Physiological measurement refers to the process of quantifying biological functions and processes in living organisms. This can include measuring parameters such as heart rate, blood pressure, body temperature, and respiratory rate. These measurements help in assessing the health and performance of individuals, often used in clinical settings or research. Various tools and techniques are employed for physiological measurement, including electrocardiograms (ECGs) for heart activity, spirometers for lung function, and thermometers for body temperature. Accurate physiological measurements are essential for diagnosing medical conditions, monitoring health status, and evaluating the effectiveness of treatments.
