Assessment of the Cardiovascular System III: Palpation01:27

Assessment of the Cardiovascular System III: Palpation

159
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...

Venous Return01:04

Venous Return

2.4K
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...

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

2.9K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Cardiac Output II: Effect of Stroke Volume on Cardiac Output01:22

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

537
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Veins of Lower Limbs01:15

Veins of Lower Limbs

407
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

Veins of Upper Limbs01:17

Veins of Upper Limbs

363
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

Summary
This summary is machine-generated.

Reduced venous return in the paretic hand may contribute to hand edema after stroke. This study measured hand edema and venous flow, finding significantly lower flow on the paretic side in stroke survivors.

Area of Science:

  • Neurology
  • Vascular Medicine
  • Rehabilitation

Background:

  • Venous congestion is a suspected cause of hand edema in stroke patients.
  • Previous research has not specifically examined reduced venous return in the paretic hand.

Purpose of the Study:

  • To investigate the relationship between venous congestion and hand edema in stroke patients.
  • To objectively measure hand edema and venous return in the paretic and non-paretic limbs.

Main Methods:

  • A cross-sectional study involving first-ever stroke patients with hand edema.
  • Hand edema measured using a volumeter; venous flow in the axillary vein assessed via ultrasound.
  • Paired t-test used to compare measurements between paretic and non-paretic limbs.

Main Results:

  • The study included 13 male stroke patients with a median age of 69.3 years.
  • Significantly lower axillary vein flow volume was observed on the paretic side (64.7 mL/min) compared to the non-paretic side (115.9 mL/min).

Conclusions:

  • Findings suggest reduced venous return may be associated with hand edema in stroke survivors.
  • Further research is needed to explore the mechanisms of impaired venous return and other causes of hand edema.
