Vital signs are key indicators that depict the basic functions of the human body. Vital signs are measured in medicine during the physical examination to check vital functions.
Vital signs are recorded using either single (discrete) or permanent (continuous) measurement. The discrete measurement reflects the values at a specific point in time X. A single vital sign measurement includes, for example, heart rate, body temperature, blood pressure and respiratory rate. The electrocardiogram (ECG), pulse oximetry (oxygen saturation of the blood) and electroencephalography (EEG) again fall under the continuous measurement of vital parameters.
