Assessment of the Cardiovascular System III: Palpation01:27

Assessment of the Cardiovascular System III: Palpation

189
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Fluid Movement Between Compartments01:18

Fluid Movement Between Compartments

459
The force applied by fluids against a surface, known as hydrostatic pressure, initiates the transfer of fluid among different compartments. Within our blood vessels, the blood's hydrostatic pressure is a result of the heart's pumping action. At the arteriolar end of capillaries, hydrostatic pressure (capillary blood pressure) exceeds the opposing colloid osmotic pressure created primarily by plasma proteins like albumin. This discrepancy in pressure propels plasma and nutrients from the...

Veins as Blood Reservoirs01:10

Veins as Blood Reservoirs

2.9K
Veins, while chiefly responsible for circulating blood back to the heart, also function as storage vessels for blood. They house approximately 64 percent of the body's total blood volume, a feat made possible by their high capacitance—the inherent ability to expand and accommodate large volumes of blood, even under low pressure. The large diameter and thin walls of veins augment their distensibility, significantly more so than arteries, due to their classification as capacitance...

Venous Return01:04

Venous Return

2.8K
The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

Pre-Procedural Guidelines for Assessing Blood Pressure01:10

Pre-Procedural Guidelines for Assessing Blood Pressure

520
Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Summary

Intermittent pneumatic compression (IPC) did not reduce fluid in the legs of primary lymphedema (PLE) patients as expected. Instead, fluid increased in their untreated limbs, suggesting complex fluid shifts in PLE.

Area of Science:

  • Biomedical Engineering
  • Physiology
  • Medical Imaging

Background:

  • Fluid distribution changes in primary lymphedema (PLE) after compression are not well understood.
  • Standardized intermittent pneumatic compression (IPC) is a common treatment for lymphedema.

Purpose of the Study:

  • To measure fluid distribution changes in the lower limbs of individuals with PLE before and after IPC.
  • To compare the effects of IPC on fluid distribution in PLE patients versus those without lymphedema (NLE).

Main Methods:

  • High-frequency ultrasound (HFU) measured dermal fluid.
  • Bioimpedance assessed segmental fluid (Extracellular Fluid/Intracellular Fluid ratio - ECF/ICF).
  • Percent water content (PWC) measured fluid at specific anatomical points.

Main Results:

  • IPC significantly reduced ECF/ICF in the leg for both NLE and PLE groups, and in the treated lower limb for NLE.
  • No significant fluid reduction was observed in the treated limb of PLE patients.
  • The untreated limb of PLE patients showed a significant increase in ECF/ICF, unlike NLE.

Conclusions:

  • The foot, commonly affected in PLE, showed no fluid response to compression.
  • Increased fluid in the untreated limb of PLE patients highlights the need for further research into compression's effects on fluid distribution in PLE.
