Signs of Bad Circulation
Decreased Blood Pressure and Cardiac Output
One of the primary indicators of poor circulation is a significant drop in blood pressure and cardiac output. This is often observed in conditions such as infantile malnutrition, where the hemodynamics are on the verge of circulatory failure. In such cases, there is a marked decrease in blood pressure, cardiac output, and stroke volume, along with a longer circulation time and increased capillary permeability for fluids and proteins.
Cold and Discolored Extremities
Patients with poor circulation frequently report cold and discolored extremities. This symptom is often seen in milder forms of angio-spastic and angio-paralytic diseases, where extremities may appear habitually blue and cold without other significant symptoms of ill-health. This condition is sometimes mistaken for a weak heart, although there is usually no indication of cardiac weakness.
Impaired Circulation in Severe Febrile Illness
In children with severe febrile illnesses, signs of impaired circulation can be critical. These signs include severely impaired circulation, which can lead to increased mortality if not managed properly. Studies have shown that fluid boluses, compared to maintenance fluids, can increase the risk of mortality in children with signs of impaired circulation.
Increased Systemic Immune Inflammation Index (SII)
A novel predictor of poor circulation, particularly in coronary artery disease, is the Systemic Immune Inflammation Index (SII). High levels of SII, along with elevated C-reactive protein (CRP) and neutrophil/lymphocyte ratio (NLR), are associated with poor coronary collateral circulation. This suggests that inflammation plays a significant role in circulatory health.
Oxygen Debt and Lactic Acid Accumulation
Circulatory failure can lead to significant metabolic disturbances, including oxygen debt and lactic acid accumulation. These chemical changes in the functioning tissues are indicative of poor circulation and are often associated with muscular effort. The inability to meet the physical needs of the body due to inadequate blood circulation per unit of time is a clear sign of circulatory failure.
Reduced Cardiac Output in Chronic Fatigue Syndrome
Patients with chronic fatigue syndrome (CFS) often exhibit signs of poor circulation, such as reduced cardiac output and stroke volume. These patients, especially those with severe CFS, show significantly lower cardiac output compared to less ill patients and healthy controls. Symptoms like post-exertional fatigue and flu-like symptoms are predictive of lower cardiac output in these patients.
Symptoms of Posterior Circulation Ischemia
In cases of posterior circulation ischemia, common symptoms include dizziness, unilateral limb weakness, dysarthria, headache, and nausea or vomiting. These symptoms are often accompanied by signs such as gait ataxia, unilateral limb ataxia, and nystagmus. The presence of these symptoms and signs can help in diagnosing the specific vascular territory involved in the circulatory disturbance.
Conclusion
Recognizing the signs of poor circulation is crucial for timely diagnosis and management. Key indicators include decreased blood pressure and cardiac output, cold and discolored extremities, impaired circulation in febrile illnesses, high SII levels, oxygen debt, reduced cardiac output in CFS, and symptoms of posterior circulation ischemia. Understanding these signs can aid in identifying underlying circulatory issues and implementing appropriate interventions.
