Blood flow measurement is a technique used to assess the circulation of blood within the body. It helps in understanding how well blood is delivered to various organs and tissues, which is crucial for diagnosing medical conditions. Various methods, such as Doppler ultrasound and thermodilution, are employed to measure blood flow accurately. These measurements can provide valuable insights into cardiovascular health and can help detect issues like arterial blockages or heart disease. By monitoring blood flow, healthcare professionals can make informed decisions about treatment and interventions to improve patient outcomes.
