Assessment of blood pressure in brachial artery(two-step method)

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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
Pharmacodynamics in Geriatric Patients: Effects of Age01:27

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
Blood Flow01:29

Blood Flow

Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.
Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Summary

Older adults show increased brachial artery retrograde velocity with age, which is linked to reduced physical function. This finding highlights potential hemodynamic changes impacting mobility in aging populations.

Area of Science:

  • Gerontology
  • Cardiovascular Physiology
  • Biomedical Engineering

Background:

  • Aging is associated with physiological changes affecting vascular health and physical function.
  • Understanding the relationship between arterial hemodynamics and functional decline is crucial for interventions in older adults.

Purpose of the Study:

  • To investigate brachial artery flow velocity patterns in older adults.
  • To determine the association between these hemodynamic measures and physical function.

Main Methods:

  • Utilized high-resolution ultrasonography to measure brachial artery flow velocities and dimensions in 95 participants (mean age 84 years).
  • Assessed physical function using the Continuous Scale of Physical Function and Performance Test (CS-PFP10).
  • Analyzed correlations between hemodynamic parameters (e.g., retrograde velocity, vascular conductance) and CS-PFP10 scores, considering age.

Main Results:

  • Brachial artery retrograde velocity and pulse pressure showed a direct association with age.
  • Vascular conductance and the antegrade/retrograde velocity ratio were inversely associated with age.
  • Higher CS-PFP10 scores correlated with lower retrograde velocity, an association partly dependent on age.

Conclusions:

  • Brachial artery retrograde velocity increases with age in older adults.
  • These age-related hemodynamic alterations are linked to a decline in physical function.
  • Targeting hemodynamic changes may offer a pathway to improve physical function in the elderly.
