Ultrasonography01:17

Ultrasonography

4.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Assessing Blood pressure using a doppler ultrasound

1.2K
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.

Ultrasound I: Abdominal Ultrasonography01:20

Ultrasound I: Abdominal Ultrasonography

180
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Assessment of the Cardiovascular System III: Palpation

198
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...

Area of Science:

  • Vascular Ultrasound
  • Point-of-Care Diagnostics
  • Medical Imaging

Background:

  • Point-of-care ultrasound (POCUS) applications in vascular imaging have broadened significantly.
  • Its use extends beyond procedural guidance across various medical specialties and clinical environments.

Purpose of the Study:

  • To review the current literature and applications of POCUS for extremity veins and the abdominal aorta.
  • To provide guidance on relevant anatomy, acquisition techniques, associated pathologies, and potential pitfalls.

Main Methods:

  • Literature review of pertinent studies on POCUS for vascular applications.
  • Description of anatomical structures and ultrasound acquisition protocols.
  • Discussion of common pathologies and diagnostic challenges.

Main Results:

  • POCUS is well-supported for diagnosing lower extremity deep venous thrombosis.
  • Evidence for upper extremity thrombosis and abdominal aortic aneurysm screening using POCUS is still developing.
  • The review synthesizes current knowledge on POCUS for these vascular applications.

Conclusions:

  • POCUS is a valuable tool for vascular assessment, with established utility in some areas and emerging potential in others.
  • Further research is needed to solidify the role of POCUS in diagnosing upper extremity thrombosis and screening for abdominal aortic aneurysms.
