What are Physiological Measurements?

Physiological measurements are objective data collected to evaluate the function and activity of the human body. These measurements provide insight into various aspects of physiology, such as the functioning of organs, blood circulation, respiration, metabolism and neurological activity. They are commonly used in the medical field, both for diagnostic purposes and for monitoring a person's health status.

Here are some common physiological measurements:

  1. Blood Pressure: The measurement of the pressure exerted on the blood vessels during the cardiac cycle. It consists of two values, the systolic (upper) and diastolic (lower) pressure, expressed in millimeters of mercury (mmHg).

  2. Heart Rate: The number of times the heart contracts and relaxes per minute. It is measured with a wrist or heart rate monitor.

  3. Respiratory Rate: The number of breaths per minute. This can be measured by chest movement or by using a spirometer.

  4. Body temperature: The average internal temperature of the body. It can be measured using a thermometer, usually oral, rectal, axillary or through the ear.

  5. Blood oxygen saturation (SpO2): The percentage of oxygen bound to hemoglobin in the blood. It is often measured using an oximeter placed on the fingertip.

  6. Electrocardiogram (ECG): A measurement of the electrical activity of the heart, where electrodes are placed on the skin to record heart rate, arrhythmias, and other abnormalities.

  7. Blood Test: Analysis of various blood parameters, such as cholesterol levels, blood sugar, kidney function, liver function, blood cells, and electrolytes. This can provide information about overall health and organ functioning.

  8. EEG (electroencephalogram): A measurement of the brain's electrical activity. It is often used to diagnose epilepsy, sleep disorders, and other neurological conditions.

  9. Spirometry: A measurement of lung function, including vital capacity, airflow, and lung volume. It is commonly used in the diagnosis and monitoring of lung diseases such as asthma and chronic obstructive pulmonary disease (COPD).

These measurements help doctors and health professionals obtain objective information about a person's physiological state. They are invaluable in making diagnoses, assessing health status, monitoring treatment progress and identifying potential health problems.
