure

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...

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
Medical instrumentation

Background:

Aortic stiffening is a significant indicator of cardiovascular risk, associated with conditions like myocardial infarction, heart failure, atherosclerosis, and stroke.
Current gold standard methods for arterial stiffness evaluation, such as pulse wave velocity (PWV), often measure propagation over combined arterial segments, lacking aortic-specific assessment.
There is a need for non-invasive techniques that can specifically evaluate aortic stiffness.

Purpose of the Study:

To investigate the potential of Inductive Plethysmography (IP) for measuring aortic stiffness.
To assess the feasibility of using thoracic and abdominal IP recordings for estimating aortic pulse wave velocity (PWV).

Main Methods:

A comparative analysis was performed between PWV estimated using IP and PWV measured from the arm.
The study involved 11 healthy volunteers.
Inductive Plethysmography (IP) was utilized to capture signals related to aortic volume changes.

Main Results:

A significant linear correlation (r = 0.86, p<0.001) was observed between PWV estimated from IP and PWV measured from the arm.
These findings suggest that IP can provide reliable estimations of aortic stiffness.

Conclusions:

Inductive Plethysmography (IP) demonstrates potential as a non-invasive method for evaluating aortic stiffness.
The promising correlation supports further investigation of IP for aortic PWV measurement, particularly in pathological populations.
