Abstract

Introduction:

Quantification of blood flow to muscle using ultrasound is limited to large vessels. Small vessel intramuscular blood flow cannot be quantified using ultrasound without specialized methods or intravenous contrast.

Methods:

We describe a technique using power Doppler to quantify postcontraction hyperemia in intramuscular vessels that can be used at the bedside.

Results:

In 11 healthy subjects, postcontraction intramuscular blood flow in the forearm flexors and tibialis anterior muscles increased with stronger and repeated contractions. Intravascular blood flow measured by pulsed Doppler in the brachial artery similarly increased. Three patients with muscular dystrophies showed a negligible increase of postcontraction intramuscular blood flow.

Conclusions:

Intramuscular blood flow can be quantified using power Doppler ultrasonography; it increases following contraction and may be reduced in patients with muscular dystrophies. This quantitative, noninvasive technique can be applied at the bedside and may facilitate studies of disease impact on intramuscular blood flow. Muscle Nerve 54: 872-878, 2016.

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.

Blood Flow

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.
