What causes decreased peripheral perfusion?
In this regard, what causes decreased tissue perfusion?
Ineffective Tissue Perfusion. Many conditions can disrupt the exchange of oxygen and carbon dioxide, but diabetes, obesity, anemia, high blood pressure, and coronary artery disease are some of the more common risk factors that can cause ineffective tissue perfusion.
One may also ask, what are signs of poor perfusion? Symptoms of poor circulation
- Numbness and tingling in extremities. One of the most common symptoms of poor circulation is numbness and tingling in the hands and feet.
- Cold hands and feet.
- Swelling in the lower extremities.
- Cognitive dysfunction.
- Digestive problems.
- Joint pain and muscle cramping.
- Skin color changes.
Keeping this in consideration, what factors affect perfusion?
Tissue Perfusion: Cardiac
- Cardiac output is dependent upon heart rate and stroke volume.
- Stroke volume will be influenced by preload (filling pressure), afterload (systolic resistance), and contractility (force of contraction).
- Heart rate is dependent on sympathetic and parasympathetic balance.
How does hypertension cause decreased tissue perfusion?
The primary function of the microcirculation is to supply oxygen and nutrients to tissues. In hypertension, capillary rarefaction induces an increase in blood pressure, a relative decrease in tissue perfusion and an increased cardiovascular risk.
